Operation Faustschlag in the context of "Romanian military intervention in Bessarabia"

Nestor Ivanovych Makhno (Ukrainian: Нестор Іванович Махно, pronounced [ˈnɛstor iˈwɑnowɪtʃ mɐxˈnɔ]; 7 November 1888 – 25 July 1934), also known as Bat'ko Makhno (Ukrainian: Бáтько Махно́ [ˈbɑtʲko mɐxˈnɔ], lit. 'Father 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 (loosely translated as "Makhno movement"), 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.

Raised by a peasant family and coming of age amid the fervor around the 1905 Revolution, Makhno participated in a local anarchist group and spent seven years imprisoned for his involvement. With his release during the 1917 Revolution, Makhno became a local revolutionary leader in his hometown and oversaw the expropriation and redistribution of large estates to the peasantry. In the Ukrainian Civil War, Makhno sided with the Soviet Russian Bolsheviks against the Ukrainian nationalists and White movement, but his alliances with the Bolsheviks did not last. He rallied Bolshevik support to lead an insurgency, defeating the Central Powers' occupation forces at the Battle of Dibrivka and establishing the Makhnovshchina. Makhno's troops briefly integrated with the Bolshevik Red Army in the 1919 Soviet invasion of Ukraine, but split over differences on the movement's autonomy. Makhno rebuilt his army from the remains of Nykyfor Hryhoriv's forces in western Ukraine, routed the White Army at the Battle of Perehonivka, and captured most of southern and eastern Ukraine, where they again attempted to establish anarchist communism.

The Makhnovshchina (Ukrainian: Махновщина, romanized: Makhnovshchyna, IPA: [mɐxˈnɔu̯ʃtʃɪnɐ]) was a mass movement to establish anarchist communism 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. It controlled territory in southern and eastern Ukraine.

The Makhnovist movement first gained ground in the wake of the February Revolution, when it established a number of agricultural communes in Makhno's home town of Huliaipole. After siding with the Bolsheviks during the Ukrainian–Soviet War, the Makhnovists were driven underground by the Austro-German invasion and waged guerrilla warfare against the Central Powers throughout 1918. After the insurgent victory at the Battle of Dibrivka, the Makhnovshchina came to control much of Katerynoslav province and set about constructing anarchist-communist institutions. A Regional Congress of Peasants, Workers and Insurgents was convened to organise the region politically and economically, with a Military Revolutionary Council being established as the movement's de facto executive organ.

The Treaty of Brest-Litovsk was a separate peace treaty signed on 3 March 1918 between Soviet Russia and the Central Powers (Germany, Austria-Hungary, the Ottoman Empire, and Bulgaria), by which Russia withdrew from World War I. The treaty, which followed months of negotiations after the armistice on the Eastern Front in December 1917, was signed at Brest-Litovsk (now Brest, Belarus).

The Soviet delegation was initially headed by Adolph Joffe, and key figures from the Central Powers included Max Hoffmann and Richard von Kühlmann of Germany, Ottokar Czernin of Austria-Hungary, and Talaat Pasha of the Ottoman Empire. In January 1918, the Central Powers demanded secession of all occupied territories of the former Russian Empire. The Soviets sent a new peace delegation led by Leon Trotsky, which aimed to stall the negotiations while awaiting revolutions in Central Europe. A renewed Central Powers offensive launched on February 18 captured large territories in the Baltic region, Belarus, and Ukraine and forced the Soviet side to sue for peace.
