>>510191249The General Charter of Jewish rights known as the Statute of Kalisz, and the Kalisz Privilege, granted Jews in the Middle Ages some protection against discrimination in Poland compared to other places in Europe. These rights included exclusive jurisdiction over Jewish matters to Jewish courts, and established rules of evidence for criminal matters involving Christians and Jews.[1]
The statute was issued by the Duke of Greater Poland Bolesลaw the Pious on September 8, 1264 in Kalisz. After the unification of Poland, the statute was then ratified by some subsequent Polish Kings: Casimir the Great in 1334, Casimir IV in 1453, and Sigismund I in 1539.[2] This was in contrast to other rulers in Western and Southern Europe at the time who forced Jews to emigrate: England in 1290, France in 1306, Spain in 1492.
Jewish subjects in Poland were freemen allowed to trade, rather than serfs, and so further enjoyed the country's religious toleration codified by the Warsaw Confederation of 1573.
