Otto, Count of Savoy

Otto (c. 1023–1057/1060), also called Oddone, was Count of Savoy from about 1051, a younger son of Humbert the White-Handed and Ancilla of Lenzburg. In 1046 he married Adelaide, heiress of the march of Susa and the county of Turin, and thereafter administered her Italian lands.

Succeeding his brother Amadeus I, he joined the counties of Maurienne and Aosta to Turin and Susa, turning the House of Savoy toward Italy. In the 1050s he briefly minted coins at Aiguebelle until a papal complaint made him stop. His son Peter I succeeded him.
