County of Ribagorza

The County of Ribagorza or Ribagorça (Catalan: Comtat de Ribagorça, Aragonese: Condato de Ribagorza, Latin: Comitatus Ripacurtiae) was originally the independent creation of a local Basque dynasty, later absorbed into the Kingdom of Navarre, and then into the Crown of Aragon. Historically it had a strong connection with the counties of Sobrarbe and Pallars. Its territory consisted of the valleys of the rivers Ésera, Isábena, and Noguera Ribagorzana. The seat of its counts was at Benabarre. Other notable towns include Benasque, Graus and Pont de Suert. Today the western portion of the county roughly corresponds to the Aragonese comarca of Ribagorza, with its administrative centre in Graus; the eastern portion roughly corresponds to the Catalan comarca of Alta Ribagorça.

The first history of the region was written in the early fifteenth century and preserved in a fragmentum historicum ex cartulario Alaonis (historical fragment from a cartulary of Alaon).
