A son of William I of Cerdanya and Sancha of Barcelona, he inherited Berga from his father in 1094.
In 1111, after the death of Bernard III of Besalú, he opposed the integration of Besalú into the County of Barcelona as it was technically a feudatory of Cerdanya, as were Fenollet and Vallespir. When he himself died seven years later without heirs, Cerdanya passed to Barcelona.
