The imperial consulate during the period of the High Empire (until the 3rd century) was an important position, albeit as the method through which the Roman aristocracy could progress through to the higher levels of imperial administration – only former consuls could become consular legates, the proconsuls of Africa and Asia, or the urban prefect of Rome. It was a post that would be occupied by a man halfway through his career, in his early thirties for a patrician, or in his early forties for most others. Emperors frequently appointed themselves, or their protégés or relatives, consuls, even without regard to the age requirements. For example, Emperor Honorius was given the consulship at birth. Cassius Dio states that Caligula intended to make his horse Incitatus consul, but was assassinated before he could do so.
