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 is akin to the Latin phrase mobile vulgus meaning "the fickle crowd," from which the term "mob" originally derives.
As a term in civics it implies that there is no formal authority whatsoever, not even a commonly accepted view of anarchism, and so disputes are raised, contended and closed by brute force − might makes right, but only in a very local and temporary way, as another mob or another mood might just as easily sway a decision. It is often associated with demagoguery and the rule of passion over reason. It may be considered an ad hoc democracy
