Final Post – History & Memory

Another summer research trip come and gone. I’m flying back tomorrow and after a final day that will be spent organizing my belongings and finding room in my pack for the books, conference swag, (and yes, gifts) I’ll be back to Omaha. It’s helpful at this point to step back and take a look at what I’ve learned. Did I complete the goals that I laid out in my first post this summer?

First and foremost were my writing goals. I now have a revised first chapter of my manuscript and have A healthy start on the second. (goals 1 and 3). This was by far the most difficult goal to accomplish, however. Finding time to write on the road was much more difficult than in years past. In comparison, last year’s trip was relatively static. I spent weeks-on-end in one location, usually The Hague. This was ideal because the material I needed was always close at hand. Sadly, this was not the case this year. I spent equal time in The Hague and Amsterdam for research, but also planned work trips abroad. My biggest regret about my planning for this summer was trying to do too much in too many places. I had an inkling this would be the case already in my first few days abroad. I tried to combine my trip to Croatia for ESEH with a good amount of writing. To my surprise and (later) dismay, this would be the most productive writing phase of the trip. Later brief visits to Antwerp and London, while useful in terms of meeting colleagues and visiting archives, were far shorter and not conducive to producing written work. Had I the chance to rework my schedule, I would have clustered all of these trips near the beginning or end of my summer travels, leaving larger chunks of time in the middle.

Completing the first chapter required careful thought and significant reading of new material related to the subject of Dutch decline. I’m consistently surprised how little is written about the subject, especially outside the realm of economic history. An exception, however, is the work of cultural historian Wijnand Mijnhardt. Mijnhardt is one of the few working cultural historians that has focused on the subject of decline, particularly in how it relates to the Dutch Enlightenment. The Enlightenment will not be a primary focus of my book project, but the attention I pay to technological and medical change necessitates greater attention than I paid in the dissertation. Peter Gay’s assertion that the Enlightenment can be characterized as a

recovery of nerve,” I think, works in the Dutch context, especially in the early eighteenth century. During the Enlightenment, Gay asserts, fear of change gave way to “fear of stagnation” and that “the word innovation…became a word of praise”. This fits the Dutch experience of decline quite neatly. “Recovery,” however, may not be the most apt choice of terms in the Dutch context. The Dutch seventeenth century, as has often been demonstrated, was relatively anomalous compared to its European neighbors. While much of Europe struggled to weather the tribulations that took place during the “crisis of the seventeenth century,” Dutch culture and power flourished. Part of this success must be laid at the feet of Dutch innovation in shipping, maritime technology, hydro-technology, and economic organization. “Tradition,” however, was also respected and we see even in the early eighteenth century a balance being sought between the power of innovation as rhetoric justifying change and the power of custom and tradition when seeking to maintain those gains. I have already expanded on this subject in a 2015 article on the Christmas Flood of 1717, but intend to elaborate on this much more in later chapters as well. Is it accurate to call this balance-seeking a “recovery” of nerve, or was it a “negotiation”? I’m inclined to promote the latter interpretation.


Not all of my time was spent writing, however. I visited archives in London (related to a completely separate project), The Hague, and Groningen. In the process, I found the documents needed to plug a few of the more glaring holes in my documentation. I met with colleagues in academic and social contexts, whether at their weddings, at ESEH in Zagreb, or canoeing through the web of canals and lakes extending northeast of Leiden. Each experience deepened the relationships and friendships I’ve developed with these scholars. Every year, it seems, brings new opportunities to discover new parts of the Low Countries and it’s a joy to share those experiences with friends.

2017 was also the 300 year anniversary of the Christmas Flood. To commemorate the event, the province of Groningen, the Groninger Archieven, and several local and regional associations put together a series of events about the flood. The most prominent (and longest in duration) was a collaborative art project that featured Dutch and foreign artists developing and installing public art along roadsides and bike paths in the affected rural landscapes of Groninge

n. I took one of my final days to travel up to Groningen to see this installation. This was my first visit to this part of Groningen. I biked through towns and villages I’d only heard of from 18th century documents, and only in the context of disaster. This was a living landscape landscape, however, dotted with church steeples and omnipresent farms, far from the desolate disaster-scape I often depict in my work. My immediate reaction was confusion. Almost immediately after I stepped off the train in Winsum to rent my bike, I found it difficult to envision this region as a site of catastrophe. Biking toward the coast, however, my impression changed. North of the town of Pieterburen (now a tourist attraction because of its seal rehabilitation center), the landscape empties. The open fields filled with crops and flowers were both beautiful as well as a potent reminder of how flat and vulnerable this region was (and potentially still is) to flooding. The village of Pieterburen was heavily impacted by flood of 1717. They lost 172 people, dozens of houses, and hundreds of livestock. Little evidence of this vulnerability remains. There are no permanent markers to the flood and even the old sea dike (oude zeedijk), though still relatively large and solid, shrinks to insignificance when compared to the new, massive sea wall protecting the coast. Looking out beyond this permanent barrier, meadows scattered with cattle and sheep extend to the distance. The impression of this landscape is one of near total control. This landscape of recreation and Arcadian productivity is a monument, not to disaster and vulnerability, but the mastery of nature.

The landscape between Pieterburen and the old sea dike. The trees in a row in the distance are the old sea dike. Beyond that is a polder constructed in 1718 after the flood. Beyond that, the Wadden Sea tidal flats. The landscape is nearly completely flat with the exception of the new and remnant sea dikes and scattered housing mounds.


Roger Rigorth’s “Water Horizont” recalls the working history of the Wadden Sea as well as disaster. The nesting structures are made in a traditional weaving technique using the 17th century. Their height represents the highest level of water in 1717. For a description of the production of this work (and others along the Groninger coastline) see the Verhalen van Groningen. Video embedded below.

Of course, this is a dangerous interpretation and one which the many organizations that build and maintain these landscapes both foster and fight against. The memorialization of the Christmas Flood is an effort to temper this feeling of triumphal security. The art installations along the coast recall the Christmas Flood, but they also connect it to present-day insecurities. Some explicitly connected this historic landscape of disaster to modern climate change or instances of disasters like Katrina or Southeast Asia tsunamis. The message was clear. The most vulnerable populations are those without memory or history. Biking along the coast and back toward Groningen, it occurred to me that this is not a new challenge. In 1719, an anonymous pamphleteer described the flood and its consequences for his readers. His story was necessary, he argued, so that “eternal memory [of the flood] may be preserved.” Public art may be a novel approach, but in spirit, it captures the same mentality in evidence for centuries. Mind the next flood.

Tot volgende keer Nederland.

Exploring Colonial Records at Kew

The area currently called West Feliciana Parish, Louisiana is a relatively recent entity, but one with a long history of Euro-American settlement. Prior to 1824, when it was under American administration, the area had been one half of a larger territory simply referred to as Feliciana Parish, with the remainder of the parish extending eastward to the Amite River. Prior to American period, which began in 1810 (it was not included in the Louisiana Purchase), West Feliciana Parish had also been part of several colonial Empires. Between 1784-1810, it had been part of the Spanish Empire. Prior to that, it had been controlled by the British, who obtained it from the French at the conclusion of the French and Indian War. Although the imprint of French settlement was faint in the parish, one still sees the French colonial influence in place names and surnames of inhabitants. Each successive colonial administration governed the organization and sale of territory to settlers. As a result, land claim and land tenancy records of these early settlements exist in a number of locations, both in Louisiana and in Europe.

