William II (1307 – 26 September 1345) was Count of Hainaut from 1337 until his death. He was also Count of Holland and Count of Zeeland. He succeeded his father, William I, and married Joanna of Brabant in 1334, but had no issue.[1]

Military career and death[edit]

Holland, 1/4 groat, struck in Geertruidenberg by William IV as Count of Holland.

William fought in France as an ally of the English (he was the brother-in-law of Edward III). He went on crusade against the Saracens and the Lithuanians. He besieged Utrecht, because his one-time favourite bishop John van Arkel of Utrecht had turned against him. He died at Warns, near Stavoren, during one of the battles of Warns against the Frisians in 1345.

After his death[edit]

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