What term describes the military governance that involves the suspension of ordinary law to protect Washington D.C.?

The term that describes the military governance involving the suspension of ordinary law to protect Washington D.C. is martial law. This legal concept typically arises in times of emergency when civilian authorities are unable to maintain order and security, leading to military control over the situation. In the context of Washington D.C., martial law allows military officials to enforce laws in place of civilian authority, ensuring the safety and security of the capital during crises.

Martial law is often invoked during significant national emergencies, including wars or civil unrest, where the regular functioning of government and civil law is deemed insufficient. It emphasizes the military's role in maintaining public order and governance, which aligns with historical instances where D.C. faced threats, necessitating direct military oversight to restore stability. Thus, the choice reflecting martial law accurately conveys this particular form of governance.
