Ramon Berenguer I, Count of Barcelona

Ramon Berenguer I (1023–1076), called the Old (Catalan:el Vell, French:le Vieux), was Count of Barcelona in 1035–1076. He promulgated the earliest versions of a written code of Catalan law, the Usages of Barcelona.

Born in 1024, he succeeded his father, Berenguer Ramon I the Crooked in 1035. It was during his reign that the dominant position of Barcelona among the other Catalan counties became evident.
