Towards the autumn political stability continued to shake, and countering the rising nationalist tendencies were the Bolshevik Soviets, when the October Revolution hit Russia, that same day, on 25 October (7 November), the Minsk Soviet of workers and soldiers deputies took over the administration of the city. The Bolshevik All-Russian council of Soviets declared the creation of the Western Oblast which unified the Viĺnia, Viciebsk, Mahilioŭ and Minsk guberniyas that were not occupied by the German army, to administer the Belarusian lands in the frontal zone. On 26 November (6 December), the executive committee of workers, peasants and soldiers deputies for the Western Oblast was merged with the Western front's executive committee, creating a single "Obliskomzap". During the autumn 1917/winter of 1918, the Western Oblast was headed by Aleksandr Myasnikyan as head of the Western Oblast's Military Revolutionary Committee, who passed this duty on to Karl Lander. Myasnikyan took over as chair of the Russian Social Democratic Labour Party's (RSDRP(b)) committee for Western Oblast and Maisiej Kaĺmanovič as chair of the Obliskomzap.
