In 1800 the arrondissements of Colmar, Altkirch, Belfort, Delémont and Porrentruy were established. In 1814 the arrondissements of Delémont and Porrentruy were disbanded (ceded to Switzerland). In 1857 Mulhouse replaced Altkirch as subprefecture. In 1871 most of the department was ceded to Germany, except the Territoire de Belfort that remained French. In 1919 the department of Haut-Rhin was restored, with the arrondissements of Colmar-Ville, Colmar-Campagne, Altkirch, Guebwiller, Mulhouse, Ribeauvillé and Thann. In 1934 the arrondissements of Colmar-Ville and Colmar-Campagne were merged into the new arrondissement of Colmar.[2]
The borders of the arrondissements of Haut-Rhin were modified in January 2015:[3]
all 62 communes of the former arrondissement of Colmar to the new arrondissement of Colmar-Ribeauvillé
