The Ministry of Foreign Affairs of the Union of Soviet Socialist Republics (Russian: Министерство иностранных дел СССР) was founded on 6 July 1923. It had three names during its existence: People's Commissariat for Foreign Affairs (1923–1946), Ministry of Foreign Affairs (1946–1991) and Ministry of External Relations (1991). It was one of the most important government offices in the Soviet Union. The Ministry was led by the Minister of Foreign Affairs prior to 1991, and a Minister of External Relations in 1991. Every leader of the Ministry was nominated by the Chairman of the Council of Ministers and confirmed by the Presidium of the Supreme Soviet, and was a member of the Council of Ministers.
The Ministry of External Relations negotiated diplomatic treaties, handled Soviet foreign affairs along with the International Department of the Communist Party of the Soviet Union (CPSU) and aided in the guidance of world communism and anti-imperialism, both strong themes of Soviet policy. Before Mikhail Gorbachev became CPSU General Secretary, the organisational structure of the MER mostly stayed the same. As many other Soviet agencies, the MER had an inner-policy group known as the Collegium, made up of the minister, the two first deputy ministers and nine deputy ministers, among others. Each deputy minister usually headed his own department.
