Timeline
Octavian’s Triple Triumph
Octavian celebrates his victory in Rome with three days of triumphal processions, displaying spoils and prisoners from Egypt. The ceremonies mark the symbolic end of the Republic and the beginning of the Empire.
Location: Rome, Italy
Octavian Invades Egypt
Octavian’s legions cross into Egypt, quickly overwhelming the last loyalist forces. The advance is marked by looting and the execution of Egyptian officials.
Location: Pelusium, Egypt
Suicide of Mark Antony
With Alexandria lost and believing Cleopatra dead, Antony falls on his sword. His death marks the end of organized resistance to Octavian.
Location: Alexandria, Egypt
Suicide of Cleopatra
Cleopatra, facing capture and humiliation, takes her own life—according to legend, by the bite of an asp. Her death ends the Ptolemaic dynasty.
Location: Alexandria, Egypt
Execution of Caesarion
Octavian orders the execution of Caesarion, Cleopatra’s son by Julius Caesar, to eliminate any rival claimants to Rome. The child’s death is a calculated act of political ruthlessness.
Location: Alexandria, Egypt
Blockade of Actium Begins
Agrippa’s fleet establishes a tight blockade around Antony and Cleopatra’s forces at Actium, trapping them in the bay and beginning the slow process of starvation and attrition.
Location: Actium, Greece
Failed Breakout Attempt
Antony attempts to break the blockade with a dawn naval assault. Initial success is overwhelmed by Agrippa’s counterattack, resulting in heavy losses and further demoralization of Antony’s fleet.
Location: Ambracian Gulf, Greece
Battle of Actium
The climactic naval battle sees Octavian’s forces, under Agrippa, decisively defeat Antony and Cleopatra’s combined fleet. Cleopatra flees the battle, followed by Antony, leaving their armies to collapse.
Location: Actium, Greece
Massacre at Actium Camp
Octavian’s troops overrun Antony’s camp, slaughtering hundreds of prisoners and wounded soldiers. The brutality cements Octavian’s victory but leaves a legacy of resentment.
Location: Actium, Greece
Octavian Seizes Antony’s Will
Octavian’s agents acquire Antony’s will from the Vestal Virgins in Rome, revealing Antony’s plans to be buried in Egypt and distribute lands to Cleopatra’s children. The scandal fuels Octavian’s propaganda and turns public opinion against Antony.
Location: Rome, Italy
Senate Declares War on Cleopatra
At Octavian’s urging, the Roman Senate formally declares war—not on Antony, but on Cleopatra. This reframing galvanizes support for Octavian and isolates Antony as a traitor allied with a foreign queen.
Location: Rome, Italy
Agrippa Captures Methone
Agrippa leads a surprise assault on the Greek port of Methone, capturing the city and cutting off Antony’s supply lines. The sack is brutal, with many civilians killed or sold into slavery.
Location: Methone, Greece
