Organization of Ukrainian Nationalists

political organization, Ukraine
Also known as: OUN, Ukrainian Military Organization

Quick Summary

The Organization of Ukrainian Nationalists (OUN) was a political organization founded in 1929. It emerged from the clandestine Ukrainian Military Organization and was influenced by nationalist theories emphasizing the nation's primacy. The OUN engaged in acts of sabotage and assassinations of Polish officials, gaining a following among students and youth, particularly in Galicia.1

During World War II, western Ukrainian territories were occupied by both Soviet and Nazi forces. The OUN itself experienced a significant split in 1940 into two factions: OUN-M, led by Andry Melnyk, and OUN-B, led by Stepan Bandera. These factions differed in their ideology, strategy, and tactics. While the Nazis permitted a limited linguistic and cultural revival under their oversight, political activities were generally banned, with the exception of the OUN.23
