An absolute ruler or autocrat; a variant or historical term for an autonomous or self-ruling authority.
From Greek 'auto-' (self) + 'kratos' (power, strength). Related to 'autocrat,' this represents the Greek root form more directly. Historical and occasionally literary usage.
Byzantine emperors loved the title 'autokrator' because it literally meant 'one who rules by their own power'—modern 'autocrat' lost the Greek precision when filtered through Latin and French.
