Individual Details
(1180 - 21 Sep 1239)
Simon was the brother of Renaud I, Count of Dammartin, who had abducted the heiress of Boulogne, and forced her to marry him. It is thought that in order to strengthen the alliance with the Dammartins, King Philip Augustus of France allowed Simon to marry Marie, Countess of Ponthieu, who was a niece of the king, in 1208. Renaud and Simon of Dammartin would eventually ally themselves with John, King of England. In 1214 the brothers stood against Philip Augustus in the Battle of Bouvines. The French won the battle, and Renaud was imprisoned, while Simon was exiled.
