Despotism

Despotism (Greek: Δεσποτισμός, despotismós) is a form of government in which a single entity rules with absolute power. Normally, that entity is an individual, the despot; but (as in an autocracy) societies which limit respect and power to specific groups have also been called despotic.

Colloquially, the word despot applies pejoratively to those who use their power and authority to oppress their populace, subjects, or subordinates. More specifically, the term often applies to a head of state or government. In this sense, it is similar to the pejorative connotations that are associated with the terms tyrant and dictator.
