County of Barcelona
The many counties (aside from the counties of County of Pallars, County of Urgell and County of Empuries) were to be soon absorbed into the County of Barcelona and one of his counts, prince Ramon Berenguer IV, count of Barcelona would marry princess Petronilla of Aragon of the Kingdom of Aragon in 1150, uniting as equals the County of Barcelona and the Kingdom of Aragon. Thus, their son became the first king of the Crown of Aragon, ruling over both the Catalans and the Aragonese.
