All-Russian Congress of Soviets
The All-Russian Central Executive Committee was first elected at the First All-Russian Congress of Workers' and Soldiers' Deputies' Soviets, held in Petrograd, June 3–24, 1917. The first Central Executive Committee of the All-Russian Congress of Soviets was not a governing body and its chairman Nikolai Chkheidze was not the head of Russian state. This changed at the Second All-Russian Congress of Soviets during the October Revolution.
