1186 AARON OF LINCOLN (born c.1123) (England)
The richest man in England died. King Henry II immediately seized his estate when he died worth over 15,000 pounds. Aaron had such vast sums owed to him that the royal officials set up a special branch of the exchequer called the "exchequer of Aaron" (Scaccarium Aaronis) to deal with it. After 16 years they only succeeded in recovering about half of the debts owed him. Some of his debtors included the King of Scotland, the Archbishop of Canterbury, the Count of Brittany and many other nobles. It was the forerunner of the system of debt registries for Jewish loans (the archae), in selected cities established by Richard's administration in 1194; these registries enabled the king's men to keep their finger on the pulse of Jewish lending (and allowed easier raising of money from the Jews).
