Ukraine

Western Ukraine under Soviet and Nazi rule

The Nazi German invasion of Poland on September 1, 1939, marked the beginning of World War II. By mid-September, in accordance with the secret protocols of the German-Soviet Nonaggression Pact (Molotov-Ribbentrop Pact), western Volhynia and most of Galicia, both previously under Polish rule, were occupied by Soviet troops and soon officially incorporated into the Ukrainian S.S.R. In June 1940 northern Bukovina was occupied and shortly annexed to Soviet Ukraine from Romania (which sided with Germany during the war). The replacement of Polish and Romanian by the Ukrainian language in state administration and education was offset by a suppression of all existing organizations, Sovietization of institutional life, and arrests of political leaders and community activists. By mid-1941 more than one million people had been deported to the east, including large numbers of Poles and Jews.

The ethnically mixed western borderlands, with more than 500,000 Ukrainians, were included in the administrative region of Poland established by the Nazis. A limited linguistic and cultural revival in the heavily Polonized area was permitted under German oversight, but political activities were banned, except for the OUN. The OUN itself was rent by factional strife between the followers of Andry Melnyk, who headed the organization from abroad after the assassination of Konovalets by a Soviet agent in 1938, and the younger supporters of Stepan Bandera with actual experience in the conspiratorial underground. The split became permanent after a congress held in Kraków in February 1940, when the Melnyk and Bandera factions developed into separate organizations (OUN-M and OUN-B, respectively) differing in ideology, strategy, and tactics.
