of Jews was regarded as one-fourth that of the whole country. It is improbable, however, that the whole amount was paid at once, as for many years after the imposition of the tallage, arrears were demanded from the recalcitrant Jews. Aaron of Lincoln is believed to have been the wealthiest man in 12th century Britain. It is estimated that his wealth may have exceeded that of the king. The king had probably been led to make this large demand on English Jewry's money by the surprising windfall which came to his treasury at Aaron's death in 1186. All property obtained by usury, whether by Jew or by Christian, fell into the king's hands on the death of the usurer; Aaron of Lincoln's estate included £15,000 worth of debts owed to him. Besides this, Aaron's large fortune passed to King Henry but much of it was lost on the journey to the royal coffers in Normandy. A special branch of the treasury, known as "Aaron's Exchequer", was established in order to deal with this large account. During the earlier years of Henry II's reign 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 many of the abbeys and monasteries of the country. However, by the end of Henry's reign they had incurred the ill-will of the upper classes. Anti-Jewish sentiment, fostered by the Crusades during the latter part of the reign of Henry, spread throughout the nation. Persecution and expulsion The persecution of England's Jews was brutal, and massacres were recorded in London, Northampton and York during the crusades in 1189 and 1190. The massacre at York was mentioned by William of Newburgh that it was carried out less for religious reasons, but instead for greed. In 1269, Henry III made blasphemy by Jews a hanging offence, and when Edward returned from Crusade, he passed the Statute of Jewry in 1275. The number of Jews were around 2,000 in England. To finance his war against Wales in 1276, Edward I of England taxed Jewish moneylenders. When the moneylenders could no longer pay the tax, they were accused of disloyalty. Already restricted to a limited number of occupations, Edward abolished their "privilege" to lend money, restricted their movements and activities and forced Jews to wear
