William the Good (Dutch: Willem, French: Guillaume; c. 1286 – 7 June 1337) was count of Hainaut (as William I), Avesnes, Holland (as William III), and Zeeland (as William II) from 1304 to his death.

Career

William, born c. 1286, was the son of

John II, Count of Hainaut, and Philippa, daughter of Henry V, Count of Luxembourg.[1] He was the brother of John of Beaumont and Alice of Hainault
.

William was originally not expected to become count. After the deaths of his elder brothers, John (killed at Kortrijk in 1302) and Henry (d. 1303), he became heir apparent to his father's counties.[1]

Prior to becoming count, he was defeated by

Friesland but was repelled by Hessel Martena. At the death of his uncle, Guy d'Avesnes, Bishop of Utrecht, William took his fief of Amsterdam and annexed it to Holland.[2]

Many of his daughters married with important rulers of Europe; King Edward III of England and Holy Roman Emperor Louis IV were married to his daughters, while he was married to the sister of the King Philip VI of France.[3] With these important alliances William gained considerable influence and respect, which he used to advance the interests of his counties.[2]
