Berenguer Ramon II, Count of Barcelona
Berenguer Ramon II (c. 1053–1097/1099), called the Fratricide, was count of Barcelona from 1076. Son of Ramon Berenguer I, he first ruled jointly with his twin brother Ramon Berenguer II. Pope Gregory VII appealed for reconciliation in 1079, but the twins partitioned Catalonia against their father's will and alternated palaces.
After Ramon Berenguer II was killed hunting in 1082, murder suspicions sparked civil war, weakening Barcelona's authority over Carcassonne and Razès. A settlement in 1086 made Berenguer Ramon regent for his young nephew Ramon Berenguer III. Twice captured by El Cid, he resigned in 1097 for Jerusalem, possibly dying on the First Crusade.
