Through Regions of France, Germany and Switzerland

On 1 January 2021, the départemental collectivities of Bas-Rhin and Haut-Rhin were merged into the European Collectivity of Alsace.

History

Haut-Rhin is one of the original 83 départements, created during the French Revolution, on 4 March 1790 through the application of the law of 22 December 1789 in respect of the southern half of the province of Alsace (Haute-Alsace).

Its boundaries have been modified many times:

  • 1798, it absorbed Mulhouse, formerly a free city, and the last Swiss enclave in the south of Alsace;
  • 1800, it absorbed the whole département of Mont-Terrible;
  • 1814, it lost the territories which had been part of Mont-Terrible, which were returned to Switzerland, except for the former County of Montbéliard;
  • 1816, it lost Montbéliard, which was transferred to the département of Doubs;
  • 1871, it was mostly annexed by the German Empire (Treaty of Frankfurt); the remaining French part formed the Territoire de Belfort in 1922;
  • 1919, it was reverted to France (Treaty of Versailles) but remains administratively separated from Belfort.
  • 1940, it was annexed de facto by Nazi Germany.
  • 1944, it was recovered by France.
