In 1929, the SS-Hauptamt (main SS office) was expanded and reorganized into five main offices dealing with general administration, personnel, finance, security, and race matters. At the same time, the SS-Gaus were expanded into three SS-Oberführerbereiche areas, namely the SS-Oberführerbereich Ost, SS-Oberführerbereich West, and SS-Oberführerbereich Süd.[25] The lower levels of the SS remained largely unchanged.
