|Intro||Count of Barcelona|
Aleran was the Count of Barcelona from 848 to 852. He was also Count of Empúries and Roussillon and Margrave of Septimania together with Isembart from 849 or 850 to 852.
He was a Frankish nobleman loyal to Charles the Bald, King of West Francia. At the Assembly of Narbonne in 849, he and Isembart were empowered to consolidate the territory for the Frankish Kingdom and bring the Hispanic Marches held by rebel forces loyal to Pepin II back into control of the kingdom.
Aleran died sometime in 851 or 852 and the King appointed Odalric as Count of Barcelona in 852.
