Rudolf of Geneva

Late in 1236 or early the next year, during a temporary truce, Rudolf ambushed Peter in a mountain pass, while the latter was travelling with a very small retinue, and made him a prisoner.

On 13 May 1237 Peter's elder brother, Amadeus IV of Savoy, acting as arbiter of the dispute between Geneva and Faucigny, ordered William II to pay a war indemnity and hand over certain fortresses.

When his aunt, Margaret, the dowager countess of Savoy, died in 1258, Rudolf took over the lands at Cornillon and the Val des Clefs that formed her dowry.

Early in 1260 Peter recaptured Charousse and, on 19 May, the three disputants met in Geneva to accept the decision of the arbiters Rudolf and Henry had chosen.

The gagerie included the castles of Geneva, Charousse, Ballaison, Les Clées, Rue; the homages of the Count of Gruyére and of the lords of Langin, Oron and Vufflens; and all the jurisdictions Rudolf possessed in the Pays de Vaud, the Chablais and in Faucigny.

[6] Not long afterwards Boniface died and in August 1263 Rudolf was forced to homage anew to his old enemy, Peter, who was now Count of Savoy.
