The history of the Jews in Poland dates back at least 1,000 years. For centuries, Poland was home to the largest and most significant Jewish community in the world. Poland was a principal center of Jewish culture, because of the long period of statutory religious tolerance and social autonomy which ended after the Partitions of Poland in the 18th century. During World War II there was a nearly complete genocidal destruction of the Polish Jewish community by Nazi Germany and its collaborators of various nationalities, during the German occupation of Poland between 1939 and 1945, called the Holocaust. Since the fall of communism in Poland, there has been a renewed interest in Jewish culture, featuring an annual Jewish Culture Festival in Kraków, new study programs at Polish secondary schools and universities, and the opening of Warsaw's Museum of the History of Polish Jews.
From the founding of the Kingdom of Poland in 1025 until the early years of the Polish–Lithuanian Commonwealth created in 1569, Poland was the most tolerant country in Europe. Poland became a shelter for Jews persecuted and expelled from various European countries and the home to the world's largest Jewish community of the time. According to some sources, about three-quarters of the world's Jews lived in Poland by the middle of the 16th century. With the weakening of the Commonwealth and growing religious strife (due to the Protestant Reformation and Catholic Counter-Reformation), Poland's traditional tolerance began to wane from the 17th century. After the Partitions of Poland in 1795 and the destruction of Poland as a sovereign state, Polish Jews became subject to the laws of the partitioning powers, including the increasingly antisemitic Russian Empire, as well as Austria-Hungary and Kingdom of Prussia (later a part of the German Empire). When Poland regained independence in the aftermath of World War I, it was still the center of the European Jewish world, with one of the world's largest Jewish communities of over 3 million. Antisemitism was a growing problem throughout Europe in those years, from both the political establishment and the general population. Throughout the interwar period, Poland supported Jewish emigration from Poland and the creation of a Jewish state in Palestine. The Polish state also supported Jewish paramilitary groups such as the Haganah, Betar, and Irgun, providing them with weapons and training.
