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.
Polish People's Party &quot;Left&quot;
The party was established by Jan Stapiński on 5 April 1914 as a breakaway from the Polish People's Party. In the January 1919 elections to elect the first Sejm of the Second Polish Republic it received 3.5% of the vote, winning 12 seats. However, the 1922 elections saw it reduced to two seats in the Sejm and fail to win a seat in the Senate.