West Feliciana Parish is flanked by the southern edge of Mississippi, the Mississippi River to its west and East Feliciana Parish to its east. Image:

The National Archives at Kew in the UK house some of the earliest records of British tenancy in the region. Under British colonial administration, West Feliciana Parish was part of a larger area known as the “Natchez District.” It was during the British period that West Feliciana Parish saw its earliest significant European settlement and the records for this movement of people now reside in Greater London. The National Archives contain a large collection of British land claims and exchanges. They also contain early surveys and other cartographic data related to the Natchez District. It was the chance to (digitally) obtain these maps that drew me to the UK this week. Ordinarily, this trip would be infeasible, especially for so short a visit. Since I was already in the Netherlands working on other research, however, the opportunity to visit the archives seemed too tempting to pass up. London is only a cheap and (relatively) quick train ride away from Amsterdam.

My interest in the property and cartographic history of West Feliciana Parish relates to a larger project I have been conducting with Dr. Sara Sundberg at the University of Central Missouri, which explores the social, gender, and environmental history of the region. West Feliciana was a borderland region during the Early Republic, recognized by settlers to be a location of significant economic potential due to its proximity to major trade routes along the Mississippi River and its fertile agricultural soils. Women and men settled the area in the 1780s under British rule and continued to expand their families and fortunes into the American period. The initial stage of this project was to map out the economic role of women during the transition from Spanish to American rule. We discovered that women played a disproportionately large role in the buying and building of family estates in the early 19th century, a fact made possible by legal and social rules facilitating this process. This part of Louisiana history has been explored by Dr. Sara Sundberg in her article “Women and Property in Early Louisiana: Legal Systems at Odds,” Journal of the Early Republic 32 (Winter 2012), 633-665 . Both Dr. Sundberg and myself expanded on this subject in a recent article in the journal Agricultural History that investigated the environmental and agricultural context of women’s land use decisions, entitled “Happy Land: Women Landowners in West Feliciana Parish Louisiana, 1813-1845” (2016). We have since expanded our scope to include the earliest settlement in the region. Who were the earliest settlers in the region and where did they site their plantations? What role did women play in the earliest settlement? Did people prioritize specific parts of the parish and why?

The first steps in resolving these questions were taken last summer with the help of my research assistant Miranda Lonsdale. Miranda, a graduating senior at Creighton University, cross referenced land title information she obtained from the American State Papers and with digitized documents available through the Louisiana Office of State Lands A summary of that early work can be found in an earlier blog post. As interesting as this information was in revealing the condition of settlement after 1819 when the Felicianas were officially incorporated into the Union, they gave only faint clues about early settlement. For this information, we are now turning to colonial records, in particular early maps.

Prior to the American period, the most thorough surveys of the Felicianas had been conducted by Vicente Sebastián Pintado, the Spanish Surveyor General of Spanish West Florida. His work included both cadastral and topographic detail and his papers can be found in the library at LSU and at the Library of Congress. Several dozen of his surveys can be found online in publicly available, digitized form through the Library of Congress website. An undergraduate researcher at Creighton, Cole Fournier, is currently georeferencing several of his maps that cover our study area. His work will help extend our scope back to the Spanish era. Although the Spanish had officially claimed the region since the 16th century, true settlement only began under the French in the 18th century and the British were the first to actively settle the Felicianas. One of the most significant early British maps of the Felicianas (indeed, the entire Natchez district) can also be found online courtesy of the US Army Corps of Engineers. This “William Wilton map” (1774) is a large, beautiful cadastral survey of this entire region. It gives a clear, though by no means comprehensive, overview of early British settlement, including the area of West Feliciana Parish. This was not the official map produced for the British government, however. Those maps were produced by surveyor Elias Durnbar and are available at Kew. They lack the topographic detail of Pintado’s later production and the scope of the Wilton maps, but provide additional information about the location and names of early settlers. Light Townsend Cummins has already traced the lineage of early British settlers using primary Spanish and American archives to established the enduring presence of about 30% of these settlers in the Parish. His work did not explore the geographic or demographic character of this settlement, however. These maps give us the first clue about the important connections between geography, gender and the environment in Colonial Louisiana.

The facade of the National Archives at Kew and the retaining ponds in the front of the building

The National Archives at Kew are not picturesque, not particularly accessible, nor are they the tourist draw that you see in the US or in other European countries. That said, they are incredibly well-used and thoughtfully organized. Constructed in the early twentieth century in an area that has witnessed numerous floods preceding and following their construction, the sole visually impressive feature of its exterior are a series of ponds. They are home to a family of swans and other waterfowl, but they double as a reservoir. Inside the building, the archive runs like a well-oiled machine. The combination of an online “discovery” portal and self-service monitors that allow you to request material and check on the status of your orders meant that much of the work of “getting to know” the archive was streamlined and I was easily able to explore the collections with little assistance. To make my work easier still, all of the material I was interested in were housed in two related repositories, both within the Records of the Colonial Office, Commonwealth and Foreign and Commonwealth Offices, Empire Marketing Board, and related bodies.

This example of a Durnbar survey required an entire oversized table to read. It listed the names of each grantee and depicted their location along the Mississippi (or near it)

All of the maps arrived in rolls and because of the nature of settlement (“vertically” up the Mississippi), they were typically several feet in height. Four of the five maps I requested yielded useful information about the original British land grants. Receiving “grants” from the British government did not mean that claimants actually resided in these areas. Indeed a number received grants in locations as far away as Pensacola Florida. Others received multiple grants in the same general area. An example of this latter category was Frederick Haldimand who was granted two, non-adjoining sections. The grants themselves listed a number of requirements of grantees that needed to be fulfilled within three years (including bringing land into cultivation and building a house). Even so, land grants were subject to land speculation. Grantees could lease their lands. Looking over the grantee rolls, one sees a number of familiar names, not the least of which were Elias Dunbar (the surveyor), William Wilton (mapper), and Peter Chester (Governor of West Florida). Government service apparently paid. It certainly did for veterans for the recent French and Indian War who were also allotted land in West Florida as payment for services rendered during the war.

All of the grantees with an “R.O” beside their name were officers who fought in the Seven Years War.

The map notes the presence of Tunica Indians in the bend of the Mississippi in the southwest corner of the Parish.

The relationship between land grants and later residence is a subject that warrants further investigation, as is the spatial organization of early settlement. Even a cursory analysis of the maps reveals some clear patterns. Early arpents were granted along major watercourses. Naturally, the Mississippi River was prime real estate, although the swamp on the east bank of river in the southwest of the Parish appears to have been reserved for the Tunica tribe. Settlement even extends to the bluffs of what are now the Tunica Hills. “Clark Creek,” or what is called Bayou Sara today is another nexus of settlement, as is Thompson’s Creek. This creek would eventually divide East from West Feliciana, and already in the 1770s, it saw numerous grants on both sides of the river. The triangular area between the Mississippi and Thompson Creek appears to have the greatest density of early grants. It is somewhat surprising how widespread the grants are across the parish at this early date. Long lots appear in a number of physical regions, from the alluvial swamps in the southwest, to the oak, pine, beech uplands and lowlands that clustered around Thompson Creek. The single unifying factor was access to water-based transportation. This may be an indication of the limited familiarity grantees had with the area.

These and other conclusions remain, however, tentative. I still need to georeference the surveys and add this British grant data to the master map. This data did not provide complete answers to my initial set of questions either. Much of the Parish remained unclaimed (and certainly unsettled) by the time the British administration ended. Large expanses of the interior of the parish would later by granted and settled under the Spanish, a problem and project for another day. Now, however, its time to hop the train for the Low Countries, on my way to The Hague and a return to Dutch disasters.

