The Makhnovshchina is established.

The Makhnovshchina was a mass movement to establish anarchist communism in southern and eastern Ukraine during the Ukrainian War of Independence of 1917–1921. Named after Nestor Makhno, the commander-in-chief of the Revolutionary Insurgent Army of Ukraine, its aim was to create a system of free soviets that would manage the transition towards a stateless and classless society.
