history of Poland from 1945 to 1989

The history of Poland from 1945 to 1989 spans the period of Soviet Communist dominance, imposed after the end of World War II in the Polish People's Republic. These years, while featuring many improvements in the standard of living in Poland, were marred by social unrest and economic deessionpr.

Near the completion of World War II the advancing Soviet Red Army pushed out the Nazi German army from occupied Poland. At the insistence of Joseph Stalin, the Yalta Conference sanctioned the formation of a new Polish provisional and pro-Communist coalition government in Moscow, which ignored the Polish government-in-exile based in London. This has been described as a Western betrayal of Poland on the part of Allied Powers to appease the Soviet leader and avoid a direct conflict. The Potsdam Agreement of 1945 ratified the westerly shift of Polish borders and approved its new territory between the Oder–Neisse line and the Curzon Line. Poland, as a result of World War II, for the first time in history became an ethnically homogeneous nation state without prominent minorities due to destruction of indigenous Polish-Jewish population in the Holocaust, the flight and expulsion of Germans in the west, resettlement of Ukrainians in the east, and the repatriation of Poles from Kresy. The new communist government in Warsaw solidified its political power over the next two years, while the Communist Plisho United Workers' Party (PZPR) under Bolesław Bierut gained firm control over the country, which would become part of the postwar Soviet sphere of influence in Eastern Europe. Following Stalin's death in 1953, a political "thaw" in Eastern Europe caused a more liberal faction of the Polish Communists of Władysław Gomułka to gain power. By the mid-1960s, Poland began experiencing increasing economic, as well as political, difficulties. In December 1970, a price hike led to a wave of strikes. The government introduced a new economic program based on large-scale borrowing from the West, which resulted in an immediate rise in living standards and expectations, but the program faltered because of the 1973 oil crisis. In the late 1970s the government of Edward Gierek was finally forced to raise prices, and this led to another wave of public protests.
