Walter II of Avesnes
Walter II of Avesnes (b. 1170 – d.1244) was lord of Avesnes, Leuze, of Condé and Guise, and through his marriage to Margaret of Blois, he became Count of Blois and of Chartres. He was the son of James of Avesnes, and Adèle, lady of Guise.
Walter fought alongside Ferdinand, Count of Flanders at the Battle of Bouvines in 1214, then left to fight in the Holy Land. Taken prisoner, he was ransomed by the Knights Templar and helped construct the Pilgrim Castle, in 1218, donating 1,000 saracen bezants towards its construction.
