Ideology Of Monarchy
…The Roman Empire had a well-formulated ideology and institutions of monarchy, and by the late Empire this was an absolute monarchy. Emperors could not always do just what they wanted to do, of course, but the system operated as though the imperial will were all-powerful; no constitutitional mechanism existed to frustrate or modify it. In any premodern absolute monarchy, effective limitations were set by primitive communications networks and by the small size of the civil service, which frequently made it impossible to implement the royal will even when it was accepted as law. The ideology of absolute monarchy was developed out of a Roman law, based on Hellenistic and Oriental traditions, that held that the people had surrendered the natural powers to the monarch and could never revoke the surrender.
