On 26 June 1933, Himmler appointed SS-Oberführer Theodor Eicke as commandant of Dachau concentration camp, one of the first Nazi concentration camps.[92] It was created to consolidate the many small camps that had been set up by various police agencies and the NSDAP to house political prisoners.[93] The organizational structure Eicke instituted at Dachau stood as the model for all later concentration camps.[94] After 1934, Eicke was named commander of the SS-Totenkopfverbände (SS-TV), the SS formation responsible for running the concentration camps under the authority of the SS and Himmler.[95] Known as the "Death's Head Units", the SS-TV was first organized as several battalions, each based at one of Germany's major concentration camps.
