Philip of Dreux

Philip of Dreux (Philippe de Dreux; 1158–1217) was a French nobleman, Bishop of Beauvais, and figure of the Third Crusade. He was an active soldier, an ally in the field of Philip Augustus, the French king and his cousin, making him an opponent in campaigns in France and elsewhere of Richard I of England. He was also in demand as a priest, to make and break marriages. He presided over that of his cousin Conrad of Montferrat at the Siege of Acre, marrying him to Isabella I of Jerusalem, daughter of Amalric I, whose marriage he annulled. He was also a party to the annulment of the marriage between Philip Augustus and Ingeborg of Denmark.
