Otto, Count of Savoy

Otto (or Othon in French, Oddone in Italian) (1010/1020 – c. 1057) was a Count of Savoy from 1051 (or 1056) until his death.

He substantially enlarged his lands through his marriage. After this acquisition the House of Savoy concentrated their expansion efforts towards Italy instead of outside the Alps as they had done before. Savoy's lands occupied much of modern Savoy and Piedmont, although several other small states could be found between them.


He was son of Humbert, the first Count of Savoy, and his wife Ancilla of Lenzburg, and ascended the throne after the death of his elder brother, Amadeus I of Savoy.

In 1046 he married Adelaide, heiress of Turin and Susa. They had five children:
