Nestor Ivanovych Makhno, also known as Batko Makhno, was a Ukrainian anarchist revolutionary and the commander of the Revolutionary Insurgent Army of Ukraine during the Ukrainian War of Independence. He established the Makhnovshchina, a mass movement by the Ukrainian peasantry to establish anarchist communism in the country between 1918 and 1921. Initially centered around Makhno's home province of Katerynoslav and hometown of Huliaipole, it came to exert a strong influence over large areas of southern Ukraine, specifically in what is now the Zaporizhzhia Oblast of Ukraine.

The Revolutionary Insurgent Army of Ukraine, also known as Makhnovtsi, named after their leader Nestor Makhno, was an anarchist army formed largely of Ukrainian peasants and workers during the Russian Civil War of 1917–1922. They protected the operation of "free soviets" and libertarian communes by the Makhnovshchina, an attempt to form a stateless anarcho-communist society from 1918 to 1921 during the Ukrainian War of Independence.
