Strasserism refers to a political movement, which emerged from the NSDAP, deriving its name from the Strasser brothers; Otto Strasser and Gregor Strasser. The movement was more socialistic than some of the older conservative, military and aristocratic elements in the government, with Adolf Hitler falling somewhere inbetween both camps. They called for a "second revolution" after the NSDAP had gained the state. Joseph Goebbels had initially been close to the Strasser brothers, but became more loyal to the Führer.
They promoted concepts such as "class conflict" and a warmer position on the Soviet Union. After being expelled from the NSDAP in 1930, Otto Strasser founded the Black Front, known in full as the Combat League of Revolutionary National Socialists and based in Berlin. Elements sympathetic to the Strasserite position were executed during the Night of the Long Knives in 1934, including Otto's older brother Gregor. The movement had somewhat of a revival in influence peaking between the late 1960s and 1980s, especially among various nationalist movements in Germany, the United Kingdom, the Netherlands, Italy and France.