Disparity and Solidarity: Reflections on the Christmas Flood of 1717 – Part II

The following is the second part in a series exploring themes related to the Christmas Flood of 1717. These maps and reflections are works in progress and reflect the status of the project at the time of the European Society for Environmental History’s Biennial conference in Zagreb, Croatia, 2017.

In the limited time available during conference presentations, it is often difficult to explore the full scope of the subjects discussed in accompanying papers. This was the case with the presentation I briefly outlined in my previous post about the Christmas Flood of 1717. The paper introduced a side-project I have been working on related to a chapter from my manuscript on eighteenth-century Dutch disasters. My motivation to explore this flood in comparative perspective grew from my desire to understand how the Dutch (specifically the Groninger) experience of disaster compared with that of its neighbors. As bad as natural disasters in the early part of the 18th century were for the Dutch Republic, they were far worse in East Frisia. But how to explore and visualize this difference? The experience of the Christmas Flood in East Frisia was a far more devastating, long-lasting affair than in Groningen. Did the divergence begin with the onset of the flood? One of the early strategies I used to explore these questions was to map the flood losses by municipality in Groningen and East Frisia. To my knowledge, this hasn’t been attempted and it revealed some striking geographic differences (and similarities).

Chief among these were the ways that flood victimhood had been distributed across the province and the principality respectively. Much of this information (and the maps) had to be left on the chopping block for the conference, so I will add a few final images for reflection.

Christmas Flood fatalities by municipality. Sources: Register, Van Geleden Verlies in de Provincie van Stadt En Lande – 1718 ; – Mortality information obtained from Jakubowski-Tiessen, Manfred. Sturmflut 1717: Die Bewältigung Einer Naturkatastrophe in Der Frühen Neuzeit. Oldenbourg: Oldenbourg Wissenschaftsverlag, 1992; Meyer, T.

Hubatsch, W. and T. Klein (eds.) 1975 ff.: Grundriß der deutschen Verwaltungsgeschichte – Marburg.

The first set of maps compare human fatalities. The underlying boundary shapefiles are loose approximations of actual administrative boundaries (less loose in the case of Groningen), but they give a general sense of the geographic distribution of victims. Most are concentrated along the Wadden Sea coast, less along the Dollard. This data is taken from a variety of secondary and primary sources. Areas near dike breaches naturally experienced the greatest fatalities. There is little surprising about this map, although they might be improved with accurate municipal population figures to give a clearer sense of the relative severity of the flood (something I haven’t been able to find so I’m relying on raw data). The takeaway from this map is that the experience of disaster on a provincial level is surprisingly similar between East Frisia and Groningen. In both areas, we see highly variable impacts, though in both cases, they are concentrated along the Wadden Sea coastline, largely centered on sea clay landscapes, populated by (relatively) well-off farmers.

Livestock losses during the Christmas Flood. Size of dots are proportional to the total number of livestock lost per municipality. Pie charts depict the percentage of livestock type lost by municipality. The key visual difference between Groningen and East Frisia is the losses of sheep (in Groningen) vs that of East Frisia, where the losses of cattle were heaviest. Sources: see figure I

Property loses show a subtly different spatial pattern to that of human fatalities. In Groningen, losses were heavier for property in the low lying reclaimed areas to the north and east of the city of Groningen, in the center of the province. Sources: see Figure

Compare this map to a similar series showing loss of housing and livestock. Subtle differences appear between human fatalities and property loss maps. Although the coasts remain hardest hit, the flood washed away a significant amount of property in the interior of the province as well. In Groningen in particular you see this trend develop. Why the difference? The areas to the north and east of the city of Groningen had been drained and were slowly subsiding, leaving the interior of Groningen bowl-shaped. In addition to the “young” and “old” sea clay polders (blue and green respectively), we see heavy losses in the reclaimed peat bog areas to the north and east of the city of Groningen (burnt orange). A notable exception is in the Western Quarter of the province which experience minimal losses (a subject explored in the previous post and full conference presentation.

The difference between human and property losses was probably partly the result of their location and the nature of the storm surge on Christmas Eve 1717. Drained bog landscapes were slowly subsiding and were significantly lower in elevation than the coastlines. However, the initial impact of the flood along the coasts would have come without warning. Contemporary accounts are unanimous in their description of the early moments of the flood, coming late at night, catching people leaving near the dikes unaware. In contrast, people residing inland would have had more warning. This is described in numerous local sources. The church book from the Groninger town of Woltersum, for instance, describes the event.

“In the day and time of trouble, people saw a white cloth flying on some of the low-lying houses of our polder as a sign of the urgent emergency! The somber sound of the clocks was heard, as distressing as they were insistent!”

“In dien Dagh en tijd der benaeuwtheid sagh men op sommige der lage Huijsen van ons carspel een wit doek waeijen, tot een teeken der dringende nood! Het nare geluijd der aangeroerde klokken, ellende gelijk als uijtroepende, wierde gehoort!”

Source: Doop, Trouw en Begraaf (DTB), Kerkelijke Gemeente Woltersum Kerkeboek 1638-1764 [online] fol. 178, 1717.

Presumably, there would have been less time to protect houses and livestock than human lives. At the same time, the bowl shaped interior would have held water in, preventing easy drainage.

With limited cultural landscape source material for this part of Germany, it is difficult to make an adequate comparison. It would interesting to see if this dynamic played out in both areas. Property damage seems to be more broadly distributed, indicating that other processes were at work. What they are, and how they related (if at all) to land use, is one area of the development this project could take.

One key difference, immediately apparent when we look to livestock losses, however, is their divergent specialization. Both regions had had a long history of intensive cattle production. By the early eighteenth century, cattle rearing and pasturing had become heavily commercialized and connected to the long-distance cattle trades stretching from Denmark to the markets in Amsterdam. Groningen and East Frisia were both centers of transshipment and cattle were raised and fattened on their fertile coastal meadows. The maps of flood losses, however, show a different picture of rural agriculture in 1717. East Frisia shows what one might expect. The majority of livestock lost are cattle, followed by sheep, goats, and horses. In contrast, Groningen appears to have been invaded by sheep! The livestock data reveals much heavier concentration of sheep losses than cattle. Without livestock censuses or other ways to measure this change (short of the tabulations of flood losses), it is difficult to tell when or why this transition occurred, but it cannot be coincidence that a massive cattle plague was ravaging herds between 1713-20 in the region. Is the predominance of sheep in Groningen indicative of an adaptation to rinderpest? In Holland, heavily capitalized farmers tended to restock herds, partly made possible by the increase in the price of beef and milk. Was this also possible in Groningen? If so, this would be particularly valuable evidence of an intersection between multiple disastrous events and confirmation of one of the key theses of my manuscript. It is also possible, however, that this is a dead end. Perhaps more sheep simply died in the flood, and the figures give a false sense of total livestock before the flood. Like the maps on property damage more broadly, these maps open up as many questions as they provide clues to the consequences of the Christmas Flood of 1717.

Disparity and Solidarity: Reflections on the Christmas Flood of 1717

The following are additional thoughts (and maps) that could not be included in my presentation during ESEH 2017. The paper as well as the powerpoint presentation, entitled “Boundless Water, Bordered Lands” can be found on my site for download.

