Facts and Events
Henry V the Blond (1216 – 24 December 1281), called the Great, was the count of Luxembourg, Laroche and Arlon from 1247 to his death and the count of Namur between 1256 and 1264 as Henry III. He was the son and successor of Waleran III of Limburg and Ermesinda of Luxembourg.
In 1240 Henry married Margaret of Bar, daughter of Henry II of Bar and Philippa of Dreux who was the great-granddaughter of King Louis VI of France. Henry's marriage to Margaret brought him Ligny-en-Barrois as her dowry, though, by a clause in the marriage contract, it remained under the feudal suzerainty of the county of Bar. In contempt of this, Henry paid homage in 1256 to Theobald II of Navarre, in his capacity as Count of Champagne. Henry's brother-in-law, Theobald II of Bar, took advantage of the conflict then raging between Frederick III of Lorraine and the bishops of Metz. Henry V was a partisan of the duke and so Theobald took the side of the bishop. Henry was captured in battle at Prény on 14 September 1266. On 8 September 1268, King Louis IX arbitrated between the two counts and Henry was freed and repossessed of Ligny, but under the suzerainty of the Barrois.
In 1256, Henry seized Namur while the reigning margrave, Baldwin II, was also reigning emperor in Constantinople. Baldwin relinquished his rights to Namur to Guy of Dampierre, Count of Flanders, who retook the margraviate from Henry. The two parties made peace and Guy married Henry's daughter.
From Margaret he had the following issue:
He also had at least three bastard sons, including:
