William II of Burgundy

William II of Burgundy (c. 1075–1125), called the German, was Count of Burgundy, Mâcon and Vienne. The only son of Reginald II, he was raised by his maternal grandfather Count Conon in the Alemannic lands around Bern, which gave him his nickname.

When his father died on the First Crusade in 1097 he succeeded jointly with his uncle Stephen I. In 1125 he was killed in a plot by his own barons, and his young son William III was assassinated two years later.
