Here ya go:
Following World War I, the victors created nearly a dozen new nations in Eastern Europe. These nations were supposed to become democracies, but they would need time to do this. In the 1930s, time ran out. Ethnic differences, political corruption, and finally the Great Depression undermined the infant democracies.
During World War II, Eastern Europe was caught between Nazi Germany and the Soviet Union. Several Eastern European countries--Hungary, Romania, and Bulgaria--aligned themselves with the Nazis. Nazi troops overran most of the rest of Eastern Europe in the first years of the war. (Troops of Fascist Italy took over Albania.) Some Eastern Europeans joined resistance groups to fight the Nazis. The strongest forces emerged in Yugoslavia and Albania, led by communists. By the war's end in 1945, the Soviet Union's Red Army occupied all of Eastern Europe (except Yugoslavia and Albania).