Disasters are always disproportionate. They affect some people, some environments, and some social systems far more than others. Teasing out the reasons for these disparities and exploring their consequences and origins have been some of the more significant and consistent threads of natural disaster research over the past several decades. The social science of disaster often focuses on these questions and the way in which they challenge or reinforce existing social disparities. How do issues of gender, race, religion, or class affect the outcomes of disasters? Economically and socially disadvantaged groups, or groups without access to the political power necessary to mediate recovery, tend to lose most in the wake of disaster. These observations have taken on the importance of near-truisms, particularly in the realm of vulnerability studies. Historians of natural disaster have an important role to play in this dialogue. History provides a wealth of additional examples to test assumptions about the interplay between social and natural systems that create vulnerabilities and moderate social resilience (Van Bavel & Curtis) Just as importantly, as Greg Bankoff has previously asserted, vulnerability itself is an historical construct. (Bankoff, Time is of the Essence) The social hazards of living in low-lying areas, building wooden houses unable to withstand earthquakes or fires, or organizing communities without access to centralized disaster relief are products of far deeper histories of disenfranchisement and vulnerability.

In the context of the Christmas Flood of 1717, we see the truism of disaster disparity starkly reified. Although the flood is often considered a true “North Sea Flood,” affecting a huge area of its southern coastline, in reality, its impact was far from homogeneous.

Figure 3- The size of red circles represents the proportion of total losses during the Christmas Flood as reported in Jan Buisman, Duizend Jaar Weer, Wind En Water in de Lage Landen. Deel 5: 1675-1750. Franeker: Van Wijnen, 2006. It should be noted that the spatial extent of the Christmas Flood has been a source of consistent debate and extensive analysis. Already in 1720, G. Outhof criticized the accuracy of Homann’s map, from which this layer is derived. The most extensive critical analysis of this map can be found in D. Hagen Die jämmerliche Flut von 1717; Untersuchungen zu einer Karte des frühen 18. Jahrhunderts, Oldenburg 2005.

The degree to which this was the case is rarely the subject of research. In his book Sturmflut 1717, now a classic of the new disaster history, Manfred Jakubowski-Tiessen examines the flood and its impacts with a broad comparative lens. Although he wrote the book before the recent upswing in vulnerability studies, one could make the argument that the concept was central to his interests. The flood, as he describes it, catalyzed a strong and protracted economic and demographic decline in key areas, particularly the Butjadiger coast of Oldenburg, the Dithmarschen and East Frisia. He explores each as part of a larger flood disaster narrative that focuses on themes of cultural, social, and economic significance. Jakubowski-Tiessen limits himself, however, to German-speaking lands and as a result, the full power of his argument is difficult to conceptualize. How did the impact of the flood in East Frisia, for instance, compare with non-German-speaking areas affected by the flood?

Jakubowski-Tiessen’s book remains the seminal work on the Christmas Flood, though it does not cover the consequences in the Dutch Republic.

I explored this question in my conference paper, called “Boundless Water, Bordered Lands,” for the European Society of Environmental History Biennial Conference in Zagreb, Croatia in July 2017. I choose for my comparison the Dutch Province of Groningen and the “German” province of East Frisia. On paper, they appear complementary. They experienced roughly equivalent losses in human lives and property in the immediate aftermath of the flood. Almost immediately, however, their experiences diverged. Groningen quickly rebounded, whereas East Frisia proved far less resilient. Why was this the case?

Explanations might be sought in the type of dikes or their management. Both regions, however, constructed roughly similar coastal defenses maintained and financed by similar dike institutions (dijkrechten in Groningen, deichachten in East Frisia). Less proximate similarities run deeper still. Groningen and East Frisia were (and are) part of the Frisian cultural zone bordering the Wadden Sea, a thin intertidal space sandwiched between the mainland and an archipelago of barrier islands. For centuries, people living along the coast exploited the rich sea clay and interior peat soils and developed communities that shared numerous cultural, linguistic, and economic conditions. The similarities between dikes and dike institutions in East Frisia and Groningen were partly derivative of this deeper history and more recently, historians have explored their underlying unity in the context of shared vulnerabilities, adaptation, and resilience to coastal flooding. Variously termed a “coastal culture of disaster,” “hydrographic society,” or “amphibious society,” these concepts have been applied to communities along the entire North Sea coast, but tend to highlight particular relationships in coastal Germany and Holland.

East Frisia and Groningen are an ideal region for comparative analysis because of these and other connections. East Frisia, for instance, can be thought of as a near satellite of the Dutch Republic during the seventeenth and early eighteenth century. The largest city in the state, Emden, was arguably politically (and certainly culturally) closer to the neighboring Netherlands than the court of Aurich in the interior of the region. These East Frisians spoke Dutch, practiced Calvisinism, and were united in their antipathy for the Lutheran Princes of the Cirksena family that claimed sovereignty over the principality. The surface similarities between the two regions, however, were also the sources of subsequent tensions that would push Groningen and East Frisia onto diverging paths of recovery.

In the conference paper, I argued that the conflict between Prince Georg Albrecht and his Calvinist subjects along the sea clay coasts was a significant contributor to the divergent path East Frisia would take from Groningen in the aftermath of the Christmas Flood. The flood created severe financial difficulties and sparked social unrest in both regions (the Aduard uprising in 1718 in Groningen, and the Appelle Krieg of 1726 in East Frisia). In contrast to the Aduard uprising, which was highly localized to the lightly affected Western Quarter of Groningen, the East Frisian resistance exhibited far greater solidarity and power in the face of their Lutheran Prince. The indirect (and unintended) consequence of this solidarity was inaction in rebuilding their own dikes. Financial troubles were compounded by regional resistance to state-directed rebuilding efforts, which inhabitants viewed as a breach of their traditional rights. Subsequent floods in 1718 and 1720 destroyed what little repairs could be completed. Ultimately, it would take over 6 years to rebuild the dikes, during which time the landscape had remained susceptible to inundation, harvest failure, and continual out-migration. We should be very careful to contextualize historical interpretations of solidarity, particularly after floods. Communities could rely on multiple avenues to achieve solidarity, but they weren’t necessarily productive and didn’t always involve a recognition of shared risk to natural hazards (the presence of which disaster culture historiography depends on to a great extent).

During the question and answer period, Richard Unger asked what distinction should be made between “communities” and people with “shared interests” – an important distinction to be sure, but one that is often taken for granted in the historiography of “disaster cultures.” Most scholars who have weighed in on the subject, I think, would argue that shared interest in the face of natural hazard partly defined those communities’ cultures. These understandings were constantly contested and ever-changing, just as the broader cultures themselves evolved. Whether we can then transcend key differences and negotiate the shifting landscape of these relationships to find a “model” representative of all Wadden Sea cultures of coping with disaster remains an open question. The solidarity expressed by coastal communities in East Frisia in the aftermath of the Christmas Flood sharply contrasted with those in Groningen. This example demonstrates how issues of post-disaster solidarity, interest, and community were contingent on the underlying political and social issues at play in the wake of single disastrous events.

Next post: exploring the geography of vulnerability and the potential intersection of multiple disastrous events.

ESEH 2017 – Borders, Animals, and Nature

Conference themes don’t always (or even typically) define their content. Whereas keynotes and panels organized by program committees generally adhere to them, other sessions and events or just as likely to ignore the themes entirely. This is part of the reason that I rarely remember them. Conference “character” is more often defined by location, socializing, and/or interesting papers. In some exceptional circumstances, conferences can even be defined by their weather (such as the extreme heat of ESEH in Versailles). Effective themes, however, can provide a backbone of connectedness and dialogue between and amongst the disparate sessions, events, and meetings throughout the conference. ESEH 2017 in Zagreb adhered to this second model. Although not always fluidly executed, the conference as a whole nevertheless consistently explored its theme of “Natures in Between: Environments in areas of contacts among states, economic systems, and religions.”

