Baldwin V, Count of Hainaut

He was the son of Baldwin IV, Count of Hainaut. In the winter of 1182 on 1183, the Count of Namur-Luxembourg was seriously ill and completely blind, whereupon Balduin immediately visited him on the Luxembourg. There he was reconfirmed as heir by his uncle and was able to receive the homage of several vassals from him. The succession was confirmed by Emperor Frederick I Barbarossa on 22 May 1184 at the Diet of Pentecost in Mainz, on which Balduin acted as imperial sword bearer. Flanders was acquired via his marriage to his widowed third cousin once removed Margaret I of Flanders, Countess of Flanders in 1169.[1] Namur was acquired from his mother Alice of Namur. He was described as "The Count Baldwin with eyes of blue." [2]

He was buried at the monastery of Saint Waudru before the altar of Blessed James the apostle.[3]
