Policies excluding ethnoracial and religious minorities reinforce the power of political elites. This study addresses an extreme case of exclusion: urban expulsions of Jews in the medieval western Holy Roman Empire. Expulsions were official edicts proclaimed by Christian princes, lords, or town councils, whomever ruled a territory. Changing religious and political culture, in the form of new value on community righteousness and the beginning of territorialization, provided incentives for polities to expel their Jewish residents. Using a new database of Jewish settlement and city development in the Western Holy Roman Empire 1000–1520 CE, I show that the relational structure of political power between Christian elites could insulate or expose Jewish communities to political contests of the time. Jews were derided, lesser members of Christian society, but in spite of increasing focus on Christian piety and legislating community purity, most cities did not expel their Jewish residents. City rulers that did expel were attempting to solve challenges for sovereignty through their policies toward Jews.

The historical-comparative study of social democracy and cooperative organization are the foster children of historical sociology. This article offers a first account of systematic ideological differences in social-democratic ideology regarding private ownership and different cooperative traditions in the housing sphere of Northern European and continental German-speaking countries. The long-run trajectory of housing welfare regimes in these two country groups has been one of divergence: Nordic countries have moved to Anglo-Saxon levels of high homeownership, high levels of mortgage indebtedness, and house price increases, whereas private tenancy, lower indebtedness, and lower price increases still characterize their German counterparts. Based on historical case studies of Germany and Norway, we argue that the divergence in these two countries can be understood by the different social-democratic and cooperative solutions to the urban housing question from the 1920s onward. Supported by a pro-ownership social democracy, Norway started to develop housing cooperatives of the owner cooperative type, whereas German social democracy was in favor of associations of the tenant cooperative type. The differential growth of these two types of cooperatives and disparities in social democratic party ideology contributed to the urban housing divergence between the two country groups that has been observed ever since. We argue, more generally, that varieties of social democracy and welfare-anticipating cooperative organizations are important in helping us understand the welfare differences between countries.

In contrast to most long-settled agricultural landscapes, the US Great Plains presents a rare example of well-documented agricultural colonization of new land. The Census of Agriculture provides detailed information about evolving grassland farm systems from the beginning of agricultural expansion and then at some two dozen time points between 1880 and the present. From early sod-busting, through drought and depression, and into late-twentieth-century modernization, it is possible to track how farmers used their land in any county. Treating farmland as an agroecosystem, a hybrid human-natural landscape, this article asks how farmers captured, altered, and replenished soil fertility. Did they extract more soil nitrogen than they returned, or did they maintain a balance? The article assesses land use from a soil nutrients perspective in several plains environments to capture variation in climate (especially rainfall), native soil quality, and availability of irrigation water. It traces farm management strategies through time to understand agricultural crises, growth periods, and technological transitions in the context of soil fertility. Soil management on an agricultural frontier was markedly different from that in places that had been farmed for centuries. A shortage of people and livestock and an abundance of deep, rich soils in the plains informed farmers’ calculations as they juggled labor, capital, and market forces against family and financial strategies. Uniform methods of estimating and representing soil nutrient processes make possible a direct comparison of the relative sustainability of historical agroecosystems.

This article delves into the processes of territorial transformation by foregrounding the material dimension of infrastructure. The entry of the research is infrastructure network design and planning. We will trace the concepts of territorial transformation inscribed into the material layout of large technical systems by analyzing the discourse of engineers and policy makers involved in the conception of infrastructure networks. In so doing, the material politics of infrastructure networks will be studied: How did engineers and policy makers design infrastructure to generate a specific territorial transformation? Moreover, how did technological plans hold the idea that one could influence modernization processes by means of a territorial transformation instigated by infrastructure? The neutral status of technology is thus fundamentally challenged by showing that engineers, in association with policy makers, were essential actors in the planned transformation of the territory as they organized infrastructure networks according to specific ideas relating spatial and societal transformation. The article focuses on two decades after the independence of Belgium (1831), when engineers conceived comprehensive networks of rails, waterways, and roads. The material politics of two major public works initiatives will be analyzed: (1) the centrally positioned railway network that connected all industrial centers within the territory as well as with the markets of neighboring countries, positioning Belgium into Europe as international turntable, and (2) a network of roads and canals in peripheral, so-called unproductive, regions that had to integrate these regions within national borders, and indeed extend these borders, as well as buffer and govern the side-effects and risks generated by the accelerating industrialization in the central parts of the nation.

