Autocracy is a form of government in which absolute power is held by one person, known as an autocrat. It includes both absolute monarchies and dictatorships, while it is contrasted with democracy and other forms of free government. The autocrat has total control over the exercise of civil liberties within the autocracy, choosing under what circumstances they may be exercised, if at all. Governments may also blend elements of autocracy and democracy, forming a mixed type of regime sometimes referred to as anocracy, hybrid regime, or electoral autocracy. The concept of autocracy has been recognized in political philosophy since ancient history.
Autocrats maintain power through political repression of any opposition and co-optation of other influential or powerful members of society. The general public is controlled through indoctrination and propaganda, and an autocracy may attempt to legitimize itself in the eyes of the public through appeals to political ideology, religion, birthright, or foreign hostility. Some autocracies establish legislatures, unfair elections, or show trials to further exercise control while presenting the appearance of democracy. The only limits to autocratic rule are practical considerations in preserving the regime. Autocrats must retain control over the nation's elites and institutions for their will to be exercised, but they must also prevent any other individual or group from gaining significant power or influence. Internal challenges are the most significant threats faced by autocrats, as they may lead to coups d'état.
