Born at Windsheim in Bavaria, Otto Strasser took an active part in World War I. On 2 August 1914 he joined the Bavarian Army as a volunteer. He rose through the ranks to lieutenant and was twice wounded.[1] He returned to Germany in 1919 where he served in the Freikorps that put down the Bavarian Soviet Republic which was organized on the principles of workers' councils. At the same time, he also joined the Social Democratic Party. In 1920 he participated in the opposition to the Kapp Putsch. However, he grew increasingly alienated with that reformist-socialist party's stand, particularly when it put down a workers' uprising in the Ruhr, and he left the party later that year. In 1925 he joined the NSDAP, in which his brother had been a member for several years, and worked for its newspaper as a journalist, ultimately taking it over with his brother. He took the 'socialist' element in the party's programme seriously enough to lead a very socialist-inclined faction of the party in northern Germany together with his brother Gregor and Joseph Goebbels. His faction advocated support for strikes, nationalisation of banks and industry, and — despite acknowledged differences — closer ties with the Soviet Union. Some of these policies were opposed by Hitler, who thought they were too radical and too alienating from parts of the German people (middle class and some Nazi-supporting nationalist industrialists in particular), and the Strasser faction was defeated at the Bamberg Conference (1926), with Joseph Goebbels joining Hitler. Humiliated, he nonetheless, along with his brother Gregor, continued as a leading Left Nazi within the Party, until expelled from the NSDAP by Hitler in 1930.
