Peter IV of Gruyères

Peter IV of Gruyères, also called Perrod (c. 1280–1365), was the son of Rodolphe of Gruyères and nephew of Count Peter III, who raised him and his brother John after they were orphaned young. Knighted around 1327, he was made bailiff of the Pays de Vaud in 1329, and in 1342 he succeeded his uncle as count, ruling jointly with his brother John.

In 1352 he joined the confederacy of Bern and Fribourg, and in 1359 he granted Gruyères its charter of liberties. His second wife Catherine de la Tour-Châtillon bore his successor Rodolphe IV.
