A thought-provoking dramatization of an actual classroom experiment on individualism vs. conformity in which a high school teacher formed his own "Reich" (called "The Wave") to show why the German people could so willingly embrace Nazism.

In the secular or religious world, mind control is the way to get the masses to react to a idea or movement. Movements will usually extol their superiority over others.

Uniqueness of the movement

Movements will usually extol their superiority over others. After all, there should be a strong reason to select that particular group.

It resulted in disastrous wars. [The Twenty Years War, The Forty Years War...]
