Edicts are few and far between in a democracy, since very few important laws can be made by a president or prime minister acting alone. But when a crisis arose in the Roman Republic, the senate would appoint a dictator, who would have the power to rule by edict. The idea was that the dictator could make decisions quickly, issuing his edicts faster than the senate could act. When the crisis was over, the edicts were canceled and the dictator usually retired from public life. Things are different today: dictators almost always install themselves in power, and they never give it up.
