History of Poland
The Polish People's Republic ("Polska Rzeczpospolita Ludowa") was established under the rule of the communist Polish United Workers' Party (PZPR). The name change from the Polish Republic was not officially adopted, however, until the proclamation of the Constitution of the Polish People's Republic in 1952.
History of Poland
The Second Polish Republic, established in 1918, existed as an independent state until 1939, when Nazi Germany and the Soviet Union destroyed it in their invasion of Poland at the beginning of World War II. Millions of Polish citizens perished in the course of the Nazi occupation of Poland between 1939 and 1945 as Germany classified ethnic Poles and other Slavs, Jews and Romani (Gypsies) as subhuman. Nazi authorities targeted the last two groups for extermination in the short term, deferring the extermination and/or enslavement of the Slavs as part of the "Generalplan Ost" ('General Plan for the East') conceived by the Nazi régime. A Polish government-in-exile nonetheless functioned throughout the war and the Poles contributed to the Allied victory through participation in military campaigns on both the eastern and western fronts. The westward advances of the Soviet Red Army in 1944 and 1945 compelled Nazi Germany's forces to retreat from Poland, which led to the establishment of a communist satellite state of the Soviet Union, known from 1952 as the Polish People's Republic.