The two most explicit connections to these themes were drawn from the opening address and plenary roundtable about migration. Andrew Baldwin’s opening lecture provided a provocative (or to use his own word: uncomfortable) introduction to the theme. Ostensibly about climate migration, Baldwin’s talk became more of an anthropology of whiteness and the hypocrisy of post-racial narratives of migration. Baldwin had the fortune (or perhaps misfortune) of speaking on the first, and hottest day of the conference, in the gorgeous Croatian State Archives. Baldwin’s talk received mixed reviews. On the one hand, environmental historians found little of “environmental” significance in his talk (which was possibly the real source of people discomfort, rather than its racial subject matter). On the other hand, I, and I imagine others, appreciated Baldwin’s sort of iconoclasm and rejection of what has come to define “European” environmental history. European environmental history is heavily invested in theory, but far less in discourse and narrative analysis, both of which Baldwin drew heavily upon. As his talk revolved around forced movement of peoples, it absolutely fit the theme of the conference.

The opening lecture took place in the stately central hall of the Croatian State Archives.

In retrospect, it shouldn’t have been surprising how migration and movement became the watchwords of the conference. Between refugee crises and their consequences in Europe and apprehensions about the devolving state of immigration in the US, historians already interested in borders and their transgression found plenty of material for contemporary comparison. In addition to Baldwin’s talk, the plenary roundtable on migrations was another case in point. Also like Baldwin’s talk, it received mixed reviews. Starting off the discussion, Marco Armeiro’s first pitch to the panelists was an (intentional?) softball, asking each to react to his provocation – that environmental historians have largely ignored migration as a subject. Naturally they disagreed, and all for valid reasons, though most also emphasized the need for greater emphasis in the future. Shen Hou’s comments were particularly well put, drawing primarily from the “classics” of EH literature (Dust Bowl, Changes in the Land), but leaving plenty of room for future contributions. The discussion only truly took off, however, when the mic was offered to the audience. Although the quality of answers were mixed, thoughtful, challenging questions redirected the discussion into new and arguably more productive and innovative directions. Thinking about migration across borders as a normative condition, for instance, and sedentism as the questions requiring an answer, or substituting corporations for nation states in our dialogue of migration pushed the audience and panelists to rethink their assuptions. Naturally, this discussion could have gone on far longer. Peter Coates, for example, was brought into the discussion largely based on his expertise on historic invasive species, and I would have loved to hear his take on the limits to the animal-human analogies he was encouraged to make. Likewise, the consequences of language and labeling of “refugees,” “migrants,” and “invasives.” Regardless of its shortcomings, the plenary was a useful thematic bookend that recalled topics and themes related to “contact” areas from the previous days’ sessions.

The most surprising development of the conference, however, was the “animistic turn” European environmental history seems to have taken over the last few years. Histories of animals (wolves, whales, cattle), animal movement (epizootics, bio-migrations) and non-human nature more broadly were conspicuous for the number of sessions devoted to them as well as their attendance. The experimental session on “more-than-human” storytelling had a packed house. It was an exercise in unstructured, team-brainstorming. Session leaders challenged groups of scholars to think through key methodological and epistemological questions about the nature of narrative storytelling, anthropomorphism/centrism, and agency. Although the intention was to de-center (at least temporarily) the human from historical thinking, it ultimately did the opposite. Thinking about “beyond-human” agency casts the significance of human action into even sharper relief. Its absence is clearly felt and significance expressed. This may be the single most useful contribution of this type of exercise.

In a certain sense, focusing on animals during the conference, in particular this exercise in non-human storytelling, were surprisingly appropriate subjects for this conference about borders and contact. Plenty of papers (my own included) dealt with historical subjects across state, economic, and religious borders. I found that the most interesting moments of the conference came when people crossed disciplinary borders (Baldwin), narrative borders (more-than-human panel) and made contact with the “Natures in Between” those spaces.

The plenary roundtable took place in the main university building adjacent the archives.

Travel & Familiarity – Research Blog Summer 2017

Displaying FullSizeRender.jpg

The Amsterdam Canals seen from the north. (this was actually the first time I’ve flown over the city on a clear enough day for this view).

Flying back to the Netherlands for another summer of research, conferences, and writing, I had expected the transition to occur awkwardly after about a year away. Eleven months is a long time to be gone. You’re in a different place with your work, friends and colleagues move their lives and interests, and the cities you’ve grown familiar with evolve. I find that I have to completely shift into a different head space come summer because so much of my time and energy during the year is spent teaching or working on other projects. The shift to research and writing full time is a welcome change, but one that has to take place quickly and deliberately. I have similar apprehensions every year, but I’m beginning to realize I shouldn’t. As much as people and places change and as much as I become engrossed in other projects after I leave, the underlying familiarity and warmth (well not literal warmth) of the Holland welcomes me back every year.

This was a nice realization and a starting point for my month-long stay in Europe this summer. It’s Tuesday June 27th and I’ve now been in Holland about a week. This is the first post of summer 2017 in a series detailing my research and time spent in Holland and abroad. It will be a busier than average summer, largely because I’m only here for 30 days (a short stay compared to last year), but also because so much of my time will be spent in transit. As in years past, I’m beginning the summer with a conference outside the Netherlands. The European Society for Environmental History (ESEH) is hosting their biennial conference in Zagreb, Croatia this year and I’ll be presenting on an old theme for the first time in years, coastal flooding! (More on this to come) I also have trips planned to Rome, Antwerp, and London. The latter will be short, a two-day stay near the National Archives at Kew. It will be my first time in British collections and a necessary next step in a slowly expanding project on West Feliciana, Louisiana. In later posts, I will detail my objectives and findings, but suffice to say, I will be doing a lot of writing on planes and trains.Logo_ESEH_2017

I also plan to take a weekend to visit Groningen. Groningen is a beautiful northern province, well worth a visit on any occasion. 2017 is perhaps the most ideal year to visit, however. This is the 300th anniversary of the Christmas Flood! In commemoration of this near-forgotten event, the province, the Groninger Archieven, and a number of cultural organizations have put together a summer-long program of lectures, excursions, and exhibits related to its history. They also have a fantastic website that links to primary and secondary sources (including one by yours truly) on the history and significance of the flood. Coincidentally, my conference paper for ESEH also explores the history of the Christmas Flood, so it was a completely natural decision to plan a visit. It also hasn’t escaped my attention that, with the exception of a couple Wadlopen excursions (and none since 2014), I’ve been a really poor visitor to the province (hardly ever leaving the center of Groningen). Time to remedy that.

Somewhere amidst this travel, I will also have to find time to research and write. In contrast to last year’s narrow set of research goals, this year will be spent largely writing and wrapping up loose ends for my book manuscript, Floods, Worms, and Cattle Plague: Natural Disaster at the Closing of the Dutch Golden Age. With the exception of a few books and archival documents I need to find in The Hague, Groningen, and Amsterdam, the research is largely complete (or at least as complete as it will be). My time will be largely spent writing and editing the manuscript and my goals for the summer are consequently related to that process.


