During the Allied occupation after World War II, the city assembly (Stadtverordnetenversammlung) elected the Social Democratic politician Ernst Reuter as Lord Mayor on 24 June 1947, who, however, did not obtain the affirmation by the Allied Kommandatura of Berlin[1] due to Soviet reservations. Following the Communist putsch in Berlin's city government in September 1948 a separate city parliament (still named Stadtverordnetenversammlung von Groß-Berlin), however, de facto only competent for the western occupation sectors of what was to become West Berlin was elected on 5 December 1948, electing two days later a separate city government and Ernst Reuter Lord Mayor for West Berlin. The Soviet administration had officially deposed the previous elected government for all of Berlin with effect only in the eastern sector and had installed the SED Lord Mayor Friedrich Ebert, Jr. in East Berlin already on 30 November 1948.
