The Territoire de Belfort (French pronunciation: [tɛʁitwaʁ bɛlfɔʁ] ; lit. "Territory of Belfort") is a department in the northeastern French region of Bourgogne-Franche-Comté. In 2020 it had a population of 140,120.[3] The department, which encompasses a relatively small surface area of 609.4 km2 (235.3 sq mi), is located just southwest of the European Collectivity of Alsace. It also shares a border with the Swiss canton of Jura to the southeast. Its prefecture is Belfort.


The administrative district Territoire de Belfort was created under the terms of the 1871 Treaty of Frankfurt. The German Empire annexed almost all of Alsace, but the French were able to negotiate retention of the Territoire de Belfort which thereby was separated from the rest of Alsace (where it had been part of the department of Haut-Rhin). There were three principal reasons for this exceptional treatment:

After retaining its unique status as a territoire for just over half a century, Belfort was officially recognized as France's 90th department in 1922. France had recovered Alsace three years earlier, but the decision was taken not to reintegrate Belfort into its former department. There was talk of giving it a new departmental name, with suggestions that included "Savoureuse" (after the main river of the new department) or "Mont-Terrible" (the name of a former Napoleonic department embracing parts of Switzerland), but there was no consensus for a name change and the department continues to be known as the Territoire de Belfort.

When the regions of France were created, Belfort was not included in the region of Alsace, but the adjacent region of Franche-Comté, since January 2016 Bourgogne-Franche-Comté.


Geographers might contend that Belfort lies on the ridge that divides two regions of France, but before 1870 it was politically part of Alsace. However, in terms of the political regions established in 1982, the Territoire de Belfort has found itself in the Franche-Comté rather than Alsace.

The department has an area of only 609 km2 (235 sq. miles), being the fifth smallest of France (after Paris and its suburbs Hauts-de-Seine, Seine-Saint-Denis, and Val-de-Marne). It is slightly smaller than Saint Lucia or Jakarta, Indonesia.

The median net income per household for the department in 2017 was €21,310. The averaged figure for the Territoire de Belfort masked relatively large disparities such as, in particular, that between Belfort itself at €17,920 and Bermont at €26,600.[5]

Population and demographics

In 2019 the department recorded a population of 141,318. Of these, slightly more than 46,000 live in the commune of Belfort itself, which accounts more than 32% of the departmental population.
