What this dot point is asking
NESA expects you to explain the trajectory of the Second Triumvirate from its legal formation in November 43 BC, through the proscriptions and Philippi (42 BC), the recurring strains in the three-way partnership (Perusia, Brundisium, Misenum, Naulochus, Lepidus's fall), Antony's Eastern policy and alliance with Cleopatra, the propaganda war, and the Battle of Actium (31 BC), ending with the consequent emergence of Octavian as sole master of the Roman world in 30 BC.
The answer
The formation of the Second Triumvirate (November 43 BC)
After Julius Caesar's assassination (44 BC) and Octavian's break with the Senate over Mutina, Octavian, Antony and Lepidus met near Bononia in October 43 BC and agreed a formal, legal alliance. The tribune Publius Titius carried the lex Titia through the popular assembly on 27 November 43 BC, creating the office of tresviri rei publicae constituendae ("triumvirs for the reorganisation of the state") for a five-year term, with consular imperium and the power to legislate and to nominate magistrates without the Senate's consent.
The proscriptions (43-42 BC)
Within days of taking office, the triumvirs published proscription lists naming political and personal enemies as outlaws, subject to execution and confiscation of property, consciously echoing Sulla's proscriptions of 82 BC. In the ancient tradition (chiefly Appian, Civil Wars 4.5), around 300 senators and 2,000 equites were proscribed - figures modern historians treat with caution, since ancient sources routinely inflate victim counts for rhetorical effect and no contemporary tally survives.
The most prominent victim was Cicero, killed in December 43 BC on Antony's initiative after his Philippics had attacked Antony as a tyrant; his head and hands were displayed on the Rostra. The proscriptions served two purposes at once: eliminating opponents and raising the enormous cash needed to pay the armies the triumvirs were about to march against Brutus and Cassius.
The Triumvirate's first achievement: Philippi (42 BC)
The Liberators Brutus and Cassius had raised armies in the East after Caesar's assassination. Their forces met those of Antony and Octavian at Philippi in Macedonia in October 42 BC.
Two battles were fought. In the first, Brutus defeated Octavian's wing while Antony defeated Cassius's wing; Cassius committed suicide. In the second battle three weeks later, Antony and Octavian defeated Brutus, who committed suicide.
Philippi destroyed the Republican opposition. The Triumvirate now controlled the Roman world.
Division of the Empire and its strains (42-36 BC)
After Philippi the Triumvirate divided the empire. Octavian took Italy and the West (Spain, Gaul). Antony took the East (Greece, Asia Minor, Syria, Egypt's region of influence). Lepidus took Africa. The arrangement was unstable from the start.
- The Perusine War (41-40 BC)
- Antony's wife Fulvia and his brother Lucius Antonius resisted Octavian's programme of settling discharged veterans on confiscated Italian land, raising an army and holding the town of Perusia (modern Perugia). Octavian besieged and starved the town into surrender in early 40 BC; Fulvia fled to Greece and died soon after, and Lucius was pardoned. The episode brought Octavian and Antony to the brink of open war.
- The Treaty of Brundisium (40 BC)
- With Fulvia dead, Octavian and Antony met at Brundisium and restored the alliance, confirming the division of the empire (Octavian the West, Antony the East, Lepidus Africa) and sealing it with Antony's marriage to Octavia, Octavian's sister. Octavia bore Antony two daughters.
- The Pact of Misenum (39 BC)
- Sextus Pompeius, son of Pompey the Great, controlled Sicily, Sardinia and Corsica with a powerful fleet and was strangling Italy's grain supply. At Misenum the triumvirs recognised his hold on those provinces in exchange for lifting the blockade - a temporary, uneasy truce.
- Naulochus (36 BC)
- War with Sextus resumed; Agrippa, commanding Octavian's rebuilt fleet, decisively defeated Sextus off Naulochus (Sicily) in September 36 BC. Sextus fled east and was later killed.
