In Poland Jews were living for much longer time than in anny other european state.
Erm....help me out here please!
They came originally from the ME, right? How did they get to Poland first then?
The first authentic document relating to a large and well-organized Jewish community in these regions dates from 321 , and refers to Cologne on the Rhine  ; it indicates that the legal status of the Jews there was the same as elsewhere in the Roman empire. They enjoyed some civil liberties, but were restricted regarding the dissemination of their faith, the keeping of Christian slaves, and the holding of office under the government.
The first Jews arrived in the territory of modern Poland in the tenth century. Travelling along the trade routes leading eastwards to Kiev and Bukhara, the Jewish merchants (known as Radhanites) also crossed the areas of Silesia.
