William I of Sicily

William I (1120 or 1121May 7, 1166), called the Bad or the Wicked, was the second king of Sicily, ruling from his father's death in 1154 to his own in 1166. He was the fourth son of Roger II and Elvira of Castile. William's title "the Bad" seems little merited and expresses the bias of the historian Hugo Falcandus and the baronial class against the king and the official class by whom he was guided. Early life William was the son of King Roger II of Sicily, grandson of Count Roger I of Sicily, and great-grandson of Tancred of Hauteville. He grew up with little expectation of ruling. The deaths of his three older brothers Roger, Tancred, and Alfonso between 1138 and 1148 changed matters, though when his father died William was still not well-prepared to take his place.