- Lepidus sidelined (36 BC)
- In the aftermath of Naulochus, Lepidus attempted to claim Sicily for himself and assert equal standing, but his legions deserted to Octavian. Octavian stripped him of triumviral power, sparing his life but confining him to the ceremonial office of Pontifex Maximus for the rest of his life. The Triumvirate was now, in practice, a duumvirate of Octavian and Antony.
Antony in the East
Antony based himself in the East, first in Athens with Octavia and then increasingly in Alexandria with Cleopatra VII, whom he had first met in 41 BC.
The Parthian campaign (36 BC) was a disaster. Antony lost around 22,000 men in the Mesopotamian withdrawal. The setback weakened his prestige and pushed him closer to relying on Cleopatra's resources for a renewed Eastern campaign.
Antony and Cleopatra had three children: Alexander Helios (named for Alexander the Great, sun god), Cleopatra Selene (moon goddess), and Ptolemy Philadelphus.
The Donations of Alexandria (34 BC)
In a public ceremony at the Gymnasium of Alexandria, Antony conferred royal titles on Cleopatra and her children.
Caesarion (Cleopatra's son by Julius Caesar) was named "King of Kings"; Cleopatra was named "Queen of Kings." Alexander Helios was named king of Armenia and ruler of regions east of the Euphrates. Cleopatra Selene was named queen of Cyrenaica and Libya. Ptolemy Philadelphus (then two) was named king of Phoenicia, Syria, and Cilicia.
The Donations transferred Roman provincial territories to a foreign queen and her children, by the authority of a Roman triumvir. Whether this was a serious political programme or Hellenistic royal theatre is debated. In Rome it was incendiary.
The propaganda war
From 33 to 32 BC, Octavian and Antony fought for Roman public opinion.
- Octavian's case
- Antony was the servant of an Eastern queen, betraying Roman virtue. Antony had abandoned the lawful wife Octavia for the foreign sorceress Cleopatra. The Donations were the giveaway of Roman territory. Antony's behaviour threatened the Roman state itself.
- Antony's case
- Octavian was a usurper, an enemy of his fellow triumvir, and the violator of triumviral agreements. Octavian's adoption was suspect; his power rested on military force alone.
- Antony's will
- Octavian claimed to have seized Antony's will from the Vestal Virgins and published its contents. The will allegedly confirmed Antony's identification with Cleopatra: he asked to be buried in Alexandria. The publication, though probably partly fabricated, completed Antony's political destruction in Rome.
The declaration of war (32 BC)
The Triumvirate had legally expired on 31 December 33 BC. Octavian and Antony's consulships continued the impasse.
In 32 BC Octavian, having secured an oath of allegiance from Italy and the western provinces, the coniuratio totius Italiae, declared war on Cleopatra. Augustus himself later recorded this oath as proof of universal consent in the Res Gestae (chapter 25: "the whole of Italy of its own free will swore allegiance to me"). The declaration framed the war as one against a foreign queen, not as a civil war against Antony. The traditional fetial ceremony at the Temple of Bellona was used.
Antony and Cleopatra spent the winter of 32 to 31 BC at Patrae and Athens preparing the campaign.
The Battle of Actium (2 September 31 BC)
The decisive engagement took place at the entrance to the Ambracian Gulf, off the western coast of Greece.
- Forces
- Octavian's fleet under Marcus Vipsanius Agrippa consisted of around 250 lighter Liburnian ships. Antony commanded around 230 heavier quinqueremes. Cleopatra's Egyptian squadron of around 60 ships, including the treasure transports, was behind Antony's line.
- Pre-battle situation
- Agrippa had blockaded Antony's fleet and army on land for months. Antony's troops were suffering from disease and desertion. Antony's strategy was either to defeat Octavian in a decisive battle or to break out to Egypt with the fleet.
- The battle
- On 2 September 31 BC, Antony's fleet sailed out to engage. After several hours of indecisive fighting, Cleopatra's Egyptian squadron raised sail and broke through the centre carrying the treasure. Antony followed in a smaller vessel. The remaining fleet, abandoned by its commanders, surrendered. Antony's land army on the Greek shore surrendered days later.
