The founding members of the CDU consisted primarily of former members of the Centre Party, the German Democratic Party, the German National People's Party and the German People's Party. Many of these individuals, including CDU-Berlin founder Andreas Hermes, were imprisoned for the involvement in the German Resistance during the Nazi dictatorship. In the Cold War years after World War II up to the 1960s (see "Vergangenheitsbewältigung"), the CDU also attracted conservative, anti-communist former Nazis and Nazi collaborators into its higher ranks (like Hans Globke and Theodor Oberländer). A prominent anti-Nazi member was theologian Eugen Gerstenmaier, who became Acting Chairman of the Foreign Board (1949–1969).