  1. Complete a draft of chapter one. This chapter frames the core issues of the book. It explores the meaning of disaster in the early modern era and how it tied in to the eighteenth-century decline of the Dutch Republic. In contrast to later chapters that address individual disasters and more defined and limited themes and time periods, this chapter performs a balancing act between narrative explanation of themes and questions (often in the longue durée) and the narrative specificity of my hook, the famous disaster year (rampjaar) of 1672.
  2. Writing the first chapter requires dealing with a theme that has received far less scholarly attention than I would have expected– the decline of the Dutch Republic. Although decline has enjoyed substantial attention from economic historians since the publication of Joh. de Vries Economische achteruitgang der Republiek in de achittiende eeuw (1968), far fewer scholars investigate the subject from its cultural or social perspectives, much less environmental. This peculiar historiographic oversight will be a subject for a later post, but suffice to say for now that I will be able to investigate the topic more effectively in such close proximity to the archives and especially libraries of the Netherlands.
  3. Begin revision of Christmas Flood chapter. It is not the second chapter, but I may as well turn to it next since so much of this summer revolves around the disaster anyway. This is easily one of the more polished chapters already, but there are a few documents I need to find in the Groningen archive.

Next post, from Zagreb!

Final Post

This will be the final post of my research blog for this summer. I’ll be flying out of Holland tomorrow and I’m reminded how leaving is always bittersweet. From a personal perspective, a month and half is an awkward length of time to live abroad. Not long enough to really feel settled, but certainly long enough to feel a significant amount of distance develop between your everyday experiences and those happening back home. This summer in particular, I was very fortunate that my research trip coincided with moments of great transition in the lives of friends and colleagues in the Netherlands. I’ve seen them get engaged, start families, and start new jobs. I’m very grateful to have been able to share in those experiences. From a professional perspective, no place beats the Netherlands for my research and this has been one of the most productive periods of my (albeit very new) professional life. With the archives, libraries, colleagues, and landscape of the Netherlands a stone’s throw away, reading, writing, and thinking about Dutch environmental history seems a natural outgrowth of waking up every day. One day out from the journey home, therefore, it’s relatively easy to take stock of what has been achieved.

I laid out three broad research goals in the first installment of the 2016 research blog and I’m happy to report progress on each.

1. My first goal was to get to the bottom of some historiographical inconsistencies I discovered concerning the early years of the shipworm epidemic. I elaborated on these problems in some detail in my first blog on the “unusual connections” between disasters so I won’t rehash them here. In short, the beginning of the shipworm epidemic is often dated to November 1730. According to most accounts, this was the first verifiable, consistent, explosive outbreak of the species in Dutch waters (though there is some evidence of wood borers and perhaps even Teredo navalis earlier). Several historical accounts, however, report an earlier outbreak in 1728 on the island of Goeree.(1) In my earlier blog, I noted how difficult it had been finding evidence of this supposed outbreak. The notes from the “Statenvergadering” of the Estates of Holland on 19 Aug, 1728 certainly mentioned the island and its wooden piles, but there was no mention of shipworms. The notes of a subsequent report presented in the Spring of 1729 likewise turned up no evidence of shipworms. Even following a severe storm in December of 1729 when numerous piles had been broken (the exact situation that would prompt discovery of the shipworms in Zeeland and Holland in 1730/31 respectively), the notes make no mention of the mollusks.

An example of a “resolutiekaart” found the resolutions of the Estates of Holland. This hand drawn map accompanied a report from surveyor Abel de Vries on the condition of the dikes along the Merwede river in the Land of Althena. The map was part of an effort to visualize disaster mitigation strategies in the aftermath of the 1726 Flood.

In fact, no mention was made of shipworms in the notes of the Statenvergadering through December 1731, even after they had been discovered in other parts of Holland!

The notes of the Statenvergadering are not the only source of information about the institutional management of water, however. The resolutions of the Estates General of Holland are a treasure trove of information. Intermixed with terse, economical notices of import restrictions, subsidies for the herring fishery, and official appointments of individuals into the bureaucracy of Holland are numerous extended reports (including correspondence, notes, and maps) of water and disaster management.(2) Perhaps this rich source of information could resolve this situation, but I would have to travel to Amsterdam to find it.

Also called the “spekkoek” for its visual similarities to the Dutch-Indonesian layer cake, the city archives of the Netherlands are housed in the Gebouw de Bazel, a Rijksmonument.

The Stadsarchief (city archive) of Amsterdam is a wonder of the archival world. Housed in the fantastic “De Bazel” building (a Chicago-style Rijksmonument on its own, built in the early 20th century), it is also one of the most well organized, digitally accessible archives I’ve ever used. Their comprehensive collection of the printed resolutions of the Estates of Holland (complete with indexing, thankfully), I expected, could offer quick insight into this problem.

Indeed, a resolution on the 10th of April 1728 noted the necessity of inspecting Goeree because “the earlier inspection is now already two years old, and in the meantime, the state of the island and the course of the current and the depths could be notably changed.”(3) The “provisional report,” however, would only arrive in 1732. An inspection at the beginning of July 1732 noted “all of the pileworks on the south side of the island are infected by the shipworms.”(4) This is the smoking gun and one that had not appeared previously in the literature. Judging from the subsequent descriptions of the mollusks in the provisional report (similar in language and detail to the “first impressions” of the shipworm elsewhere), this was likely their initial encounter. Goeree may have experienced shipworm damage at an earlier date, but this was likely the first official account in Holland. Thus, the more established historiography dating the shipworm outbreak to Zeeland seems to hold. Considering the fact that it was the Zeelandic accounts dating to 1730 that would later circulate in West Friesland rather than from Goeree (part of the same province), it makes sense that shipworms would have appeared later in the island’s records.

2. A second goal of the trip was to find new datasets for cattle plague numbers and mortality between 1769-1780. This information is necessary for a collaborative project between Filip van Roosbroeck and myself. The core question of our study is to determine why some regions of the Netherlands were more strongly impacted by the cattle plague epidemics than others.

The Historisch Centrum Overijssel has the added benefit of being located in scenic Zwolle.

Our original ambition was to compare regions in Flanders (Van Roosebreuck’s study area) with those of comparable regions in the Netherlands. Based on Filip’s prior work on the Austrian Netherlands, his hypothesis was that market-oriented regions (typically coastal areas) would have greater susceptibility to the outbreaks, whereas areas with less market-driven use of cattle (for instance, in the production of fertilizer and/or small-scale dairying) would be less susceptible. For this reason, I traveled to the cities Arnhem and Zwolle to find out whether their archives contained useful data series (either from mortality records or tax records on number of cattle, called hoorngeld). Our intention was to compare these eastern regions with coastal Holland and Friesland. This approach was derailed for several reasons. Firstly, because colleagues suggested that the Netherlands and the Austrian Netherlands (now Belgium) were not overtly comparable in their market-orientation or their environments. Second, I quickly discovered that the necessary data simply does not exist from the regions of the Overbetuwe (in Gelderland) or Twente (in Overijssel). As a result, we reformulated our hypothesis to address a similar question, albeit with a more tightly defined scope. What explains the regional variation within the province of Holland?

Holland is an ideal study area because of the richness of its records.

The Alkmaar Cheese Market. Alkmaar has had an operational market for centuries and the first cheese “scale” in the weigh house dates to the 14th century.

The province required municipalities to produce data series noting the number cattle infected, killed, and recovered. Despite having already collected a fairly detailed account of cattle mortality on previous research trips in Holland, we still had a small amount of archival research to do. An important subset of years at the outset of the epidemic in the early 1770s was completely absent from our records. Luckily, the Regionaal Archief Alkmaar had comparable records (though in a slightly different format). This archival visit had the added benefit of being on a Friday. Alkmaar holds their famous kaasmarkt (cheese market) Friday mornings during the summer. Although incredibly touristy, the cheese market hearkens back to the significance of this part of Holland in the early modern dairying economy. The Alkmaar kaasmarkt has a rich tradition and it’s located in the middle of an incredibly scenic, well preserved city center, but it was impossible on this particular day to observe the event without thinking about how dramatically the rinderpest epidemics of the eighteenth century would have affected this area. The research trip was successful. Having collected the data, we can now move forward with analysis. We plan to focus on the Gooi area and possibly the environmentally/culturally unique riverlands to the south, though the data and available literature will likely dictate our final decision.

