Count of Ampurias and Roussillon, born to 790 and died in 844. The historian D'abadal considered an intruder within the Government of Sunyer I. During the 9th century the Catalan counties formed part of the Spanish brand and their counts were appointed by the Carolingian Kings.
Its origin is unknown, although some theories are running that it might have been the brother of Sunyer I of Ampurias and Roussillon. In 843, during the Barcelona Office of Sunyer I, Alaric received the Government of the County of Ampurias and Roussillon, which he/she retained until his death in 844; After this the counties returned to Sunyer I.
