Despite his success in winning the war, William had far less success in restoring royal power following the peace. In part, this was because he was unable to offer significant patronage, despite the expectations from the loyalist barons that they would be rewarded. William attempted to enforce the traditional rights of the Crown to approve marriages and wardships, but with little success. Nonetheless, he was able to reconstitute the royal bench of judges and reopen the royal exchequer. The government issued the Charter of the Forest, which attempted to reform the royal governance of the forests. The regency and Llywelyn came to agreement on the Treaty of Worcester in 1218, but its generous terms – Llywelyn became effectively Henry's justiciar across Wales – underlined the weakness of the English Crown.
