Philip I of Savoy

Philip I (1207–1285), youngest son of Thomas I, was a churchman: Bishop of Valence from 1241 and Archbishop of Lyon from 1245, and in 1244 he escorted Pope Innocent IV to Lyon. When the Savoyard succession fell to him, he resigned his sees, married Adelaide of Burgundy in 1267, and succeeded his brother Peter II as count in 1268.

He acquired Bresse in 1272, but in 1282 faced a coalition led by King Rudolph I and Charles of Anjou. He died childless in Roussillon on 16 August 1285, and his nephew Amadeus V succeeded him.
