Dictatorship: 

Dictatorship refers to such an administration of a person or a group of persons who forcibly take control of the governance of the state and use it in an unrestricted way. In this system of governance, the administration becomes all powerful, autocratic and free – willing. It controls other people in a psychological way and oppresses their emotions, desires and liberties. The spirit of justice, equality and freedom does not exist in it. In this system, common people are put under restrictions. Those persons, who refuse to comply with the dictate of the rules, are dealt with cruelly. It is against the democratic doctrines.

Aristocracy: 

Aristocracy is such a system of administration, wherein state governance is cent-red in the hands of some high-born persons who have hobble qualities.. In Greece, the system of aristocracy was a recognised system. Plato and Aristotle have described this in detail. In this system, the citizens remain quite distant from the governing class. In aristocracy, laws are all pervasive. State and government are operated on the basis of intellect, ability and culture.
