ACTIUM
◼
31 BCE
The assassination of Julius Caesar in
44
BCE unleashed a violent struggle between
the Republican partisans of his killers, Brutus
and Cassius, and the defenders of Caesar’s
legacy, notably Octavian (his adopted son)
and Mark Antony. Relations between Antony
and Octavian deteriorated. Accusations that
Antony had promised his mistress Cleopatra VII of Egypt the cession
of several Roman provinces led to a nal rupture with the Roman
Senate, which declared war on Antony and Cleopatra in 33
BCE.
Octavian gathered an army and sailed for Greece to gain control
over Antony. By September 31
BCE, he and his deputy Agrippa had
seized key garrisons loyal to Antony and positioned themselves with
a eet of 230 ships north of the Gulf of Ambracia, where Antony’s
smaller eet of 170 vessels was moored. Antony resolved to break
out to save what he could and, on September 2, sailed out to open
water. His vessels engaged Octavian’s squadrons, allowing Cleopatra
to get away with their treasure. Antony then broke o with a small
otilla, leaving the rest of his navy to ght an increasingly desperate
struggle. Surrounded by Octavian’s marines, Antony’s heavy
ships were rammed, boarded, or set alight. His land force rapidly
surrendered, and by the summer of 30
BCE, when Octavian arrived
in Egypt, Antony had virtually no forces left. Faced with certain
defeat, he and Cleopatra committed suicide, leaving Octavian
the unchallenged master of Rome.

OCTAVIAN VS. MARK ANTONY AND EGYPT
REPUBLICAN CIVIL WAR
Octavian’s victory at Actium enabled him to reshape
the Roman world. In 27
BCE, he induced the Senate to
grant him unprecedented powers: personal control over
key provinces, successive consulships, and the title
Augustus (meaning “venerable”). These changes marked the
shift of Rome from a Republic to an Empire, and Augustus’s
reorganization of the army (he dismissed legions previously
loyal to his competitors) rendered it answerable to him alone.
During his reign, his troops pushed the Roman border beyond
the Rhine in Germany and to the Danube in the Balkans. His
political authority, augmented by the right to propose and
veto legislation, enabled him to bequeath his position to
his stepson Tiberius, the second emperor, in 14
CE.
