Treaty of Lambeth (1212)

The Treaty of Lambeth was signed on 4 May 1212 by King John of England and several French counts, including Renaud I of Dammartin and Boulogne and Ferdinand of Flanders.

By 1212 John had lost his Angevin possessions in France. Renaud lands had also been seized by King Philip II of France. Renaud brought other continental nobles, including Ferdinand, into a coalition against Philip. In return he was given several fiefs in England and an annuity. In the treaty agreed on 4 May 1212, each prince promised not to make a separate peace with France.
