Otto II of Montferrat

Otto II (c. 1015–1084) was the son of Marquis William III of Montferrat and Waza. He succeeded his father as marquis in 1042 and at first ruled the march jointly with his younger brother Henry, until Henry died in 1045.

He married Constance of Savoy, who bore him three sons. His long rule left little other record. Otto died in 1084 and was followed by his son William IV.
