Alpes-de-Haute-Provence
On 12 August 1793, the department of Vaucluse was created from parts of the departments of Bouches-du-Rhône, Drôme, and Basses-Alpes. Basses-Alpes lost the canton of Sault of Vaucluse. Seventeen years later, in 1810, the canton of Barcillonnette was transferred over to Hautes-Alpes.
