The concept was adopted by Adolf Hitler, who upon the Nazi seizure of power in 1933 appointed Konstantin Hierl state secretary in the Reich Ministry of Labour, responsible for FAD matters. Hierl was already a high-ranking member of the NSDAP and head of the party's labour organisation, the Nationalsozialistischer Arbeitsdienst or NSAD. Hierl developed the concept of a state labour service organisation similar to the Reichswehr army, with a view to implementing a compulsory service.
