Aaron of Lincoln

Aaron of Lincoln (born at Lincoln, England, about 1125, died 1186) was an English Jewish financier . He is believed to have been the wealthiest man in Norman England; it is estimated that his wealth exceeded that of the King. He is first mentioned in the English pipe-roll of 1166 as creditor of King Henry II for sums amounting to £616 12s 8d in nine of the English counties. He conducted his business through agents, and sometimes in conjunction with Isaac, fil Joce; by these methods building up what was practically a great banking association that spread throughout England.

He made a speciality of money lending for the purpose of building abbeys and monasteries. Among those built were the Abbey of St. Albans, Lincoln Minster, Peterborough Cathedral, and no fewer than nine Cistercian abbeys. They were all founded between 1140 and 1152, and at Aaron's death remained indebted to him in no less a sum than 6,400 marks. Some of these debts may, however, have been incurred by the abbeys in order to acquire lands pledged to Aaron. Thus the abbot of Meaux took over from Aaron lands pledged to the latter in the sum of 1,800 marks; Aaron at the same time promising to commute the debt for a new one of only 1,260 marks, which was paid off by the abbey. After Aaron's death the original deed for 1,800 marks was brought to light, and the king's treasury demanded from the abbey the missing 540 marks. This incident indicates how, on the one hand, Aaron's activity enabled the abbeys to get possession of the lands belonging to the smaller barons, and, on the other, how his death brought the abbeys into the king's power.

Aaron not only advanced money on land, but also on corn, armour, and houses, and in this way acquired an interest in properties scattered through the eastern and southern counties of England. By the time he died, in 1186, he was perhaps the richest man in Britain, his wealth possibly exceeding the king's. Upon his death Henry II seized his property as the escheat of a Jewish usurer, and the English crown thus became universal heir to his estate. The actual cash treasure accumulated by Aaron was sent over to France to assist Henry in his war with Philip Augustus, but the vessel containing it went down on the voyage between Shoreham and Dieppe. However, the indebtedness of the smaller barons and knights remained, and fell into the hands of the king to the amount of £15,000, owed by some 430 persons distributed over the English counties.

So large was the amount that a separate division of the exchequer was constituted, entitled "Aaron's Exchequer" (Madox, History of the Exchequer, folio ed., p. 745), and was continued till at least 1201, that is, fifteen years later, for on the pipe-roll of that year most of the debts to Aaron (about £7,500) are recorded as still outstanding to the king, showing that only half the debts had been paid over by that time, though, on the death of Aaron, the payment of interest ceased automatically, since the king, as a Christian, could not accept usury.

In 1190, Richard de Malbis (Richard Malebisse), a debtor of Aaron of Lincoln, led an attack on the family of Aaron's late agent in York that resulted in the death of the entire Jewish community, some 150 men, women, and children, at York Castle.

A house sometimes associated with Aaron of Lincoln still stands, also known as Norman House, and is probably the oldest private stone dwelling in England the date of which can be fixed with precision (before 1186). While the house is associated with a Jewish banker, and historically known as "Aaron the Jew's house", it is not known whether the house actually had any association with Aaron of Lincoln. Originally the house had no windows on the ground floor—an omission probably intended to increase the facilities for protection or defence.

What makes Aaron significant is that his career illustrates the manner in which the medieval Jewish communities could be organised into a banking association reaching throughout an entire country. Still, the ultimate fate of the wealth thus acquired shows that, in the last resort, the state obtained the chief benefit.
