UPA

The UPA (Ukrainian Insurgent Army) was a Ukrainian paramilitary and partisan formation established in 1942 in the territory of Nazi-occupied Ukraine as the armed wing of the Organisation of Ukrainian Nationalists (OUN). It operated mainly in western Ukraine and fought successively against the German occupation, the Soviet forces and, after the Second World War, continued armed resistance against Soviet rule into the mid-1950s. The UPA's history remains deeply contested in Ukrainian, Polish, Russian and broader European memory, in part because its anti-Soviet struggle was accompanied by the ethnic cleansing of Polish civilians in Volhynia and Eastern Galicia in 1943–1945, a subject that continues to shape relations between Ukraine and Poland today.
