Robert Michels

Robert Michels (; 9 January 1876 – 3 May 1936) was a German-born Italian sociologist who contributed to elite theory by describing the political behavior of intellectual elites.

He belonged to the Italian school of elitism. He is known best for his book ''Political Parties'', published in 1911, which contains a description of the "iron law of oligarchy". He was a friend and disciple of Max Weber, Werner Sombart and Achille Loria.

Politically, he transitioned from the Social Democratic Party of Germany to the Italian Socialist Party, endorsing the Italian revolutionary syndicalist group and later Italian Fascism. His ideas provided the basis of moderation theory which specifies the processes by which radical political groups are incorporated into an existing political system. Provided by Wikipedia
