Reichskommissariat of Belgium and Northern France

The Reichskommissariat of Belgium and Northern France was a German civil administration (Zivilverwaltung) which governed German-occupied Belgium during World War II. The Reichskommissariat replaced an earlier military government, the Military Administration in Belgium and Northern France, established in the same territory in 1940. On 18 July 1944, the first Gauleiter, Josef Grohé, was named the first Reichskommissar of the territory, known as the Reichskommissariat Belgien und Nordfrankreich or Reichskommissariat für die besetzten Gebiete von Belgien und Nordfrankreich.

The territory was mostly liberated by the Allies in September 1944, so the existence of the territory was extremely short lived. Following the liberation, the territory was retrospectively annexed directly into Germany (although no longer under de facto German control) as three separate Reichsgaue: Reichsgau Flandern, Wallonien and the Brussels district
