Origins & Early Life

The Treaty of Lambeth of 1217, also known as the Treaty of Kingston to distinguish it from the Treaty of Lambeth of 1212, was a peace treaty signed by Louis of France in September 1217 ending the campaign known as the First Barons' War to uphold the claim by Louis to the throne of England. When the campaign had begun, baronial enemies of the unpopular English king John had flocked to the French banner, but after John's death in 1216, and his replacement by a regent, William Marshal, on behalf of John's young son and successor, Henry III, many had switched sides.

Career & Major Achievements

Subsequent defeats at Lincoln in May 1217 and at Dover and Sandwich in August 1217 forced Louis to negotiate. Information on the treaties is based on three early documents but none of these is known to have been based on an original manuscript.

Enduring Legacy & Impact

It is known that negotiations were spread over several locations, opening on 6 September 1217 at Staines, because the royal court was nearby at Chertsey or possibly on 5 September on an island of the Thames near Kingston.
