From Wikipedia, the free encyclopedia.

William III of Avesnes (1286 – June 7, 1337) was count William I of Hainaut, count William III of Holland and count William II of Zeeland from 1304 to his death, succeeding his father, John II.

Before becoming count, he was defeated by Guy of Namur at the battle on the island of Duiveland in 1304. Guy and duke John II of Brabant then conquered most of Zeeland and Holland, but these territories were recovered again when william became the new count in the same year. William continued the war with Flanders until the peace of Paris in 1323, where the count of Flanders denounced all claims on Zeeland.

William had occupied most of the bishopric of Utrecht and tried to conquer Friesland. Many of his daughters married with important rulers of Europe and he was called the father in law of Europe. The king of England and the Holy Roman Emperor were married to his daughters, while he was married to the sister of the king of France. William tried to gain support of surrounding counties and duchies for a anti-French coalition.

Internally, William restored order and founded new institutions, like the treasury and the chancellory. The council of the count got more responsibilities.

He married Jeanne of Valois, sister of king Philip VI of France, in 1305 and had the following children:

William IV of Hainaut (1307-1345)
John (died 1316)
Margaret II, Countess of Hainaut (1311-1356), married Louis IV Wittelsbach, Holy Roman Emperor
