Amadeus II of Geneva

Amadeus II (died 22 May 1308) was the Count of Geneva, which included the Genevois, but not the city of Geneva, from 1280. He was the second son of Count Rudolf and succeeded his heirless brother Aymon II.

In June 1282 at Versoix, Amadeus and Béatrice “la Grande Dauphine”, the dowager Countess of Albon and regent for her son John I, came to an agreement whereby all the places that Amadeus' father and grandfather, William II, had been forced to cede to Peter “the Little Charlemagne” in 1250 and 1260—the so-called gagerie—would be returned to Geneva. The gagerie was originally to be held by Peter and his heirs until the Count of Geneva paid a war indemnity of 20,000 marks, later reduced to 10,000. Béatrice was Peter's only daughter and heir, and the widow of Guigues VII of Albon. In return for these lands, Amadeus granted to Béatrice suzerainty over certain lordships and agreed to take any allods within the returned gagerie as fiefs of her and her heirs, the Counts of Albon, instead. The treaty also created a mutual defensive alliance and cooperation in an offensive against "those detaining and possessing the properties and men belonging to the above-mentioned gagerie", that is, men of the house of Savoy, Béatrice's relatives. The conference of Versoix was under the presidency of Amadeus' uncl,e the Bishop of Geneva, who promised to help both parties so far as it did not threaten the rights of his diocese. The privilege of arbitrating disputes between Amadeus and Béatrice fell to Humbert I of La Tour-du-Pin, who was Béatrice's son-in-law as the husband of her daughter Anne.
