Strasserism (German: Strasserismus) is an ideological strand of Nazism which adheres to revolutionary nationalism and to economic antisemitism, which conditions are to be achieved with radical, mass-action and worker-based politics that are more aggressive than the politics of the Hitlerite leaders of the Nazi Party. Named after brothers Gregor and Otto Strasser, the ideology of Strasserism is a type of Third Position, right-wing politics in opposition to Communism and to Hitlerite Nazism.
In his political career, Otto Strasser led an ultranationalist faction within the Nazi Party, but resigned from the Party in 1930; he later established the Combat League of Revolutionary National Socialists (the Black Front) to rival the Nazi Party.[1] Consequent to his politics, Otto Strasser fled Germany in 1933 and returned to West Germany after the end of World War II in 1953. In the intramural politics of the Nazi Party, Strasserism had many supporters among the troops of the Sturmabteilung (SA), which led to Hitler's purging the Strasserist faction and killing their leader, Gregor Strasser, as well as Ernst Röhm, the head of the SA, during the Night of the Long Knives in July 1934.
In the 1980s, the revolutionary nationalism and the economic anti-Semitism of Strasserism reappeared in the politics of the National Front in the United Kingdom.[2]
