Government of the Soviet Union
The Government of the Soviet Union (, "Pravitel'stvo SSSR"), formally the All-Union Government of the Union of Soviet Socialist Republics, commonly abbreviated to Soviet Government, was the main executive institution of government in the former Soviet Union. It was led by a chairman, but the office was commonly referred to as Premier of the Soviet Union. The premier was nominated by the Central Committee of the Communist Party of the Soviet Union (CPSU) at the 1st Plenary Session of the Supreme Soviet of the Soviet Union in the aftermath of national elections. Certain governments, such as Ryzhkov's II, had more than 100 other government members, serving as first deputy premiers, deputy premiers, government ministers or heads of state committees/commissions; they were chosen by the premier and confirmed by the Supreme Soviet. The Government of the Soviet Union exercised its executive powers in conformity with the constitution of the Soviet Union and legislation enacted by the Supreme Soviet. The first government was led by Vladimir Lenin, and the last government was led by Ivan Silayev.
