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.
Greater Poland uprising (1918–19)
After the Third Partition of Poland in 1795, the Polish nation had ceased to exist as an independent state. From 1795 through the beginning of World War I, several unsuccessful uprisings to regain independence took place. A 1806 uprising was followed by the creation of the Duchy of Warsaw which lasted for eight years before being partitioned again between Prussia and Russia. Under German rule Poles faced systematic discrimination and oppression. The Poles living in the region of Greater Poland were subjected to Germanisation and land confiscations to make way for German colonization.
