Reich Defense Commissioner (German: Reichsverteidigungskommissar, RVK) was a governmental position created in Nazi Germany at the outbreak of World War II on 1 September 1939. Charged with overall defense of the territory of the German Reich, there was originally one Reich Defense Commissioner for each of 15 Wehrkreise (Military Districts). On 16 November 1942, the geographical scope was reduced to the Gau level, raising the number of Reich Defense Commissioners to 42.
