A state of emergency is a governmental declaration that announces that the country is in a state of emergency. This means that the government can suspend and/or change some functions of the executive, the legislative and or the judiciary during this period of time. It alerts citizens to change their normal behaviour and orders government agencies to implement emergency plans. A government can declare a state of emergency during a time of natural or man-made disaster, during a period of civil unrest, or following a declaration of war or situation of international/internal armed conflict.
