Research project:
German Racial Regimes in a Transnational Context: An Afro-German Microhistory

Research project:
The project focuses on a biographical microhistory to examine broader aspects of different German “racial regimes”-or, historically specific constellations of predominant beliefs about, and legal and political practices towards, Blacks as perceived racial “Others”-during crucial moments of the twentieth century. “Erika Diekmann” was born in Worms in the occupied Rhineland in 1920. Her mother was German. Her father was a Senegalese French soldier. Until she was eleven, Erika stayed in a Protestant children’s home in Worms. In 1931, her guardians sent her to a Lutheran school for Christian Arab girls in Jerusalem. In 1949, Erika returned to West Germany, along with her (white) German husband and their son. In 1957, she and her family immigrated to the United States. Erika died in Kentucky in 1963.
Erika’s story offers unique opportunities for situating German attitudes towards Blacks within broader international and transnational contexts. As a child of the first Rhineland occupation, Erika was the target of 1920s propaganda against the “black horror on the Rhine” (schwarze Schmach), which aimed to discredit the Versailles Treaty by falsely accusing colonial French soldiers of mass rapes of Rhenish women. “Black horror” propaganda borrowed selectively from Allied war propaganda about the “rape of Belgium” by atavistic “Huns.” The Nazis revived black horror propaganda in their murderous campaign against African French soldiers during WW II. Memories of the Weimar-era and Nazi campaigns against colonial French soldiers continued to reverberate in postwar West Germany and helped shape Germans’ encounters with African-American GIs. Erika’s biography also points to certain hitherto neglected complexities and realignments in twentieth-century German racial discourse. For instance, while Erika’s conservative Protestant mentors impressed on her the centrality of marriage and motherhood, the Nazis subjected hundreds of other Afro-German children of the Rhineland occupation to compulsory sterilization, irrevocably depriving them of the right to become parents.

Das Prinzip Donald Trump und die Verrohung der Welt

Panel Discussion, Lecture

Ein neuer Politikstil macht international Karriere. Er ist gekennzeichnet von Vulgarität, Verrohung und erklärter Rechtsfeindschaft. Machtinteressen werden nicht mehr juristisch bemäntelt. Stattdessen wird das angebliche Recht des Stärkeren zur Staatsdoktrin gemacht – innenpolitisch wie außenpolitisch. Treibende Kraft hinter dieser Verrohung der politischen Sitten ist ein US-Präsident, der nicht nur die amerikanische Gesellschaft und Kultur, sondern auch die globale Ordnung nach seinen Vorstellungen und Interessen umgestaltet. Die Römerberggespräche wollen diesen Politikstil verstehen.
