The Jewish community played an important role in England throughout much of the period. The first Jews arrived in England in the aftermath of the Norman invasion, when William the Conqueror brought over wealthy members of the Rouen community in Normandy to settle in London. The Jewish community expanded out across England and provided essential money-lending and banking services that were otherwise banned by the usury laws. During the 12th century, the Jewish financial community grew richer still, operating under royal protection and providing the king with a source of ready credit. All major towns had Jewish centres, and even the smaller towns saw visits by travelling Jewish merchants. Towards the end of Henry II's reign, however, the king ceased to borrow from the Jewish community and instead turned to extracting money from them through arbitrary taxation and fines. The Jews became vilified and accusations were made that they conducted ritual child murder, encouraging the pogroms carried out against Jewish communities in the reign of Richard I. After an initially peaceful start to John's reign, the king again began to extort money from the Jewish community and, with the breakdown in order in 1215, the Jews were subject to fresh attacks. Henry III restored some protection and Jewish money-lending began to recover. Despite this, the Jewish community became increasingly impoverished and was finally expelled from England in 1290 by Edward I, being replaced by foreign merchants.
