The Frankfurt Auschwitz trials, known in German as Der Auschwitz-Prozess, or Der zweite Auschwitz-Prozess, was a series of trials running from 20 December 1963 to 19 August 1965, charging 22 defendants under German criminal law for their roles in the Holocaust as mid- to lower-level officials in the Auschwitz-Birkenau death and concentration camp complex. Hans Hofmeyer led as Chief Judge the "criminal case against Mulka and others".

West Germany was the Federal Republic of Germany from its formation on 23 May 1949 until its reunification with East Germany on 3 October 1990. During the Cold War, the western portion of Germany and the associated territory of West Berlin were parts of the Western Bloc. West Germany was formed as a political entity during the Allied occupation of Germany after World War II, established from 12 states formed in the three Allied zones of occupation held by the United States, the United Kingdom, and France. The capital was the city of Bonn, hence the Cold War-era country is sometimes known as the Bonn Republic.
