The Nationalsozialistische Volkswohlfahrt (NSV), meaning "National Socialist People's Welfare" was a social welfare organization during the Third Reich. The NSV was established in 1933, shortly after the NSDAP took power in Germany. Its seat was in Berlin. The structure of the NSV was based on the Nazi Party model, with local, county (Kreis) and group administrations. Erich Hilgenfeldt, who worked as office head at the NSV, organized a charity drive to celebrate Hitler's Birthday on April 20, 1931. Following this move Joseph Goebbels named him the leader of the NSV. The NSV became established as the single Nazi Party welfare organ in May 1933.
