The History of Warsaw Pertaining to the Jews
Jews settled in Warsaw during the middle of the 14th century. They were not popular to the gentile population and were expelled from the city in 1483. The official ban lasted until 1768, when the Jewish population in Warsaw increased to 6,750. During World War 1, the population sky-rocketed to 343,000 Jews, almost 41% of the city's population. Before the Holocaust, Warsaw's Jewish population was 393,950 and rivaled only New York City.
