Amadeus III of Geneva

Amadeus III of Geneva (1311–1367) succeeded his father William III as count in 1320, under the regency of his grandmother Agnes of Chalon and mother Agnes of Savoy until 1325. He ruled the Genevois but not the city of Geneva. Caught between Savoy and the Dauphin of Viennois, he fought at Varey in 1325 against his uncle Count Edward of Savoy, then in 1329 did homage to Count Aymon of Savoy, ending nearly a century of conflict.

From 1343 he shared the regency of Savoy with Louis II of Vaud for the boy count Amadeus VI. In 1355 he had to admit defeat as Savoy swept its neighbours, leaving his county enclosed by Savoyard lands.

In 1358 Charles IV took him under imperial protection, outside Savoyard jurisdiction. He died in 1367. Five sons succeeded him in turn, the last becoming the Avignon antipope Clement VII.
