The office traces its origins to 1931 when the SS created the SS-Amt to serve as an SS Headquarters staff overseeing the various units of the "Allgemeine-SS" (General SS). In 1933, after the Nazi Party came to power, the SS-Amt was renamed the "SS-Oberführerbereichen" and placed in command of all SS units within Nazi Germany. This agency then became the SS-HA on January 30, 1935. The organization oversaw the "Allgemeine-SS", concentration camps, the "SS-Verfügungstruppe" (Special-purpose troops), and the "Grenzschutz" (Border Control regiments).
