In 1800, with the creation of the "arrondissements" in France, the eight districts were changed into five "arrondissements": Ambert, Clermont-Ferrand, Issoire, Riom and Thiers. On 10 September 1926, the "arrondissement" of Ambert was eliminated but, in 1942 Ambert became again an "arrondissement" of the department.
