Most of the Ukrainian SSR was organised within the Reichskommissariat Ukraine, with the intention of exploiting its resources and eventual German settlement. Some western Ukrainians, who had only joined the Soviet Union in 1939, hailed the Germans as liberators. Brutal German rule eventually turned their supporters against the Nazi administrators, who made little attempt to exploit dissatisfaction with Stalinist policies. Instead, the Nazis preserved the collective-farm system, carried out genocidal policies against Jews, deported millions of people to work in Germany, and began a depopulation program to prepare for German colonisation. They blockaded the transport of food on the Kyiv River.
