Berenguer Ramon II "the Fratricide" (1053/54 – 1097/99) was count of Barcelona from 1076 to 1097. He was the son of Ramon Berenguer I and Almodis of La Marche, and initially ruled jointly with his twin brother Ramon Berenguer II.
Life
Born in 1053 or 1054, Berenguer Ramon succeeded his father Ramon Berenguer I "the Old" in 1076 to co-rule with his twin brother Ramon Berenguer II. The twins failed to cooperate, leading Pope Gregory VII to appeal for their reconciliation in 1079. The Catalonian possessions were divided between them, against the will of their late father, and it was agreed that the brothers would alternate their residence at the palace in Barcelona every six months.
By 1090, al-Hajib and Berenguer had made several attempts to conquer Valencia which was ruled by Yahya al-Qadir as a vassalage of Alfonso VI of León and Castile. After the compromise in 1086, Berenguer Ramon and al-Hajib had ravaged the surrounding countryside and unsuccessfully besieged the city in 1088 and 1089, Three years later, Berenguer Ramon launched an unsuccessful campaign against Tortosa to secure the territories surrounding the newly settled Tarragona and expand the county of Barcelona. 400 ships employed from Genoa and Pisa contributed to the siege. he joined his half-brother Raymond of Saint-Gilles in the First Crusade as a penance. It is possible that he perished on the walls of Jerusalem in 1099.
