political power
Emergency powers generally refers to the temporary suspension of the normal rules and proceedings in an organized political system and the provision of special discretionary authorities to a specific agent to respond to extraordinarily dangerous situations that threaten public safety. Such situations may include foreign invasion, internal rebellion, economic depression, or a severe natural disaster. [Source: The Encyclopedia of Political Science; Emergency Powers]
