Independence Day of Poland

Its independence was confirmed by the victorious powers through the Treaty of Versailles of June 1919, and most of the territory won in a series of border wars fought from 1918 to 1921. Poland returned to the map of the world on November 11, 1918 after enduring 123 years of Prussian, Austrian and Russian occupation. The date of 11 November is the one on which Marshal Józef Piłsudski assumed control of Poland. Poland's frontiers were settled in 1922 and internationally recognized in 1923.

The holiday was constituted in 1937 and was celebrated only twice before World War II. After the war, the communist authorities of the People's Republic removed Independence Day from the calendar, though reclamation of independence continued to be celebrated informally on 11 November. As Poland emerged from communism in 1989, the original holiday — on its original 11 November date—was restored.