Alexandria and the aftermath (30 BC)
Octavian pursued Antony and Cleopatra to Egypt. In August 30 BC Antony, hearing false reports of Cleopatra's death, fell on his sword. Cleopatra, after attempting to negotiate with Octavian, committed suicide (traditionally by asp; the historicity of the method is debated).
Caesarion, Cleopatra's son by Julius Caesar (now seventeen), was killed on Octavian's orders ("Two Caesars are too many"). Egypt was annexed as a Roman province under the direct administration of the emperor's personal prefect; senators were forbidden to enter Egypt without imperial permission - a measure that shows how strategically and symbolically important the province had become.

Historiography
Adrian Goldsworthy (Augustus: First Emperor of Rome, 2014) treats Actium as the decisive military victory but emphasises the political and propaganda preparation, and cautions against reading it as a foregone conclusion.
Mary Beard (SPQR, 2015) reads the Donations as legitimate Hellenistic dynastic politics that Octavian successfully framed as Eastern decadence.
Ronald Syme (The Roman Revolution, 1939) treats Actium as a propaganda victory: the political destruction of Antony in Rome had been accomplished before the naval engagement.
How to read a source on this topic
Section IV sources typically include extracts from Augustus's Res Gestae, Suetonius, Plutarch's Life of Antony, Cassius Dio, Appian, or images on Triumvirate-era and Actium coinage. Four reading habits.
First, watch for the post-victory frame. Augustus's Res Gestae presents Actium as a war "against external enemies"; in fact it was a civil war framed as foreign war. Note the framing.
Second, distinguish propaganda from event. The Donations were real, but Octavian's interpretation of them is propaganda. Use both as evidence at different levels.
Third, identify the source's affiliation. Augustan-era sources (Virgil, Horace, Res Gestae) are pro-Octavian. Later sources (Plutarch, Dio, Appian) are more balanced but still write with hindsight and moralising purpose.
Fourth, treat casualty and victim figures (proscription numbers, army sizes) as tradition, not certainty, and say so explicitly when using them.

Show worked solution →
1 mark - names the lex Titia (proposed by the tribune Publius Titius, passed by the popular assembly, 27 November 43 BC), which gave Octavian, Antony and Lepidus the formal joint office of tresviri rei publicae constituendae ("triumvirs for the reorganisation of the state") for five years, with consular power (imperium) and the authority to legislate without senatorial approval.
1 mark - identifies that this made the Triumvirate legal, unlike Caesar's earlier informal First Triumvirate: it was a constitutional magistracy, not a private pact.
1 mark - describes the proscriptions that followed within days: the three men published lists condemning their political enemies (and, in several cases, personal enemies or wealthy men whose property they wanted) to death and confiscation, in the tradition of Sulla's proscriptions of 82 BC.
1 mark - names the death of Cicero (December 43 BC), the most prominent victim, killed on Antony's initiative after the Philippics.
Markers reward the correct name and date of the law, its constitutional character, and at least one specific consequence with a date/name.

1 mark - defines proscription: a published list naming citizens as outlaws, whose property was confiscated and who could be killed with impunity and a reward paid to the killer.
1 mark - gives the scale in the ancient tradition: Appian (Civil Wars 4.5) and later tradition place the number at around 300 senators and 2,000 equites (knights) proscribed; modern historians flag these figures as probably exaggerated for effect and impossible to verify precisely.
1 mark - explains the political function: the proscriptions eliminated opponents (Cicero, killed December 43 BC, was the most famous victim after his Philippics against Antony) and, crucially, raised cash to pay the triumvirs' huge armies before Philippi.
1 mark - explains the significance for interpretation: the proscriptions show the Triumvirate operating as an extra-legal terror despite its legal form, and set a precedent (echoing Sulla) that Octavian's own regime later worked hard to distance itself from in its propaganda.
