William I, Duke of Bavaria
From Wikipedia, the free encyclopedia
William I, Duke of Bavaria-Straubing (Frankfurt am Main, May 12, 1330 – April 15, 1389, Le Quesnoy) , was the second son of the emperor Louis IV the Bavarian from his second wife Margaret of Holland and Hainaut. He was also known as William V, Count of Holland, as William III, Count of Hainaut and as William IV, Count of Zeeland.
In 1345 William's father was conferring Hainaut, Holland, Zeeland and Friesland upon his wife Margaret, and shortly later also upon their son William. After his father's death in 1347 William ruled Bavaria, Holland and Hainaut together with his five brothers until 1349. With the first division of the Wittelsbach possessions in 1349 he received Hainaut, Holland and Lower Bavaria together with his brothers Stephen II and Albert I. After the next division of Bavaria in 1353 he ruled together with his younger brother Albert I in Bavaria-Straubing, Holland and Hainaut.
William had engaged in a long struggle with his mother Margaret, obtaining Holland and Zeeland from her in [1354]], and Hainaut on her death in 1356.
In 1350, the nobles of Holland asked Margaret to return to Holland again. She then battled for the power in Holland and Hainaut for some years with her son William who refussed to pay her alimony. The Cod league was formed in May 23, 1350 by a number of supporters of William. On September 5 of the same year, the Hook league was formed. Soon afterward, these factions clashed, and a civil war began.
Edward III of England, Margaret's brother in law through her sister Philippa of Hainault, came to her aid, winning a naval engagement off Veere in 1351; a few weeks later the Hooks and their English allies were defeated by William and the Cods at Vlaardingen, an overthrow 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 Blanche of Lancaster.
In 1357, he began to show signs of insanity, and his brother Albert assumed the regency in Holland and Hainaut in 1358. William was confined for the remainder of his life.

He was succeeded by his brother Albert in 1388.
