War of Actium

• 1. Triumvirate Power Struggle

  ›

  In 42 BC, the Battle of Philippi ended with the defeat of Marcus Junius Brutus and Gaius Cassius Longinus. This victory allowed Octavian, Antony, and Marcus Lepidus to fill the power vacuum left by Julius Caesar's assassination. The Second Triumvirate divided control over the Roman world shortly after this battle. Octavian took command of Hispania, Gaul, Italia, and Africa in the west. Antony received Graecia, Asia, Syria, and Aegyptus in the east. Peace held for a time while Octavian suppressed revolts and Antony reorganized eastern territories. However, the alliance fractured when Antony began an affair with Cleopatra, queen of Egypt. Romans noticed his actions, especially Octavian, who sought to destroy his rival. By 36 BC, Lepidus had been expelled from the triumvirate, leaving only two men holding supreme power.

• 2. Propaganda And Senate Politics

  ›

  Octavian seized Antony's will from the Temple of Vesta without legal authority. He read aloud how Antony left all money to children born of Cleopatra. The document stated these children would rule kingdoms carved from Roman territory. Senators were outraged that Antony wanted burial in Alexandria instead of Rome. In 32 BC, Antony married Cleopatra after divorcing Octavia, Octavian's sister. This act combined with plans for a second senate in Alexandria created perfect conditions for political destruction. Nearly all Romans felt astonished by the Donations of Alexandria. Antony ceded much eastern territory to Cleopatra and crowned her queen of kings. Caesarion became king of kings, Alexander Helios ruler of Armenia, Media, and Parthia. Cleopatra Selene II received Cyrenaica and Libya. Ptolemy Philadelphus ruled Phoenicia, Syria, and Cilicia. Octavian blamed Cleopatra, not Antony, when the Senate declared war on Egypt alone. Forty percent of senators fled Rome to join Antony's cause alongside both consuls.

• 3. Naval Strategy At Actium

  ›

  By mid-31 BC, Antony moved his army into Greece while Octavian followed. Marcus Vipsanius Agrippa commanded Octavian's naval forces as chief military adviser. Antony's fleet consisted of large vessels with inexperienced crews and commanders. Octavian's smaller ships carried experienced sailors who had fought years of Roman naval combat. Agrippa disrupted Antony's supply lines before the main engagement. Gaius Sosius defeated Lucius Arruntius' squadron but was later forced to flee after Tarcondimotus I died. On the 2nd of September 31 BC, Antony moved 290 quinqueremes through the strait into open sea. Octavian countered with 350 Liburnian ships that were lighter and more maneuverable. Cleopatra stayed behind Antony's line on her royal barge during the initial phase. One former general delivered Antony's battle plan directly to Octavian. Mid-day came when Antony extended his line beyond shore protection. Octavian's fresh crews rammed enemy ships while showering arrows and catapult stones down from above. A gap opened in Agrippa's blockade allowing Cleopatra to escape with her squadron. Antony led a breakthrough attempt that initially succeeded before Agrippa attacked both flanks. By day's end, almost Antony's entire fleet lay at the bottom of the sea.

• 4. The Fall Of Alexandria

  ›

  After losing control of the sea, Antony's legations surrendered without fighting within a week. Octavian rejected transporting troops across water and instead marched by land through Asia in early 30 BC. Antony had secured backing from Rome's client kingdoms in the east. Lucius Pinarius switched loyalty to Octavian and moved four legions toward Alexandria. Antony attempted to gather an army in Cyrenaica but failed when Pinarius defected. Trapped in Egypt with remnants of their forces, Antony and Cleopatra awaited Octavian's arrival. Before Octavian reached the city, Antony attacked Pinarius with roughly 30,000 soldiers. He was outnumbered two to one and lost what remained of his army. On the 1st of August 30 BC, Antony fell on his sword according to Roman tradition. An open wound in his belly left him alive long enough to be carried into Cleopatra's mausoleum. She fled there after negotiations with Octavian failed to save Caesarion's life. Octavian ordered Caesarion executed while promising Cleopatra a role in his triumph. Strabo recorded that Cleopatra died from a venomous snake bite or poisonous ointment applied to herself.

• 5. Birth Of The Empire

  ›

  Within a month of Cleopatra's death, Octavian became pharaoh and claimed Egypt as personal property. In 27 BC, the Senate named him Augustus and granted unprecedented powers. Laws passed over subsequent years preserved republican appearances while concentrating authority in one man. Critical border provinces like Syria, Egypt, and Gaul were directly ruled by Augustus and successors. The senate retained nominal power over senatorial provinces but lost control of military strongholds. From then onward, Rome would be governed by a princeps, meaning first citizen. Three emperors in the 1st century AD, Caligula, Claudius, and Nero, were direct descendants of Antony. The empire lasted until Rome fell in the 5th century AD in Western Europe. The eastern part survived as Byzantium until Constantinople collapsed in AD 1453. A period called Pax Romana brought peace for centuries after Augustus' death. This era marked the end of civil wars that had plagued Rome for over a hundred years.
