Arrondissements of the Dordogne department
1790 : creation of the Dordogne department with nine districts: Belvès, Bergerac, Excideuil, Montignac, Montpon, Nontron, Périgueux, Ribérac and Sarlat. Bergerac, Périgueux and Sarlat-la-Canéda were alternatively the capital of the department but later, in the same year, it was decided that only Périgueux would be the capital.
