Despotism is a form of government in which a single entity rules with absolute power. Normally, that entity is an individual, the despot, as in an , but societies which limit respect and power to specific groups have also been called despotic.
Colloquially, the word despot applies pejoratively to those who abuse 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.
The English dictionary defines despotism as "the rule of a despot; the exercise of absolute authority."
The root despot comes from the Greek word despotes, which means "master" or "one with power." The term has been used to describe many rulers and governments throughout history. It connoted the absolute authority and power exercised by the Pharaohs of Ancient Egypt, signified nobility in Byzantine courts, designated the rulers of Byzantine vassal states, and acted as a title for Byzantine Emperors. In this and other Greek or Greek influenced contexts, the term was used as an honorific rather than as a pejorative.
Due to its reflexive connotation throughout history, the word despot cannot be objectively defined. While despot is closely related to other Greek words like basileus and autokrator, these connotations have also been used to describe a variety of rulers and governments throughout history, such as local chieftains, simple rulers, kings, and emperors.
Of all the ancient Greeks, Aristotle was perhaps the most influential promoter of the concept of oriental despotism. He passed this ideology to his student, Alexander the Great, who conquered Persia, which at the time was ruled by the despotic Darius III, the last king of the Achaemenid dynasty. Aristotle asserted that oriental despotism was not based on force, but on consent. Hence, fear could not be said to be its motivating force, but rather the servile nature of those enslaved, which would feed upon the power of the despot master. Within ancient Greek society, every Greek man was free and capable of holding office; both able to rule and be ruled. In contrast, among the barbarians, all were slaves by nature. Another difference Aristotle espoused was based on climates. He observed that the peoples of cold countries, especially those of Europe, were full of spirit but deficient in skill and intelligence, and that the peoples of Asia, although endowed with skill and intelligence, were deficient in spirit and hence were subjected to slavery. Possessing both spirit and intelligence, the Greeks were free to govern all other peoples.
