Roman empire

By 47 BCE Caesar had won the civil war against Pompei, and soon became dictator, planning a major reconstruction of republican government. He was assassinated in 44, however, by a conspiracy of senators acting to save the Republic. Marcus Antonius then stepped forward as major claimant to power, while the Senate coalesced around Octavian, an heir listed in Caesar's will. After indecisive battles, the two put off final conflict in a second triumvirate, including Lepidus. Finally, the former two broke, and in 30 BCE, Octavian defeated Mark Antony at Actium. In the next twenty years, Octavian (now named Augustus) created the Principate, a new form of Roman government giving increased powers to a non-elective Princeps who would evolve into Emperor by the mid-first century CE.
