Philip III of Namur
Philip III of Namur (1319–1337), a son of John I, inherited the marquisate in 1336 after his brother Guy II was killed in a tournament in Flanders. He was then in Sweden with his sister Blanche, queen of Sweden and Norway.
Rather than return home, he travelled toward the Holy Land via Cyprus with his brother-in-law. At Famagusta the townsmen, enraged by his party's conduct, killed him and his companions in 1337. His brother William I succeeded him.
