Despotism

Despotism is a form of government in which a single entity, called the despot, rules with absolute power. That entity may be an individual, as in an autocracy, or it may be a group, as in an oligarchy. The word despotism means to "rule in the fashion of a despot" and should not be confused with "despot", an individual.

Colloquially, despot has been applied pejoratively to a person, particularity a head of state or government, who abuses his power and authority to oppress his people, subjects or subordinates

One of the first Despotism came in a more theocratic form in Akhasan, where the king was considered to be the son of god.
