Militant League for German Culture
Repeatedly, Spann tried to draw the ruling powers' attention to his authoritarian theory of a corporate state, which he thought should be introduced immediately for the benefit of all. In 1928, he joined the Militant League for German Culture. Around 1930, he also joined the Nazi Party. In 1933 the Austro-Hungarian social philosopher Karl Polanyi wrote that Spann had given Fascism its first comprehensive philosophical system, and that his idea of "anti-individualism" had become its guiding principle.
