By the end of Henry's reign the king ceased to borrow from the Jewish community and instead turned to an aggressive campaign of tallage taxation and fines. Financial and anti-Semite violence grew under Richard I. After the massacre of the York community in which numerous financial records were destroyed, seven towns were nominated to separately store Jewish bonds and money records and this arrangement ultimately evolved into the Exchequer of the Jews. After an initially peaceful start to John's reign, the king again began to extort money from the Jewish community, imprisoning the wealthier members, including Isaac of Norwich, until a huge, new taillage was paid. During the Baron's War of 1215-7, the Jews were subjected to fresh anti-Semitic attacks. Henry III restored some order and Jewish money-lending became sufficiently successful again to allow fresh taxation. The Jewish community became poorer towards the end of the century and was finally expelled from England in 1290 by Edward I, being largely replaced by foreign merchants.