Using a socioecological metabolism approach to analyze data from the Census of Agriculture, this article examines the underlying soil fertility of two case study areas in the Canadian province of Saskatchewan through the calculation of soil nitrogen balances. The Rural Municipalities of Wise Creek and Livingston are 300 miles apart and therefore have different topography, soil types, and rainfall levels, even though both are within the northern Great Plains. Over 85 years, from first settlement in the 1910s until the beginning of the twenty-first century, Wise Creek agriculture focused increasingly on livestock production while in Livingston farmers began to grow a greater variety of crops, most notably incorporating canola into rotations. Despite the differences between the two case studies, the pattern of soil nitrogen losses was remarkably similar, with biomass yields declining along with soil nitrogen. The addition of chemical nitrogen fertilizers since the 1960s did not produce yields matching historic highs, nor did a renewed focus on livestock. Wise Creek and Livingston showed two different responses to declining yields, but neither one ultimately provided a long-term solution to the problem of soil nutrient depletion and consequent productivity declines.

This article investigates the Ili Rebellion in Xinjiang (1944–49). Relying primarily on Chinese sources, the author identifies variations in the rise and fate of non-Han ethnic guerillas, and the patterns of military conflict in different regions during the expansionist stage of the Ili Rebellion from 1944 to 1946. The article argues that neither a nationalist nor a geopolitical explanation adequately account for such variations. Rather, the overlapping and intersecting geopolitical influence (both the Soviet Union and the two Chinese regimes) as well as local conditions (including local ethnic composition and social structure) explain such patterns. Finally, this article discusses broader implications of the role of nationalism and geopolitics in revolutions in small and dependent states.

The state executions of 81 IRA men during the Irish civil war have long been a bitter, almost taboo subject in Irish society. This article provides a geographical perspective on these executions. While the origins of the policy can be traced to elite divisions, the geographical spread of the executions, especially in 1923, reflected the geography of the civil war, and the need to broadcast state power at the local level during its guerrilla phase. The article maps the geographical spread of the executions and analyzes their diffusion in terms of a number of general and Irish-specific theories of civil war violence. Because the civil war originated in elite differences over a treaty, and because the two sides of the conflict had been so personally close at the elite level, historians have tended to explain the executions in terms of elite psychology. Yet while the initial development of the policy reflected the centralization of power by the protreaty elite, in terms of timing, strategic rationale, and location territorial perspectives on civil war explain much more about their diffusion in 1923.

The initial period of construction of the Spanish railway network is often criticized for its radial structure, centered on Madrid. In this article, the authors describe the role of the state during the initial stage of railway network construction and confirm that although the political will to construct a centralist network certainly influenced its morphology, other social and economic criteria were also influential. With regard to the political motives behind the radial network, the authors argue that part of this interest could have come in response to perceived needs to strengthen the presence of the Spanish state throughout its national territory and to promote a process of state-building. Finally, it must be stressed that the central hypothesis of our article is that the radial structure of the network was a natural consequence of the strategic geographical position of the country’s capital and of the distribution of economic activity within Spanish territory. The article proposes two methodological approaches for evaluating the extent to which the radial design of the network was justified, bearing in mind the locations of Spain’s most productive regions. The results of these two exercises suggest that the radial configuration with which the Spanish rail network was originally designed probably arose naturally as a result of the distribution of economic activity within the country and of the relative advantage that this bestowed on certain regions due to their geographic position.

Fertile soils are essential for human health and nutrition and formed the foundation of human economies for millennia. Soils deserve close attention from environmental and economic historians and sustainability scientists. Most soil history literature addresses failure: misuse of soil, uncontrolled erosion, and the resulting collapse of past civilizations. More important, however, and of urgent interest for our present and future prosperity, are the mundane ways that historical farm communities sustained soil health, even while cultivating the same land for centuries. This article explains five strategies by which European and North American farmers accessed, recycled, replenished, and sustained soil fertility over 250 years. By evaluating inputs, extractions, transfers, and annual balances of potassium, phosphorus, and, especially, nitrogen, it models historical soil management in a variety of agroecosystems in various geographical settings and through time. This biophysical environmental history, based on socioecological metabolism methods borrowed from sustainability science, reveals ongoing adaptation to shifting social and environmental contexts. As industrialization, global trade, and population accelerated, farmers adjusted their soil fertility strategies to keep up with new pressures and opportunities. Each solution to existing soil fertility constraints created new obstacles and bottlenecks. Through the past quarter millennium, farm sustainability meant constant readjustment to new circumstances. As farmers innovated crop choices and rotations, corralled livestock, adopted new technologies, deployed novel energy sources, and expanded into new lands, they increased food productivity to feed growing world population and supply expanding markets, while maintaining the supply of soil nutrients necessary to fertilize next year’s crop.

