Autokrator or Autocrator (Ancient Greek: αὐτοκράτωρ, romanized: autokrátōr, lit. 'self-ruler', from αὐτός, autós, 'self' + κράτος, krátos, 'dominion') is a Greek epithet applied to an individual who is unrestrained by superiors. It has been applied to military commanders-in-chief as well as Roman and Byzantine emperors as the translation of the Latin title imperator. Its connection with Byzantine-style absolutism gave rise to the modern terms autocracy and autocrat.
