Its departmental code is 90, and its prefecture is Belfort. There is a single arrondissement, which is subdivided into 9 cantons and thence into 102 communes.
History
The administrative district Territoire de Belfort was created under the terms of the 1871Treaty 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. There were three principal reasons for this exceptional treatment:
The population in and around Belfort was French-speaking.
With the loss of Alsace and the department of Moselle in Lorraine, France lost a number of well fortified and naturally favoured military positions that would otherwise have deterred future military aggression from the east. Belfort, on steep ground and lined up with the Vosges Mountains, would form part of a natural line of defence for France's newly imposed eastern frontier. This encouraged the politicians in Paris to hold out for its retention.
The Germans agreed primarily because the Prussian military officiers indicated that leaving it in France would give Germany a more defensible border. 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" or "Mont-Terrible", 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.
Economy
The departmental income of the department in 2008 had increased to €18 259 which was a little below the overall national figure. The averaged figure for the Territoire de Belfort masked relatively large disparities such as, in particular, that between Belfort itself at €15 431 and Bermont at €24 677.
Population and demography
In 2013 the department recorded a population of 144,318. Of these, slightly more than 50,000 live in the commune of Belfort itself. Four principal phases can be identified in the population trends during the two centuries between 1801 and 2000.
the period from 1800 to 1872 was marked by steady economic development and a relatively high birth rate. However, the cholera epidemic which in 1851 arose from increasing urbanisation, along with a more general economic slow-down, reduced the rate of increase in the third quarter of the century. Between 1803 and 1872 the recorded population increased from 37,558 to 56,781.
after the loss to Germany of most of Alsace in 1871, the Belfort population was boosted by the arrival of large numbers of refugees from "Germanisation": the years between 1871 and 1914 saw the development of large factories, with the mechanical and textile sectors being prominent growth areas. The population increase and the economic development were at their most intense in the Belfort conglomeration itself. By 1911 the territoire's population figure stood at 101,392.
in the years between 1914 and 1945 the economic narrative was dominated by two world wars and the period of stagnation that came between them. Population declined, having slipped to 86,648 in 1946.
after 1945 the region became a focus for industrial growth: population levels followed the same rising trend, to stand at 131,999 in 1982. Nevertheless, as in many parts of France, from about 1980 it was clear that the economic crisis of the 1970s was having a lasting effect in slowing the pace of expansion.
Geography
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, being the fifth smallest of France.
