Rudolf I of Gruyères

Rudolf I of Gruyères (c. 1120 – c. 1196), the only son of William II, succeeded his father as count around 1145–1154 and was also styled count of Ogo in charters. By his wife Agnes of Glâne, who brought him a large inheritance, he had five children.

He patronised the abbeys of Haut-Crêt and Hauterive. In 1195 pressure from the bishop of Lausanne forced him to surrender Bulle and its market. His son Peter I succeeded him.
