Bera of Barcelona

Bera (Catalan: Berà) (died 844) was the first count of Barcelona from 801 until his deposition in 820. He was also the count of Razès and Conflent from 790, and the count of Girona and Besalú from 812 (or 813 or 817) until his deposition. In 811, he was witness to the last will and testament of Charlemagne.

Bera's origins are mostly unknown, although it seems certain that he was a Visigoth. He may have been one of the sons of William of Gellone, Count of Toulouse and cousin of Charlemagne, although this is not supported by William's detailed will from 804. In 790, Bera was given the governship of the counties of Razès and Conflent, possibly by William. The Counties of Roussillon (with the pagus of Vallespir) and Empúries were given to William's son Gaucelm, whose mother was Gunegunde (Cunegonde), one of William’s two wives.

In 796, Sa'dun al Ruayni, the Wali of Barcelona, attempted to break his allegiance to Al-Hakam I, emir of Córdoba. In April 797, he travelled to Aachen and offered to switch the city’s alligence to Charlemagne in exchange for help against Córdoba. Charlemagne summoned an assembly in Toulouse in the spring of 800 which agreed to send his son Louis the Pious to Barcelona.
