History

Belfort's strategic location, in a natural gap between the Vosges and the Jura, on a route linking the Rhine and the Rhône, has attracted human settlement and made it a target for armies.

The site of Belfort was inhabited in Gallo-Roman times and was subsequently recorded in the 13th century as a possession of the counts of Montbéliard, who granted it a charter in 1307.

Previously an Austrian possession, Belfort was transferred to France by the Treaty of Westphalia (1648), that ended the Thirty Years' War. The town's fortifications were extended and developed by the military architect Vauban for Louis XIV.

Until 1871, Belfort was part of the département of Haut-Rhin, in Alsace. The Siege of Belfort, between 3 November 1870 and 18 February 1871, was successfully resisted until the garrison was ordered to surrender 21 days after the armistice between France and Prussia. Because this part of Alsace was French speaking, while the rest of Alsace was German speaking, the area around Belfort was not annexed by the Prussians. It formed, as it still does, the Territoire de Belfort. The siege is commemorated by a huge statue, the Lion of Belfort, by Frédéric Bartholdi.

Alsatians who sought a new French home in Belfort made a significant contribution to its industry (see Société Alsacienne de Constructions Mécaniques).

The town was bombarded by the German army during World War I and occupied by it during World War II. In November 1944 the retreating German army held the French First Army before the town until French Commandos made a successful night attack on the Salbert Fort. Belfort was liberated on 22 November 1944.
