All-Russian Congress of Soviets

The All-Russian Congress of Soviets was the supreme governing body of the Russian Soviet Federative Socialist Republic from 1917–22 and of the Soviet Union until 1936. The 1918 Constitution of the Russian SFSR mandated that Congress shall convene at least twice a year. The 1925 constitution lowered the minimum to once a year. The October Revolution ousted the provisional government, making the Congress of Soviets the sole, and supreme governing body.
