Amadeus IV of Geneva

Amadeus IV of Geneva (died 4 December 1369) was the second son of Amadeus III and Mathilde d'Auvergne, and one of five brothers who held the county in turn. In 1367 he succeeded his childless elder brother Aymon III, and that year confirmed the franchises of Annecy.

His father and brother had kept close to Savoy; he reversed that policy and backed the bishops of Lausanne and Geneva against his cousin Count Amadeus VI of Savoy, yet on 13 May 1368 did homage to Amadeus for the county. He then joined Amadeus's Italian campaign against Philip II of Piedmont and attended Philip's trial at Rivoli, possibly hoping to speak with the Emperor.

In February 1369 Charles IV revoked the Savoyard count's vicariate and declared Geneva an immediate imperial fief. Amadeus died that December.
