The research project “German Police Assistance in Latin America (1949 - 1989): Scope, Practices and Transnational Entanglements” analyses, for the first time, Germany's role in the modernization of Latin American police institutions and its local and transnational consequences during the Cold War. Through both a systematic analysis of documentary collections in various German and Latin American archives, as well as interviews with the actors involved and contemporary witnesses, the aim is to establish the scope of this cooperation, its practices and the processes of transnational location and interlacing of German police assistance in Latin American countries between 1949 and 1989, thus making a fundamental contribution to research on Latin America and to historical police research.
