 When the Dictator was away from Rome, the magister equitum usually remained behind to administer the city.The magister equitum, like the Dictator, had unchallengeable authority in all civil and military affairs, with his decisions only being overturned by the Dictator himself.The Dictatorship was definitively abolished in 44 BC after the assassination of Gaius Julius Caesar (Lex Antonia).
