Comparing control: "totalitarianism" vs. "authoritarianism"

What is similar?

Both totalitarianism and authoritarianism refer to forms of government that concentrate power in the hands of a leader or a small elite that is not constitutionally responsible to the public. They both suppress political dissent and limit individual freedoms. Both systems often employ propaganda and control over the media to maintain their power.

What is different?

Totalitarianism is an extreme form of authoritarianism characterized by an attempt to control all aspects of life, including the economy, education, art, science, and private life. A totalitarian regime seeks to dominate every aspect of social and political life to an unprecedented degree. Authoritarianism, on the other hand, is marked by strong central power and limited political freedoms but may allow some individual and social freedoms, provided they do not threaten the regime. In authoritarian systems, political control is paramount, but total domination over all aspects of society as seen in totalitarianism is not necessarily pursued.
