Bolshevik–Makhnovist conflict: Mikhail Frunze declares victory over the Makhnovshchina.

The Bolshevik–Makhnovist conflict was a period of political and military conflict between the Ukrainian Soviet Socialist Republic and the Makhnovshchina, for control over southern Ukraine. The Bolsheviks aimed to eliminate the Makhnovshchina and neutralise its peasant base. In turn, the Makhnovists fought against the implementation of the Red Terror and the policy of war communism.

Mikhail Vasilyevich Frunze was a Soviet revolutionary, politician, army officer and military theorist.

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.
