Otto I, Count of Savoy

Otto (or Othon in French, Oddone in Italian) (1010 or 1020 – c. 1057) was Count of Savoy from 1051 (or 1056) until his death. He was son of Humbert I, the first Count of Savoy, and his wife Ancilla, and ascended the throne after the death of his elder brother, Amadeus I of Savoy.

Otto substantially enlarged his lands through his marriage with Adelaide of Susa, margravine of Turin and Susa, a title she had inherited from her father Ulric Manfred II. 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.
