The chapter attempts to shed light on the history of Turkish migrant women’s left feminism in West Germany, particularly focusing on the case of Women’s Union in the Ruhr-Gelsenkirchen (GKB), which was active from the mid-1970s until the beginning of the 1990s. The chapter analyzes how Turkish migrant left feminism in West Germany contributed to women’s activism in Europe and Turkey, and how including migrant women’s organizations in the research changes the understanding of women’s transnational activism in the Cold War context in general. The historical analysis of Turkish migrant feminism is framed by the concept of “political generations.” “Generation” is adopted as an analytical category that does not essentially rest on fixed entities such as age; instead, it is used as a historical concept that corresponds to the effects of wider social, cultural, and political processes on the political organizing of Turkish migrant women in the European Cold War context.
