Life

William was born in 1307, the son of William I of Hainaut and Joan of Valois.^[1]

In 1334, he married Joanna, Duchess of Brabant, the daughter and heiress of John III, Duke of Brabant, but had no issue.^[2]

He fought in France as an ally of the English (he was the brother-in-law of King Edward III of England). In 1339, William participated in the Siege of Cambrai (1339).^[3] In 1345, two months before he died, he besieged and took Utrecht [fr; nl], because the bishop, John van Arkel, was trying to regain the bishopric's historical independence from Holland.

William fought against the Saracens,^{[citation needed]} and went on crusade with the Teutonic Order in Prussia.^[4] He was killed near Stavoren, during one of the battles of Warns against the Frisians in 1345.^[5]

William was succeeded by his sister, Margaret of Hainaut, who was married to Louis IV, Holy Roman Emperor. Hainaut, Holland and Zeeland became a part of the imperial crown domains.
