History of the Jews in Łódź began at the end of the 18th century when the first Jews arrived to the city. The community grew and became one of the largest Jewish communities in Europe. During the Holocaust the Jewish population of the city was concentrated in the northern-district of the city, Baluty, where a Nazi ghetto was established. The community numbers a few hundreds and is headquartered at the Karol Gebhardt House located in 18 Pomorska Street in the city. History The beginnings of Jewish settlement in Łódź date back to the 18th century, the period of the fall of the Polish-Lithuanian Commonwealth. The city did not have the de non tolerandis Judaeis privilege. The first known Jewish inhabitants of the city were Daniel Layzerowicz, a baker and Abram Lewkowicz, a tailor. They both lived in Łódź already in 1785. In 1791 Mosiek aka Mojżesz Pryntz from Lutomiersk settled here. The first wealthy and learned Jews living in Łódź were: Pinkus Zajdler, who came from Przedbórz in 1795, Pinkus Sonenberg, who came in 1797 from Łęczyca, and Lewek Heber, who came to Łódź in 1801 from Lutomiersk. They all played an important role, performing the functions of successive members of the Jewish community. The influx of Jewish people to the town was not large until the Second Partition of Poland in 1793. Out of a total of 190 inhabitants, only 11 were Jews. It was undoubtedly influenced by the character of the city; it was still the so-called a typical agricultural village, not very attractive to newcomers. The fact that Łódź was the property of the bishop until the Second Partition of Poland was also of great importance for the Jewish settlement; only in the period 1796–1798 it became a government city. In the years 1818-1817 the Jews of Lodz constituted about a third of the city's inhabitants and most of them were poor. In 1825, German experts were invited to Łódź to help industrialize the city. The Germans signed a treaty called the "Zagirez Treaty" which included restrictions on the Jews. The Jews were required to live in the southern edges of the city, and move to the Jewish quarter within two years, except for two families who received permission to live in another part of the city. This area covered the southern side of the Old Market Square, Wolborska and Podrzeczna Streets up to the Łódka River.