3. My final (and largest) goal was to collect archival material and conduct preliminary secondary research on a river-flooding project. This was my most pressing assignment. Not only will this work be part of a collaborative research article with Toon Bosch, but I will also likely present the results of this research at the Annual Meeting of the American Historical Association in 2017 and possibly use this as the core of a final chapter for my manuscript. Aside from getting a sense of the scope of the floods and learning the history of the Dutch Rhine and Meuse (see blog), I was interested in the intersection between climate, flooding, and institutional management of the rivers in the 18th century. To what extent did river flooding in the Netherlands change in scope or severity? Did contemporaries recognize any shift and did they connect this to environmental changes? How did institutional management strategies adapt to any changes?

The floods of the 1740s run counter to the prevailing long term trends in river flooding. It should be noted that this graph notes frequency, not severity. Contemporaries of these floods felt that floods had been getting worse, not necessarily more frequent. Source: Glaser et al. “Historical Floods in the Dutch Rhine Delta,” Natural Hazards and Earth Systems Sciences (2003), 608.

Although still early in the process, my research has already yielded some surprising results. The floods of 1740-41 (which are my primary interest) were rather unique in origin. The floods did not occur during a period of increasing river flooding on a continental scale. Environmentally, one could even argue they were flukes. Unlike many of the river floods of the 18th and 19th centuries, these were NOT the result of ice dams. Ice dams occur when frozen sections of the rivers block discharge resulting from quickly melting snow pack (often coinciding with heavy rainfall). Ice in the lower reaches of the rivers block the discharge, forcing water over the dikes resulting in breaches. River flooding along the Dutch Rhine and Meuse are complex beasts, however, and not all floods followed this formula. This is partly because the rivers themselves are quite different. The Meuse is rain fed; whereas the Rhine’s discharge depends on both precipitation and snow melt in the Alps. The floodplains of the Rhine and Meuse interact closely in South Holland and Gelderland, but massive inundations require concurrent extreme events in the upper reaches of both river systems. The final piece of the puzzle is the human interactions with the river systems. Over the course of the early modern period, the human element would gain in relative significance. The steadily shrinking lands outside the dikes (because of drainage and peat excavation), coupled with increased sedimentation over the course of centuries necessitated increasingly higher dikes in a classical technological lock-in scenario. When a heavy rainfall event like that which occurred during the winter of 1740-41 occurred, dike breaches could occur in multiple locations.

The response was swift, but not coordinated. Cities were largely responsible for rescuing citizens in their hinterlands (a management strategy codified following the disastrous 1726 floods in the same region). Cities struggled to cope with their own inundations in the 1740s, however. Woudrichem and Heusden, for instance, were also inundated and did not have the capacity to extend help to their hinterlands. The Staten van Holland, meanwhile, offered subsidies, but no direct support. The floods of 1740-41 are well known for being the first flood recovery financed partly from citizens outside the affected regions, but help was belated and could not compensate for the extensive damages.

The final page of a special commission report on the states of dikes following the 1741 floods. The report was conducted by Willem Jacob s’Gravesande and Melchior Bolstra.

The most significant response on the part of the provinces came in the form of advisory commissions established to investigate flood vulnerability in the riverlands. The same cast of characters employed to assist in the repair of the West Frisian dikes (and previous river floods) were once again asked to lead the “scientific” investigation into the disaster. The Leiden professor Willem Jacob ‘s Gravesande and the surveyor of Rijnland Melchior Bolstra presented a report on the 24th of January 1741 detailing their suggestions. They suggested lowering the dams of the creeks to ease the pressure on the main channel, but to also encourage increasing streamflow to the sea. Their advice was the first in a protracted battle between the provinces and cities in the floodplains of the Rhine and Meuse. Despite intense interest and significant resources dedicated to the study of the river system, significant technological adaptation would be delayed until the 19th century. In the meantime, the Dutch would endure over a century of intense river flooding.

This is just one small part of the larger story of societal response and environmental change in the mid 18th century. Although the flooding seems environmentally disconnected from larger continent-scale climate changes and resulting increases in river floods, they were VERY connected to larger scale cultural and social vulnerabilities. This is not the place to outline a complete argument (especially since I have only begun developing it), but suffice to say that Dutch vulnerabilities increased during the mid-18th century largely due to political, economic, and social conditions rather than climatic factors. Social and political conflicts arising from the unique forms of “wet system building” established in the Netherlands created conditions conducive to short term adaptation, but not coordinated river management. (5) Communities tasked with maintaining dikes and provinces tasked with clearing stream-beds seemed perpetually at odds with one another and both suffered from lack of resources. Climate and society always participate to some degree in the causal dance of river flooding. The challenge for the future of this project will be to tease out their relative importance.

Although my research this summer has primarily focused on these three broad subjects, small side projects and trips occupied significant time as well. The products of several of these detours can be found in earlier blog posts. At the same time, one cannot research every day (archives aren’t open on the weekends after all…) Bike trips through the river valleys of the Meuse (in Limburg) and the Waal (in Gelderland) and the polder landscape of Leiden were fascinating introductions to landscapes I could only otherwise read about.

A vision of the boezem collecting and storing pumped polder water for eventual discharge into the Rhine. This photo was taken while biking with environmental historian Petra van Dam through the farmlands to the south of Leiden.

Donald Worster once advised my cohort of graduate students at KU to “get our boots muddy.” Environmental history, he reminded us, was first and foremost grounded in material places. It’s dirt, water, fungus, and worms. History is found in these elements just as much as it is found in centuries-old dike reports, maps, and government resolutions. I’ve done my best this summer to utilize both sets of information. I’m currently writing this final post sitting in a train heading back to The Hague. It’s a dreary, rainy day in the Netherlands and my boots are sodden. The rainwater has largely washed off whatever mud they had collected over the last month and a half. When I fly out tomorrow, I may not be bringing the literal “dirt” of environmental historical work back with me, but that’s only partly what Don meant anyway. The mud is just what you pick up along the way. It’s a reminder of the journey. What I’m bringing back is much richer.

Shipworms in the news!

Door de paalworm glooit de dijk

In 1730 brak aan de Nederlandse kust een paalwormepidemie uit. De zeedijken bestonden toen veelal uit palenrijen, waarachter wier- of zeegraspakketten de aarden dijklichamen beschermden. Van Zeeland tot Friesland werden de palen door paalworm aangevreten. Hoe hebben de Nederlanders gereageerd op deze voor hen ongekende ramp, die het uiterlijk van het kustlandschap blijvend zou veranderen?

Post 3/3 – Disasters were all connected

In post 3/3 of my series on unusual connections, I want to broaden the scope my argument beyond simply river floods and shipworms. Disasters in the Dutch 18th century were all connected!

In a sense, this is the principal argument of my manuscript. The eighteenth century was (relatively) disastrous for the Dutch Republic.(1) After enjoying a century of prosperity, the Golden Age of Dutch economic success, artistic efflorescence, and political influence had begun to wane by the eighteenth century. Disasters reflected new anxieties about this change of circumstances just as they contributed to increasing financial pressures.

