Amadeus of Savoy-Achaea

Amadeus of Savoy-Achaea (c. 1321–1376) was a younger son of Philip I, lord of Piedmont, and Catherine de la Tour du Pin. The cadet branch of Savoy that held Piedmont put its younger sons into the church, and Pope Clement VI, who favoured the house of Savoy, obliged.

Amadeus, already promised prebends, was made Bishop of Maurienne on 2 April 1349 before he had taken even minor orders. Count Amadeus VI of Savoy later tried to exchange his see for Lausanne: both bishops agreed and resigned, but Innocent VI answered too slowly and the exchange failed.

His brother Thomas became Bishop of Turin in November 1348. Amadeus died at Saint-Jean-de-Maurienne on 6 June 1376 and seems to have been buried in its cathedral.
