The National Socialist Freedom Movement (German: Nationalsozialistische Freiheitsbewegung, NSFB) or National Socialist Freedom Party (Nationalsozialistische Freiheitspartei, NSFP) was a far-right, ultranationalist, and antisemitic political party in Weimar Germany which existed from April 1924 to February 1925.
After the failure of the Beer Hall Putsch, a Nazi coup attempt, the Nazi Party (NSDAP) was banned in Germany and most of its leadership was either imprisoned or forced into exile. This led some of its remaining members, including one Erich Ludendorff, to form the NSFB as a legal means of carrying on the party's legacy and ideology.
During the 1924 Bavarian state election as well as May and December 1924 federal elections, the NSFB formed an electoral alliance with the German Völkisch People's Party (another small, far-right party which had split from the German National People's Party).
After Nazi Party leader Adolf Hitler was released from prison and the ban on the Nazi Party had expired, the Nazi Party was re-established. The NSFB was then absorbed into the NSDAP.
