Biography

Simon was son of Alberic III of Dammartin (Aubry de Dammartin) and his wife Mathildis of Clermont, heiress to the county of Clermont and daughter of Renaud II, Count of Clermont.^[1] His brother, Renaud I, Count of Dammartin, who had abducted the heiress of Boulogne, and forced her to marry him. In 1206, King Philip Augustus gave him the castle of St. John.^[2] In order to strengthen the alliance with the Dammartins, King Philip Augustus of France allowed Simon to marry Marie, Countess of Ponthieu, daughter of William IV, Count of Ponthieu, in 1208.^[3][4] 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.^[5] The French won the battle, and Renaud was imprisoned, while Simon was exiled.^[3]

Simon's father-in-law, William IV, Count of Ponthieu had remained loyal to Philip Augustus.^[3] When William died in 1221, Philip Augustus denied Simon's wife's inheritance and gave Ponthieu in custody to his cousin Robert III, Count of Dreux.^[3] Following Philip Augustus's death in 1225, Marie managed to broker a deal with his heir Louis VIII.^[3] Simon could not enter this fief or any other without royal permission, as Ponthieu was held by the king.^[3] Simon accepted the terms in 1231 and added that he would not negotiate his daughters' marriages without the king's approval.^[3]
