Augustus
“Caesar's adopted heir, who won Rome's civil wars at Actium and, as Augustus, turned the Republic into a monarchy in republican dress: the first Roman emperor.”
Augustus was the first Roman emperor. He was born Gaius Octavius in Rome on 23 September 63 BCE, the son of a senator from the small town of Velitrae and of Atia, a niece of Julius Caesar, and it was Caesar who launched him: the boy gave the funeral speech for his grandmother Julia at twelve, took part in Caesar's triumph in 46 and followed him to Spain in 45. In March 44 he was studying at Apollonia, across the Adriatic, when Caesar was murdered. Caesar's will made the eighteen-year-old his adopted son and chief heir. Against his family's advice he took up the inheritance and the name that came with it, and from then on called himself simply Caesar; historians call him Octavian until 27 BCE.
The next fourteen years were civil war. At nineteen he raised a private army from Caesar's veterans, which the Senate, led by Cicero, made legal so that he could fight Mark Antony; then he turned on the Senate, took the consulship by force, and in November 43 joined Antony and Lepidus as triumvirs, a junta that began by killing its enemies, Cicero among them. At Philippi in October 42 Antony and he destroyed Brutus and Cassius, Caesar's murderers. Antony took the East and Octavian the West. With his friend Agrippa as admiral he beat Sextus Pompey at Naulochus in 36 and pushed Lepidus aside. His rivalry with Antony, now Cleopatra's partner, ended in war: on 2 September 31 Agrippa's fleet won at Actium, and in August 30 Octavian took Alexandria, where Antony and Cleopatra killed themselves. Egypt became a Roman province, and he was the last man standing.
He spent the next forty-four years making one-man rule look like a restored republic. In January 27 BCE he handed his powers back to the Senate, was given command of the provinces where most of the legions stood, and received a new name, Augustus, 'the revered one'. Consuls, Senate and elections went on, but from 23 BCE he held a tribune's powers and a command that overrode every governor's, and the army, now 28 standing legions paid and pensioned by him alone, swore its oath to him. He called himself princeps, the first citizen. Inside the frontiers came the Pax Romana: the Parthians gave back the standards lost by Crassus in 20 BCE without a battle, and Spain, the Alps and the Danube lands were conquered, though three legions were lost in Germany under Varus in 9 CE. Suetonius says he found Rome a city of brick and left it a city of marble; Virgil, Horace and Livy wrote in his Rome.
What he could never settle was who came next. He had one child, his daughter Julia, and the heirs he chose died one after another: his nephew Marcellus, his friend Agrippa, his grandsons Gaius and Lucius. In 4 CE he adopted his stepson Tiberius, the son of his wife Livia. Augustus died at Nola on 19 August 14 CE, a month short of seventy-six, and Tiberius took over without a fight. His own account of his deeds, the Res Gestae, was set up in bronze outside his Mausoleum, and the Senate made him a god. Every later emperor took his name, the month of August still carries it, and the system he built held the Mediterranean world together for centuries. Jesus was born in his reign.
