Answer
In 1920, Dimitrije Ljotić left active service in the Serbian Army to pursue politics. He was a member of the Serbian Radical Party, and he served as a member of the Serbian Parliament from 1923 to 1929. In 1929, the Serbian Radical Party was banned by King Aleksandar Karađorđević, and Ljotić was forced to flee the country. He settled in Vienna, where he became involved in the Serbian nationalist movement.
