Robert II of Dreux

Robert II of Dreux, called the Young (c. 1154–1218), succeeded his father Robert I as Count of Dreux in 1184. He took the cross with Philip Augustus in 1190 and fought at the siege of Acre and the battle of Arsuf on the Third Crusade. Back in France he campaigned against the English and in Normandy.

He joined the Albigensian Crusade in 1209, serving at the siege of Termes, and commanded the left wing of the army at the victory of Bouvines in 1214. By his wife Yolande of Coucy he left sons Robert III and Peter Mauclerc, later Duke of Brittany.
