History of the Jews in PolandThe history of the Jews in Poland dates back at least 1,000 years. For centuries, Poland was home to the largest and most significant Ashkenazi 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.
