Bezirk Lothringen (today's French: link=no|Présidence <ref>F. ROTH La Présidence de Lorraine dans l’Empire allemand de 1871 à 1918, Annales de l’Est, Mémoire n° 50, Nancy, 1976, Moulin-les-Metz, 720 pages</ref> de la Lorraine, at the time translated into French: link=no|Département de la Lorraine[1] i.e. Department of Lorraine), also called German Lorraine (Deutsch Lothringen), was a government region ("Bezirk") in the western part of Alsace-Lorraine when it was part of the German Empire from 1871 to 1918.
The Department of Lorraine differed from other Prussian government regions, as it was not a simple governorate. As a corporation of self-rule of the pertaining rural and urban districts and cantons, it was similar to regions in the then neighbouring Bavaria (Palatinate), which had been formed after the French model départements into which that region had been divided under French annexation. Thus the district parliaments delegated deputies to the General Council (parliament), the Bezirkstag von Lothringen (French: link=no|Conseil Général de la Lorraine). The capital of the Department of Lorraine was Metz.
The department comprised the districts ("Kreise") of :
The department of Lorraine corresponds exactly to the current département of Moselle. After the outbreak of the Second World War and the defeat of France in 1940, the département of Moselle, renamed CdZ-Gebiet Lothringen, was added to the Gau Westmark on 30 November 1940.[3]