In 1850, after three decades of political turmoil, Portugal started investing in major public works, particularly, in the construction of a national railway network. This strategy followed closely the suggestions of the Saint-Simonian technocrats with whom Portuguese engineers had been engaging since the 1820s. Additionally, it came in response to the longtime neglect suffered by the Portuguese transportation system, which hindered communications and trade between different areas of the kingdom and with neighboring Spain. The main goal of the investment was to modernize the national transport system, attract to Portuguese harbors a large portion of the traffic between Europe, Africa, and America, and, in general terms, put the nation on the path of progress. By the end of the nineteenth century, total mileage of the Portuguese rail network exceeded 2,300 km. This article analyzes the role of railways in the improvement of communications between the Portuguese provinces, their appropriation in a unified nation-state, the degree of integration of the Portuguese economy with the Spanish and European economies, and the construction/reinvention of Portugal as a modern and technological nation. To achieve these goals, I will use three key concepts: territorial appropriation, circulation, and globalization. Sources include statistics of railway operation and previous works analyzing the impact of railways on the Portuguese transport system and economy, the outcomes of operating transnational lines, and the importance of technology for the reinvention of Portugal during the second half of the nineteenth century.

Four synchronous epidemics of measles and scarlet fever are observed in the historical data collected by colonial authorities in Victoria, Australia from 1853 to 1876, suggesting some sort of synergistic relationship between the two diseases. While epidemics of measles, as recorded by the colonial record keepers, still occurred during the remainder of the study period (until 1916), no further epidemics of scarlet fever occurred after 1876. This is suggestive of a change in Victoria’s disease ecology in the late 1870s. After analysis of the historical data for potential artifactual cases, it does not appear to be the result of confusion in diagnosis and changes in case definitions do not appear to have affected reporting of the causes of death. We conclude that the most likely explanation for the observed pattern is an epidemic synergy that ended after the 1876 epidemic. We hypothesize that this synergistic relationship between measles and scarlet fever in mid-nineteenth-century Victoria ended due to a shift in the dominant group A streptococci (GAS) M-type or the loss of a GAS bacteriophage. Support for this hypothesis comes from observations that other diagnoses associated with group A strep infections also changed their mortality profiles during the 1870s, particularly “Bright’s disease,” a possible descriptor of post-streptococcal glomerulonephritis. We situate the emergence and end of this pattern within the demographic and socioeconomic conditions of the Victorian gold-mining boom in the 1850s to 1870s and postboom changes in fertility, mortality, and housing infrastructure, highlighting the importance of social conditions in disease evolution.

Barry Eidlin’s book, Labor and the Class Idea in the United States and Canada (Cambridge University Press, 2018) explains why unions are weaker in the United States than they are in Canada, but have not always been that way. Indeed, unionization rates were virtually identical for much of the twentieth century, then diverged in the 1960s. Against dominant accounts focused on long-standing differences in political cultures and institutions, Eidlin argues that the divergence resulted from different ruling party responses to working class upsurge in both countries during the Great Depression and World War II. In Canada, an initially more hostile state response ended up embedding “the class idea”—the idea of class as a salient, legitimate political category—more deeply in policies, policies, and practices than in the United States, where class interests were reduced to “special interests.” In this symposium, three noted labor scholars engage critically with the book. Cedric de Leon interrogates Eidlin’s account of the role of racial divisions in explaining divergence, noting “more persistence and convergence than there is rupture and divergence” between these two countries on this issue. Nelson Lichtenstein’s critique focuses on the exceptionally vociferous character of US employer hostility, which he argues that Eidlin downplays. And Judith Stepan-Norris notes the surprising lack of actual class actors in a book about class organization, while raising interpretive questions about the relation between labor and the Communist Party in both countries. Eidlin concludes the symposium with a response to the critics.

What social conditions produce positivism? One position, common to both positivists and some of their major critics, suggests that positivism is an “ideology” or “worldview” of industrial capitalism. Positivism therefore resonates with the basic experience of capitalism for all social groups. Intellectuals draw on this experience in formulating positivist social science. A second position suggests that positivism is a strategy of distinction by which intellectuals attempt to accumulate symbolic capital against their rivals. This position suggests that positivism is a resource for establishing a social science that imitates the methodology of natural science. Our article argues for a third view focused on the internal structure of the intelligentsia as a social group. Positivism could emerge in both industrial capitalist and preindustrial contexts; however, the types of positivism differ in these two cases because the structure of the intelligentsia differs. In preindustrial contexts, such as nineteenth-century Italy, which is the focus of our analysis, positivists claim an ontological continuity between natural and social sciences. In industrial contexts, on the basis of which most theories of positivism rest, positivists claim a methodological similarity between natural and social sciences. We conclude our analysis by reflecting on the implications of our study for work on positivism and social ontology in the social sciences.

We study the relationship between internal migration and industrialization in the United States between 1850 and 1880. We use the Linked Representative Samples from IPUMS and find significant amounts of rural-urban and urban-urban migration in New England. Rural-urban migration was mainly driven by agricultural workers shifting to manufacturing occupations. Urban-urban migration was driven by foreign-born workers in manufacturing. We argue that rural-urban migration was a significant factor in US economic development and the structural transformation from agriculture to manufacturing.
