Migration and racism are major topics in the histories of Germany and the United States during the twentieth century. The two phenomena occurred in a wide variety of forms, often being shaped and perceived in rather different ways in the German and the American setting. This also holds true for the post-Nazi, the post-colonial, and post-segregationist eras: they did not bring an end to forms of racism that evolved in the numerous ways in which migrants were othered and racialized on both sides of the Atlantic, in Germany (East and West) and the United States. This workshop invites historians and other scholars of racism and migration to revisit these topics in the context of German and American history in the twentieth century. The workshop aims to focus on the various ways in which migration and racism have shaped each other. By juxtaposing German and American phenomena that reveal how migration and racism were entangled or mutually constitutive, the workshop furthermore seeks to explore transatlantic connections. Analyzing these interlinkages might suggest the extent to which German and American racism and attitudes toward migrants and migration have a common history.
