During the Russian Revolution, anarchists such as Nestor Makhno worked to create and defend—through the Revolutionary Insurrectionary Army of Ukraine—anarcho-communism in the Free Territory of the Ukraine from 1919 before being conquered by the Bolsheviks in 1921. A commander of the peasant Revolutionary Insurrectionary Army of Ukraine, also known as the Anarchist Black Army, Makhno led a guerrilla campaign opposing both the Bolshevik "Reds" and monarchist "Whites". The revolutionary autonomous movement of which he was a part made various tactical military pacts while fighting various forces of reaction and organizing the Free Territory of Ukraine, an anarchist society committed to resisting state authority, whether capitalist or Bolshevik.
