Ukrainian War of Independence: The Ukrainian Soviet Socialist Republic agree to a truce with the Makhnovshchina.

The Ukrainian War of Independence, also referred to as the Ukrainian–Soviet War in Ukraine, lasted from March 1917 to November 1921 and was part of the wider Russian Civil War. It saw the establishment and development of an independent Ukrainian republic, most of which was absorbed into the Ukrainian Soviet Socialist Republic between 1919 and 1920. The Ukrainian Soviet Socialist Republic was one of the constituent republics of the Soviet Union between 1922 and 1991.

The Ukrainian Soviet Socialist Republic, abbreviated as the Ukrainian SSR, UkrSSR, and also known as Soviet Ukraine or just Ukraine, was one of the constituent republics of the Soviet Union from 1922 until 1991. Under the Soviet one-party model, the Ukrainian SSR was governed by the Communist Party of the Soviet Union through its republican branch, the Communist Party of Ukraine.

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 government of Ukraine.

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.
