Migration is one of the most pressing societal issues. Immigrant associations play a crucial role in understanding this phenomenon. They channel migration streams, influence the assimilation of their members, and serve as representatives of the entire immigrant group in society. However, they remain an understudied subject, particularly in historical research.

To address this gap, this study examines German immigrant associations in New York from the 1890s to the 1930s. Through an innovative combination of statistical and textual analyses, it explores the class composition of these associations, their intricate system of mutual aid, and their political activities. This study offers insights into how specific socio-economic motivations influenced immigrant organization and collective action, including aspects such as long-distance nationalism and cross-border ethnic identity.

Ultimately, based on these findings, this study demonstrates that immigrant associations played a crucial role in helping their members adapt to a new social and economic environment. Additionally, it shows why and how immigrant associations significantly shaped the image of German immigrants in American social and political life.
