Guilhem de Berguedan

The influential viscount of Cardona then sought to turn Alfonso II and his court against the troubadour, but on 3 March 1175 Guillem dishonorably attacked and killed Ramon.

By his father's will of 1183 Guillem stood to inherit the castles of Madrona (known as Castell Berguedà), Casserres, Puig-reig, Espinalbet, and Montmajor the fief held from Huguet de Mataplana.

Through some poems of Bertran de Born, a friend and fellow troubadour, we know that Guillem was an enemy of Alfonso II.

The will permits us to describe Guillem's power in feudal terms: he held five castles with their knights and vassals and corresponding territories, diverse places and manors in upper and lower Berguedà, a fief in Cerdagne, and rights over Caldes and Sentmenat del Vallès.

In 1195 Bertran de Born composed a song repenting of his career of disputes and wars and encouraging Guillem to do the same.
