The Starobilsk agreement was a 1920 political and military alliance between the Makhnovshchina, an anarchist mass movement led by Nestor Makhno's Insurgent Army, and the Ukrainian Soviet Socialist Republic, which the Bolsheviks had established as the legitimate government of Ukraine.
The agreement was reached following the resurgence of the White movement in Ukraine, which forced the warring Bolshevik and Makhnovist factions to put aside their differences and work together against their common enemy. Its political clauses extended a number of civil liberties to the previously repressed Ukrainian anarchist movement, while its military clauses subordinated the Insurgent Army to the high command of the Red Army.
The agreement was effective from October to November 1920. Following the Soviet victory over the Whites at the siege of Perekop, the Red Army attacked the Makhnovists, bringing an end to the agreement and igniting a conflict between the two factions that would last until the complete suppression of the Makhnovshchina in August 1921.
