Augustus

[close] Caesar Augustus (born Gaius Octavius; 23 September 63 BC – 19 August AD 14), also known as Octavian, was the founder of the Roman Empire; he reigned as the first Roman emperor from 27 BC until his death in AD 14.[a] The reign of Augustus initiated an imperial cult as well as an era associated with imperial peace, the Pax Romana or Pax Augusta, in which the Roman world was largely free of armed conflict aside from expansionary wars and the Year of the Four Emperors. The Principate system of imperial rule established by Augustus lasted until the Crisis of the Third Century.

Gaius Octavius was born into an old and wealthy equestrian branch of the plebeian gens Octavia. His maternal great-uncle Julius Caesar was assassinated in 44 BC, and Octavius was named in Caesar's will as his adopted son and heir; as a result, he inherited Caesar's name, estate, and the loyalty of his legions. He, Mark Antony and Marcus Lepidus formed the Second Triumvirate to defeat the assassins of Caesar. Following their victory at the Battle of Philippi (42 BC), the Triumvirate divided the Roman Republic among themselves and ruled as de facto dictators. The Triumvirate was eventually torn apart by the competing ambitions of its members; Lepidus was exiled in 36 BC, and Antony was defeated by Octavian at the Battle of Actium in 31 BC. Antony and his wife Cleopatra, the Ptolemaic queen of Egypt, killed themselves during Octavian's invasion of Egypt, which then became a Roman province.

After the demise of the Second Triumvirate, Augustus restored the outward façade of the free republic, with governmental power vested in the Roman Senate, the executive magistrates and the legislative assemblies, yet he maintained autocratic authority by having the Senate grant him lifetime tenure as commander-in-chief, tribune and censor. A similar ambiguity is seen in his chosen names, the implied rejection of monarchical titles whereby he called himself Princeps Civitatis (First Citizen) juxtaposed with his adoption of the title augustus.

Augustus dramatically enlarged the empire, annexing Egypt, Dalmatia, Pannonia, Noricum and Raetia, expanding possessions in Africa, and completing the conquest of Hispania, but he suffered a major setback in Germania. Beyond the frontiers, he secured the empire with a buffer region of client states and made peace with the Parthian Empire through diplomacy. He reformed the Roman system of taxation, developed networks of roads with an official courier system, established a standing army, established the Praetorian Guard as well as official police and fire-fighting services for Rome, and rebuilt much of the city during his reign. Augustus died in AD 14 at age 75, probably from natural causes. Persistent rumors, substantiated somewhat by deaths in the imperial family, have claimed his wife Livia poisoned him. He was succeeded as emperor by his adopted son Tiberius, Livia's son and former husband of Augustus' only biological child Julia.
