Abstract
This article examines proto-industrialization and the social relations of production in a rural parish in eastern Westphalia that experienced large-scale outmigration to the American Midwest in the mid-nineteenth century. Relying on local and individual-level Prussian tax and emigration records, the study identifies and analyses the socio-economic background of the migrant cohort in terms of proto-industrial activity and peasant economy. Preceded by the downfall of domestic textile industries due to British industrial competition, outmigration was highly selective, drawing individuals from specific socio-economic niches. Landless sharecroppers - linked by debt and labour obligations to better-off peasants and landlords - were underrepresented in the migration, while smallholding peasants and day-labourers - 'free' to commodify their labour power through the sale of home-produced textile products or seasonal migratory labour - were overrepresented. The findings of the study have implications for an understanding of the localized nature of the relations of production in proto-industrial regions, the historical nature of German emigrations, and the dynamics of the German transition to industrial capitalism in the nineteenth century.
