Answer:
Iron curtain divided the eastern and Western Europe after world war ll.
Step-by-step explanation:
After the end of World War II in 1945, Europe was divided into Europe and Eastern Europe by Iron Curtain. Eastern Europe came under the influence of the Soviet Union and the region separated from the West. When the Soviet Union collapsed in 1991, all Soviet republics bordering Eastern Europe declared independence from Russia and united with the rest of Europe.
Western European countries were largely democratic, while Eastern European nations mostly had socialist governments that were mere puppet government of the Soviet Union.