An anonymous pamphlet detailing the terrible consequences of the “hard winter” between 1739-1740. Anon. Een historiesch verhaal van veele en nooit meer gehoorde voorvallen, die geschiet zyn in verscheide harde winters, inzonderheid van den jaare 1709. en 1740

Natural disasters were certainly not new to the eighteenth century and there is no indication that they increased in number between 1650-1750, but the reaction to them shifted.(2) Natural disasters unearthed buried social tensions, prompted providential reevaluations, and produced intense reconsideration of the Dutch relationship with their environment. (3)

In this perfect storm of cultural, economic, and environmental uncertainty, contemporaries linked disasters together. Naturally, causal connections were stronger in some situations than others. Adverse weather, particularly harsh winters like 1740-1741, created numerous rippling effects and directly or indirectly contributed to several other demographic and environmental disasters. In addition to the direct consequences of frigid conditions (reports of cattle and sometimes even people dying from exposure abound), historians have indirectly connected adverse weather to a widespread mortality wave in the Netherlands and across Europe via failed harvests. (4) Furthermore, frigid conditions prompted the formation of ice dams on Dutch waterways. One can even connect these stressful environmental conditions to cattle plagues. Lack of fodder and prolonged exposure to adverse conditions likely weakened the immune systems of cattle making them more susceptible to disease. Rivers, on the other hand, had very little direct causal connection to the shipworm epidemic outside of the circumstances mentioned in these post.

Independently of direct environmental causation, however, contemporaries discursively linked the disasters of the 18th century. Rural communities merged disasters together in their petitions for remission from provincial taxation. The burden of rebuilding dikes in the wake of river floods (or shipworms) combined with the need to replenish cattle stocks after cattle plague epidemics) while also shouldering their usual tax burden, residents argued, was untenable.

The most common discursive linkages were providential. Disasters pointed to God’s wrath and confirmed the sinful state of the Dutch Republic. Clergy and laypeople discursively connected disasters in order to build a case for providential causation. Each successive disaster was further proof of this “sin economy.” Causal stories grounded in divine providence were far from uniform and they could be tailored to suit any numbers of agendas. Providential readings of disasters could challenge or support political ideologies, promote or discourage technological adaptation, or inspire emotional connection to disasters victims. (5) Regardless, repeated disasters like that of the shipworms epidemic and the mid-century river floodings strengthened these interpretations.

Finally, water authorities likewise created discursive connections between disastrous events, in particular river flooding and coastal flooding. This was very apparent in the 1730s during the shipworm epidemic and in the wake of disastrous river floods along the Rhine in 1726 and 1740-41. By the 1740s, paranoia about the breaking of the northern Lekdijk had become fever pitch. (6) The 1740-41 floods were not incredibly deadly but they were extensive. By the 1750s, it seemed almost a miracle that the northern Lekdijk, which protected much of the Green Heart of Holland, had not yet broken. Water authorities like Velsen were deeply cognizant of the vulnerability of the economic center of the country to flooding if the northern dike along the Lek fell. If that were to happen, the entire area between the river lands and the river IJ near Amsterdam could be inundated.

At the same time, flood vulnerability was becoming an object of increasing concern in northern Holland. By 1733, West Frisian water boards had shifted the discourse surrounding shipworms from a novel biological disaster (for which there was still no adequate response) to the more manageable threat of coastal flooding.

The title page of a pamphlet that collected dike reports and advice from the West Frisian water authorities. The West Frisian sea dikes must be “a barrier against the sea for the entirety of Holland, and must also be used as a fortress that protects the entirety of Holland” – Seger Lakenman 12 Jan, 1732

If the West Frisian sea dikes failed, the water boards argued, the “fortress” of northern Holland (in particular the “Westfries Omringdijk) from West Friesland south to the IJ could be turned into a “bare sea.” The vulnerability discourses of North and South Holland were complimentary and even shared the same language. Should these disasters occur simultaneously, Holland would face an existential threat. Both Velsen and the designers of the new shipworm-proof sea dikes of West Friesland harnessed this discourse to their advantage, though Velsen would enjoy far less success in realizing his proposals.

Although the shipworm epidemic of the 1730s and the river flooding between 1726 and the 1750s seem to have little in common, closer inspection reveals numerous connections. In this series of posts, I’ve highlighted three connections, but this only scratches the surface of possible relationships. Governing governing bodies sometimes used disasters management efforts as political tools to further their own, more local interests. For instance, several cities along the Meuse river blocked a subsidy for the repair of West-Frisian sea dikes during the shipworms epidemic in 1735 in order to push through their goals. One of the consequences of the increasing consolidation of water management under the provinces was that the disaster management needs of one region could become beholden to those of another.

It should perhaps come as no surprise that disasters beget other disasters. Scholars often focus on direct causal relationships stemming from persistent social or economic disadvantage, environmental (oftentimes climatic) influence, or poor management of infrastructure to explain these relationships. These connections were likewise influential in the early modern Dutch Republic. The increasing consolidation and integration of large scale water management in Holland as well as the province’s growing reliance upon “expert” advice in the eighteenth century ensured financial and technological relationships between seemingly disconnected disasters. At the same time, contemporaries crafted discursive relationships between disasters separated by years (even decades) in their ambition to create disaster mitigation strategies and  to lessen the financial burden of the events. Providential interpretations used a similar strategy in order to promote moral interpretations and responses to these periods of disaster.

“Unlikely connections” were not limited to the relationships between shipworms and river floods either. One could just as easily tally off similar connections between shipworms and coastal flooding or cattle plagues. The nature of disaster interpretation and management in the Dutch eighteenth century would seem to have facilitated many of these relationships. A compelling argument might also be made, however, that this was not a condition of pre-modern disasters. Disasters are still frequently linked together, causally, institutionally, and discursively. Scholars should certainly not abandon seeking environmental or social relationships between disasters, especially in the early modern period, but many other types of connections (cultural, moral, technological, political) abound as well.

(2) Indeed, there is little reason to believe that river floods or storm surges increased in number over the course of the 18th century, though there is some indication that they increased in severity. The shipworm epidemic and cattle plagues were exceptions in that they certainly increased in severity and number.

Dutch River Flooding 1740-41 – Carto/ArcGIS Online/Mapbox

For some time, I’ve been trying to find good workarounds to host and display geotiffs of historical maps. There are a number of options available, from Neatline/Omeka to Google Earth, to Maptiler/google hosting, to arcgis online. Unfortunately, most have significant disadvantages. Google Earth will display the geotiff as a background, but there is limited interactivity with vector data. Maptiler requires a paid account to remove its watermark and the google hosting option will likely disappear as an option this year. ArcGIS online requires access to an arc server. Depending on the size of the project, Neatline/Omeka is a good option if you have the space to host it on your own server, but its installation is not particularly user-friendly. The most intuitive option I’ve found thus far has been Mapbox. An online map styling platform that offers a GB of hosting space for free accounts, Mapbox provides a user-friendly GUI (much improved from the TillMill/Maptiler classic, though with more limited raster manipulation options) and easy integration of your Geotiff basemaps with ArcGIS Online, CartoDB, Leaflet, or simply hosting static images on your own website. Naturally, I’m sure there are a number of additional options and I’m very interested to hear suggestions and/or see examples using different methods/platforms.

Below, I’ve attached two options using a small dataset that visualizes dike breaches throughout the Rijn/Maas river region of the Netherlands during the catastrophic floodings between Dec 1740 and Jan 1741. The first is an animated “torque” map that highlights the location and timing of dike breaches. The second in Arc Online is an interactive, albeit static map that features additional information about the dike breaches (location, time of day, source of information, and the regions the breach threatened).

One issue I’ve noticed with this hosting option is that higher zoom levels distort the historic basemap. As you zoom in, the basemap resolves more clearly. I have yet to find a work around for this issue.
