No dictatorship is a form of government. Anarchism means no leaders in Greek. A dictator which is the ruler in a dictatorship is an authoritarian ruler who assumes sole and absolute power, without a blood line (hereditary or king and queen). Iraq when Saddam was in power it was a dictatorship, but the people elected him into power. The dictator has full power on the government, the state, and the military.
