ルッジェーロ1世
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.
