Idea

Robert Michels argued that organisation itself produces oligarchy: those who build and run an organisation gain control over it, whatever its democratic ideals.

Theory

In Political Parties (1911) he drew chiefly on the socialist parties of his day. Britannica notes that organisational needs such as rapid decision-making and full-time activity drive the tendency. Complexity favours leaders with expertise, time and control of communication, while ordinary members defer.

Real examples

Michels's own cases were socialist parties and trade unions. The thesis is now also invoked in debates over concentrated voting power in large membership organisations and token-governed DAOs.

Critique

Lipset, Trow and Coleman (1956) studied the International Typographical Union, whose institutionalised two-party competition is cited as a counterexample. Michels himself later saw elite rule as inevitable and even desirable and did not oppose Fascism.

Results

A founding text of elite theory and political sociology. Most scholars treat it as a tendency whose strength depends on organisational design, not a law.
