Army rule, also known as military rule or martial law, refers to the governance of a country or region by the military. Some common synonyms for army rule include junta, regime, dictatorship, and autocracy. These terms all refer to forms of authoritarian rule, where power is concentrated in the hands of a small group or individual. Other synonyms may depend on the specific context in which army rule is being used. For example, if referring to a particular period of history, such as the military dictatorship in Chile under Augusto Pinochet, the term "Pinochet regime" may be used instead of "army rule".
