Poland, largely ruined by hostile invasions, tries to draw new settlers from German lands. In order to attract Jews, the King of Poland, Boleslaw the Pious, offers the Jews rights in the form of a charter. Specific rights are given to Jews, distinguishing them from the general population and offering them some autonomy. The charter was followed by others recognizing and extending those rights, like the famous charter of 1333 offered by Casimir the Wise.
