The Fourth Regional Congress of Peasants, Workers and Insurgents is held by the Makhnovshchina at Oleksandrivsk.

The Regional Congresses of Peasants, Workers and Insurgents represented the "highest form of democratic authority" within the political system of the Makhnovshchina. They brought together delegates from the region's peasantry, industrial workers and insurgent soldiers, which would discuss the issues at hand and take their decisions back with them to local popular assemblies.

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.

Zaporizhzhia, formerly known as Aleksandrovsk or Oleksandrivsk until 1921, is a city in southeast Ukraine, situated on the banks of the Dnieper River. It is the administrative centre of Zaporizhzhia Oblast. Zaporizhzhia has a population of 710,052.
