William of Jülich
William of Jülich was one of the Flemish noblemen that opposed the annexation policies of the French king Philip IV – together with Pieter de Coninck.
He was also archdeacon at the prince-bishopric of Liège. William was the son of William the Elder and grandson of William IV, Count of Jülich, and of Maria, a daughter of Guy of Dampierre, Count of Flanders and Matilda of Bethune. His connection to the Flemish count and his wish to avenge the imprisoning of his uncles Robert III of Bethune and by the French king presumably explains his support for the Flemish resistance. An extra incentive for this support could have been the murder of his uncle Walram, Count of Jülich by the French after the Battle of Bulskamp in 1297. The Flemish resistance led to the unexpected victory over the French during the Battle of the Golden Spurs in 1302. William of Jülich gained another victory against the French in the Battle of Arques.
In 1304 however, the French king returned with an army and defeated the Flemings during the Battle of Mons-en-Pévèle. William died during this battle.
