 The Grand Council represented the citizens of Geneva and decided on political matters and also elected the bishops of Geneva after that position was renounced by the Savoy dynasty in 1490.This same council gradually became estranged from the Duke of Savoy.A new cause of friction between the Grand Council and the Duke of Savoy evolved in 1513, when Charles III decided to appoint his cousin John of Savoy as bishop and even secured Papal endorsement.
