Basses-Pyrénées is one of the original 83 departments of France created during the French Revolution, on March 4, 1790. It was created from parts of the former provinces of Guyenne, Béarn, and Gascony and included the three traditional provinces of the northern Basque Country: Labourd, Soule and Basse-Navarre. It also included two tiny exclaves of Bigorre which were located within Béarn.
The previous history of the region, under the Ancien Régime, can be found at those individual articles.
On October 10, 1969, Basses-Pyrénées was renamed Pyrénées-Atlantiques.
