Count William of Geneva II

  General Notes:

the Count of Geneva, originally a usurper, from 1225 until his death. He fought a long series of wars with the House of Savoy and lost control of all of his county outside of the traditional Genevois and saw his influence over the city of Geneva proper and the Bishop of Geneva severely reduced.
When Humbert died in 1225, William seized the county and expelled Humbert's sons, his nephews, Peter and Ebal, who eventually found protection under Peter le Petit Charlemagne, who had brought them with him to England by 1244. That year Peter, the elder, married a rich English heiress, Mathilda de Lacy.[1] Peter le Petit Charlemagne was in fact William's nephew, a son of his sister Margaret.
