Ochlocracy

Ochlocracy (Greek: οχλοκρατία or okhlokratía; Latin: ochlocratia) is government by mob or a mass of people, or the intimidation of constitutional authorities. In English, the word mobocracy is sometimes used as a synonym. As a pejorative for majoritarianism, it's akin to the Latin phrase mobile vulgus meaning "the easily moveable crowd," from which the term "mob" originally derives.
