As early as the 13th century, inhabitants of the southern 2/3 of Jura spoke a dialect of Arpitan language. It continued to be spoken in rural areas into the 20th century.
Jura is one of the original 83 departments created during the French Revolution on March 4, 1790. It was created from part of the former province of Free County. The department was created with six districts: Dole, Lons-le-Saunier, Orgelet, Poligny, Saint-Claude and Salins; the capital was Lons-le-Saunier alternating with Dole, Poligny and Salins but from 1794 only Lons-le-Saunier remained as the capital.[4]
In 1800, with the creation of the arrondissements in France, the six districts were changed into four arrondissements: Lons-le-Saunier, Dole, Poligny and Saint-Claude. On 10 September 1926, the arrondissement of Poligny was eliminated.[4]
Many lakes can be found throughout the Jura department. The largest natural lake in the department is the Lac De Chalain. It is 3 km (1.9 mi) long and 1 km (0.6 mi) wide. Lac de Vouglans was formed after the building of a hydro-electric dam; it is one of the largest man-made lakes in France.
The Ainriver starts in the Jura department but it is the main river of the Ain department. The Doubs also flows through a part of the department. Many tributaries of both rivers flow, partially or completely, in the Jura department.

The climate of the Jura varies greatly by elevation. The lower valleys are temperate and pleasant, but the high mountain valleys have bitterly cold winters.
