After his father's death in 1347, William ruled <a href="/wiki/Bavaria" title="Bavaria">Bavaria</a>, Holland and Hainaut together with his five brothers until 1349. With the first division of the <a href="/wiki/Wittelsbach" class="mw-redirect" title="Wittelsbach">Wittelsbach</a> possessions in 1349 he received Hainaut, Holland and <a href="/wiki/Lower_Bavaria" title="Lower Bavaria">Lower Bavaria</a> together with his brothers <a href="/wiki/Stephen_II,_Duke_of_Bavaria" title="Stephen II, Duke of Bavaria">Stephen II</a> and <a href="/wiki/Albert_of_Holland" class="mw-redirect" title="Albert of Holland">Albert I</a>. After the next division of Bavaria in 1353, he ruled together with his younger brother Albert I in <a href="/wiki/Bavaria-Straubing" title="Bavaria-Straubing">Bavaria-Straubing</a>, Holland and Hainaut. </p><p>William had engaged in a long struggle with his mother Margaret, obtaining <a href="/wiki/Count_of_Holland" title="Count of Holland">Holland</a> and <a href="/wiki/Zeeland" title="Zeeland">Zeeland</a> from her in 1354, and <a href="/wiki/County_of_Hainaut" title="County of Hainaut">Hainaut</a> on her death in 1356. </p><p>In 1350, the nobles of Holland asked Margaret to return to Holland again. She then <a href="/wiki/Hook_and_Cod_wars" title="Hook and Cod wars">battled for the power</a> in Holland and Hainaut for some years with her son William who refused to pay her alimony. The Cod league was formed on 23 May 1350 by a number of supporters of William. On 5 September the same year, the Hook league was formed. Soon afterwards, these factions clashed, and a civil war began. </p><p><a href="/wiki/Edward_III_of_England" title="Edward III of England">Edward III of England</a>, Margaret's brother-in-law through her sister <a href="/wiki/Philippa_of_Hainault" title="Philippa of Hainault">Philippa of Hainault</a>, came to her aid. In May 1351 William lost the naval <a href="/wiki/Battle_of_Veere" title="Battle of Veere">Battle of Veere</a>. A few weeks later, the Hooks and their English allies were defeated by William and the Cods in the <a href="/wiki/Battle_of_Zwartewaal" title="Battle of Zwartewaal">Battle of Zwartewaal</a>, which ruined Margaret's cause. Edward III shortly afterwards changed sides, and the empress saw herself compelled (1354) to come to an understanding with her son, he being recognized as count of Holland and Zeeland, she of Hainaut. Margaret died two years later, leaving William in possession of the entire Holland-Hainaut inheritance (July 1356). William was married to Matilda ("Maud" in the English style) of Lancaster, sister to <a href="/wiki/Blanche_of_Lancaster" title="Blanche of Lancaster">Blanche of Lancaster</a>. </p><p>In 1357, on returning from a trip to England, William began to show signs of <a href="/wiki/Insanity" title="Insanity">insanity</a>,<sup id="cite_ref-:0_2-0" class="reference"><a href="#cite_note-:0-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> going so far as to attack and kill one of his knights (Gerard van Wateringe) for no apparent reason, before he could be restrained. His brother Albert assumed the regency in Holland and Hainaut in 1358. William, initially held in <a href="/wiki/The_Hague" title="The Hague">The Hague</a>, was then confined to Castle Le Quesnoy for the remainder of his life.

He was, truly, young and tall, strong and swarthy and agile, more fleet and dexterous than any man in his land, and he had married the daughter of the worthy and valiant Duke of Lancaster; but he was curiously distant and inscrutable: he wouldn't welcome or acknowledge people in the manner of a great prince, and took no pleasure in the company of ladies or damsels, at feasts or otherwise; nor did he have any close confidants (except just one, called master Thierry); and you could never be quite sure whether you were in favor with him or not. And in the end, not long after he'd arranged the peace between the Count of Flanders and the Duke of Brabant, he lost his wits entirely, and most of the time he had to be bound hand and foot. From that point on, the two lands of Hainault and Holland were governed by the lady his wife, and subsequently, since she never had a child by him, by his younger brother Duke Albert.</p><div
