Romulus Augustulus
Flavius Romulus Augustus (c. AD 460 – after AD 476; possibly still alive as late as AD 507), known derisively and historiographically as Romulus Augustulus, was the Roman emperor who ruled the Western Roman Empire from 31 October 475 until 4 September 476. He is often described as the "last Western Roman emperor", though some historians consider this to be Julius Nepos. His deposition by Odoacer traditionally marks the end of the Roman Empire in the West, the end of Ancient Rome, and the beginning of the Middle Ages in Western Europe.
Final War of the Roman Republic
Cleopatra did not immediately follow Antony in suicide. Instead, in a last-ditch effort, Cleopatra opened negotiations with Octavian. Cleopatra begged Octavian to spare Caesarion’s life in exchange for willing imprisonment. Octavian refused. Within a week, Octavian informed Cleopatra that she was to play a role in Octavian's Triumph back in Rome. This role was "carefully explained to her", while Caesarion was "butchered without compunction". Octavian supposedly said "two Caesars are one too many" as he ordered Caesarion's death. According to Strabo who was alive at the time of the event, Cleopatra died from a self-induced bite from a venomous snake, or from applying a poisonous ointment to herself. Learning of Cleopatra's death, Octavian had mixed feelings. He admired the bravery of Cleopatra, and gave her and Antony a public military funeral in Rome. As they left Alexandria, a new age dawned when Rome annexed Egypt. With Cleopatra's death, the final war of the Republic was over.
Within a month, Octavian was named Pharaoh, and Egypt became his personal possession. By executing Antony's supporters, Octavian finally brought a century of civil war to a close. In 27 BC Octavian was named Augustus by the Senate and given unprecedented powers. Octavian, now Augustus, transformed the Republic into the Roman Empire, ruling it as the first Roman emperor.
