The Austrian DNSAP split into two factions in 1923, the Deutschsozialen Verein (German Social Association) led by Dr. Walter Riehl, and the Schulz-Gruppe (Karl Schulz).

After 1930, most former DNSAP members became supporters of the German NSDAP led by Hitler, and were one of the chief elements leading the pro-Nazi coup in 1938 that brought about the Anschluss with Germany.
