An autocracy is a system of government in which a supreme power is concentrated in the hands of one person, whose decisions are subject to neither external legal restraints nor regularized mechanisms of popular control (except perhaps for the implicit threat of coup d'état or mass insurrection).
History and etymology 
This use remains current in the modern Greek language, where the term is used for anyone holding the title "emperor", regardless of the actual power of the monarch. Some historical Slavic monarchs, such as Russian tsars and emperors, included the title "Autocrat" as part of their official styles, distinguishing them from the constitutional monarchs elsewhere in Europe.
Comparison with other forms of government 
Both totalitarianism and military dictatorship are often identified with, but need not be, an autocracy. Totalitarianism is a system where the state strives to control every aspect of life and civil society. It can be headed by a supreme dictator, making it autocratic, but it can also have a collective leadership such as a commune or political party.
Because autocrats need a power structure to rule, it can be difficult to draw a clear line between historical autocracies and oligarchies. Most historical autocrats depended on their nobles, the military, the priesthood or other elite groups.
