NSB

The Nationaal-Socialistische Beweging (national socialist movement) was founded in 1931 by Anton Mussert and became distinctly anti-Semitic in 1936 under the influence of Meinoud Rost van Tonningen. The party sided with Germany in World War II and at its height, in 1943, had over 100,000 members. The party was outlawed when Germany surrendered in May 1945. Mussert was executed in 1946.
