To oversee the Kingdom's revenues and expenditure, the French King first relied solely on the "Curia Regis". However, by the mid-12th century, the Crown entrusted its finances to the Knights Templar, who maintained a banking establishment in Paris. The royal Treasury was henceforth organized like a bank and salaries and revenues were transferred between accounts. Royal accounting officers in the field, who sent revenues to the Temple, were audited by the King's Court, which had special clerks assigned to work at the Temple. These financial specialists came to be called the "Curia in Compotis" and sat in special sessions of the King's Court for dealing with financial business. From 1297, accounts were audited twice yearly after Midsummer Day (24 June) and Christmas. In time, what was once a simple Exchequer of Receipts developed into a central auditing agency, branched off, and eventually specialized into a full-time court.
