Augustus
Augustus (; 23 September 63 BC – 19 August AD 14) was a Roman statesman and military leader who was the first Emperor of the Roman Empire, controlling Imperial Rome from 27 BC until his death in AD 14. His status as the founder of the Roman Principate has consolidated an enduring legacy as one of the most effective and controversial leaders in human history.
Crisis of the Roman Republic
The end of the Crisis can likewise either be dated from the assassination of Julius Caesar on 15 March 44 BC, after he and Sulla had done so much "to dismantle the government of the Republic," or alternately when Octavian was granted the title of "Augustus" by the Senate in 27 BC, marking the beginning of the Roman Empire. The end could also be dated "earlier", to the time of the constitutional reforms of Julius Caesar in 49 BC.
