Solution:Political Parties: A sociological study of the Oligarch cal Tendencies of Modern Democracy by Robert Michels, First published in 1911, explores the internal dynamics and structure of political parties.
Michels argues that despite the democratic ideals parties may promote, they inevitably develop oligarchic structures, where power is concentrated in the hands of a few leaders rather than being distributed among the members.
He formulates the Iron Law of Oligarchy' which suggests that all organizations, inducing political parties, will eventually evolve into Wrenches, regardless of their original democratic intentions.
