History
As early as the 13th century, inhabitants of the northern two-thirds of Doubs spoke Franc-Comtois, a dialect of the langues d'oïl. Residents of the southern third of Doubs spoke a dialect of the Arpitan language. Both languages co-existed with French, the official language of law and commerce, and continued to be spoken frequently in rural areas into the 20th century. They are both still spoken today but not on a daily basis.
Doubs was important as a portal to Switzerland through the pass at Cluse de Pontarlier. Many famous people, including Mirabeau, Toussaint Louverture and Heinrich von Kleist, were imprisoned in the Château de Joux.
