at once, as for many years after the imposition of the tallage arrears were demanded from the Jews. The king had probably been led to make this large demand upon English Jewry by the surprising windfall which came to his treasury at the death of Aaron of Lincoln. In this period, Aaron of Lincoln is believed to have been, probably, the wealthiest man in 12th-century Britain, in liquid assets. All property obtained by usury, whether Jewish or Christian, fell into the king's hands on Aaron's death; his estate included £15,000 of debts owed by some 430 debtors scattered around the English counties. In order to track down and collect these debts a special section of the Royal Exchequer was constituted, which was known as the "Aaron's Exchequer". The cash treasure of the Aaron's estate, that came into the king's hands, however, was lost on a shipwreck during a transport to Normandy. In this era, Jews lived on good terms with their non-Jewish neighbours, including the clergy; they entered churches freely, and took refuge in the abbeys in times of commotion. Some Jews lived in opulent houses, and helped to build a large number of abbeys and monasteries. However, by the end of Henry's reign they had incurred the ill will of the upper classes, and anti-Jewish sentiment spread further throughout the nation, fostered by the crusades. Massacres at London and York (1189–1190) Richard I had taken the cross before his coronation (3 September 1189). A number of the principal Jews of England presented themselves to do homage at Westminster; but there was a long-standing custom against Jews (and women) being admitted to the coronation ceremony, and they were expelled during the banquet which followed the coronation, whereupon they were attacked by a crowd of bystanders. The rumour spread from Westminster to London that the king had ordered a massacre of the Jews; and a mob in the Old Jewry, after vainly attacking the strong stone houses of the Jews throughout the day, set them on fire at night, killing those within who attempted to escape. The king was enraged at this insult to his royal dignity, but was unable to punish more than a few of the offenders, owing to their large numbers and to the considerable social standing of several of them. After his departure on the crusade, riots with loss of life occurred at Lynn, where the Jews
