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.
Philippines–Poland relations
With Philippine independence from the United States in 1946 and the eventual establishment of the communist People's Republic of Poland in 1952, relations between the two countries were severed owing to political differences. However, following Soviet–American détente, relations between the two countries were normalized with the formal establishment of diplomatic relations on September 22, 1973, which culminated with the visit of former President Diosdado Macapagal to Poland in 1974, the first visit to the country by any member of the Philippine government.
