Between 878 and 988 CE, the area became a hotbed of Frankish-Muslim conflict. However, as the Frankish monarchy and the Caliphate of Córdoba both weakened during the 11th century, the resulting impasse allowed for a process of consolidation throughout the region's many earldoms, resulting in their combination into the County of Barcelona, which became the embryo of today's Catalonia. By 1070, Ramon Berenguer I, Count of Barcelona, had subordinated other Catalan Counts and intransigent nobles as vassals. His action brought peace to a turbulent feudal system and sowed the seeds of Catalan identity.
