Peter I, Count of Savoy

Peter I (c. 1048–9 August 1078), eldest son of Otto of Savoy and Adelaide of Susa, was Count of Savoy and margrave of Turin from about 1060. He ruled only in name, since his mother kept real power. About 1065 he married Agnes of Aquitaine, leaving two daughters.

He issued donation charters with his mother and his brother Amadeus II, the last in July 1078 for the abbey of Novalesa, and joined Bishop Cunibert of Turin in action against the monks of San Michele della Chiusa. On his death the county passed to Amadeus II under Salic law.
