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.
Territorial evolution of Poland
The non-historical West Ukrainian People's Republic was proclaimed on November 1, 1918, with Lviv as its capital. The Republic claimed sovereignty over Eastern Galicia, including the Carpathians up to the city of Nowy Sącz in the west, as well as Volhynia, Carpathian Ruthenia and Bukovina. Although the majority of the population of the Western-Ukrainian People's Republic were Ukrainians, hereto an unknown nationality, large parts of the claimed territory were considered Polish by the Poles. In Lviv the Ukrainian residents supported the proclamation, the city's significant Jewish minority accepted or remained neutral towards the Ukrainian proclamation, and the Polish majority was shocked to find themselves in a proclaimed Ukrainian state.
