September 1217 CE
The barons, mollified by the regency’s reforms, have by now deserted Louis; in September 1217 de Burgh and Marshal persuade him to leave England, concluding a peace treaty with him.
Giving up his claim to the English throne and signing the Treaty of Lambeth, Louis returns to France to take a principal role in the Albigensian Crusade.
