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.
Julio-Claudian dynasty
Although Augustus' succession plans were all but ruined due to the deaths of more than several family members, including many of his own descendants, in the end Tiberius remained faithful to his predecessor's wishes that the next emperor would hail from the Julian side of the Imperial family. Thus, Tiberius was succeeded by Gaius Julius Caesar Augustus Germanicus, the sole-remaining son of his adopted son Germanicus. The new emperor not only belonged to both the Julian and Claudian sides of the Imperial family, but was also a direct descendant of Augustus Caesar through his mother Agrippina the Elder. More commonly remembered in history by his childhood nickname Caligula, he was the third Roman Emperor ruling from AD 37 to 41.
