A more thorough explanation: Martial law is a law administered by the military rather than a civilian government, typically in a time of emergency when civilian authorities are unable to maintain order and public safety. It involves the suspension of ordinary law and the imposition of military authority over a designated area or region.
Example: During times of extreme crisis, the government may declare martial law to maintain order and security.
