The All-Russian Central Executive Committee (Russian: Всероссийский Центральный Исполнительный Комитет; Vserossiyskiy Centralïnıy Ispolnitelïnıy Komitet), was the highest legislative, administrative, and revising body of the Russian Soviet Federative Socialist Republic. Although the All-Russian Congress of Soviets had supreme authority, in periods between its sessions its powers were passed to VTsIK. VTsIK functioned from 1917 until 1937.
