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.
Provisional People's Government of the Republic of Poland
On 15 October 1918 Daszyński and other Polish deputies to the Austrian parliament adopted a document in which they declared themselves to be Polish citizens, not Austrian. On 28 October the Polish Liquidation Committee was formed, led by Wincenty Witos first in Kraków, then in Lwów. On 6 November, Daszyński and his deputies proclaimed the formation of the Polish People's Republic led by interim government based in Lublin, with Daszyński as Prime Minister. On Sunday, 10 November at 7 a.m., Józef Piłsudski, newly freed from 16 months in a German prison in Magdeburg, returned by train to Warsaw. Piłsudski, together with Colonel Kazimierz Sosnkowski, was greeted at Warsaw's railway station by Regent Zdzisław Lubomirski and by Colonel Adam Koc. Next day, due to his popularity and support from most political parties, the Regency Council appointed Piłsudski as Commander in Chief of the Polish Armed Forces. On 14 November, the Council dissolved itself and transferred all its authority to Piłsudski as Chief of State ("Naczelnik Państwa"). After consultation with Piłsudski, Daszyński's government dissolved itself and a new government formed under Jędrzej Moraczewski. Italy became the first country in Europe to recognise Poland's renewed sovereignty.