Markers reward the ancient figure (flagged as tradition, not certain fact), Cicero by name, and the dual purpose (revenge and finance).

Show worked solution →
1-2 marks (identify/describe) - the coin pairs Octavian's and Antony's portraits and carries the triumviral title, presenting the two as equal, legitimate joint rulers; the reverse links both to the deified Caesar, from whom Octavian's authority derived (as adopted heir) and whom Antony had avenged.
2-3 marks (explain using own knowledge) - this matches the real political situation in 42 BC: the Triumvirate was freshly confirmed by the lex Titia, and Philippi (October 42 BC) was fought jointly, with Antony as the dominant military partner. Coinage of this type was a deliberate propaganda tool circulated to soldiers and the public to project triumviral unity ahead of and during the Philippi campaign.
1-2 marks (assess usefulness) - as archaeological/numismatic evidence, coinage is useful because it is official, contemporary and reaches a mass audience, but it is also propaganda: it shows the desired image of unity, not the real tensions (already visible in the unequal division of resources) that would surface within two years at Perusia and Brundisium. A student should note that coin evidence needs to be read alongside written sources (Appian, Cassius Dio) for the political narrative behind the image.
Markers reward correct decoding of the coin's message, a precise link to 42 BC events, and an explicit reliability/usefulness judgement (not just description).

exam20 marksTo what extent was the propaganda war of 33 to 32 BC, rather than the Battle of Actium itself, the decisive factor in Octavian's victory over Antony and Cleopatra?
Show worked solution →
Band 6 thesis: Octavian's victory was decided chiefly in the propaganda war of 33-32 BC, which destroyed Antony's political standing in Rome and secured Octavian an army and a mandate before a shot was fired at Actium; the battle itself confirmed a victory that was, as Ronald Syme argued, substantially already won.
Argument line 1 - the propaganda campaign dismantled Antony politically. Octavian publicised the Donations of Alexandria (34 BC), in which Antony had granted Roman-claimed Eastern territories to Cleopatra and her children (Caesarion named "King of Kings"; Alexander Helios, Cleopatra Selene and Ptolemy Philadelphus each granted kingdoms), presenting this as the give-away of Roman territory to a foreign queen. Octavian then seized and published Antony's will from the Vestal Virgins in 32 BC, alleging Antony wished to be buried beside Cleopatra in Alexandria - whether or not authentic in full, its publication was politically ruinous and swayed Roman opinion decisively against Antony.
Argument line 2 - the oath of Italy created Octavian's legal and military mandate. In 32 BC Octavian secured a coniuratio totius Italiae, an oath of personal allegiance sworn by Italy and the western provinces (recorded by Octavian himself in the Res Gestae 25 as evidence of universal consent). This let Octavian declare war formally on Cleopatra alone through the fetial ritual, framing the coming conflict as a foreign war for national survival rather than another round of civil war between Roman citizens, and gave him troops and funding without needing Senate unanimity.
- Argument line 3 - Actium confirmed rather than created the victory
- By September 31 BC, Antony's forces at Actium were already weakened by disease and desertion after Agrippa's months-long blockade; the battle on 2 September 31 BC was, in Syme's phrase, an anticlimax after the political campaign - a breakout attempt in which Cleopatra's squadron fled with the treasure and Antony followed, after which the remaining fleet and the land army surrendered with little further fighting.
- Counter-argument (for a full-mark response)
- Goldsworthy cautions against reading Actium as a foregone conclusion - Octavian and Agrippa still had to translate political advantage into a functioning blockade and a competently fought naval campaign, and a military reverse in 31 BC could have unwound the propaganda gains. The extent question should therefore concede that Actium was necessary, even if the propaganda war made it likely to succeed.
- Model paragraph
- "The Donations of Alexandria and the publication of Antony's will did more to defeat Antony than any manoeuvre at Actium. By staging Antony as the tool of an Eastern queen giving away Roman provinces to her children, Octavian converted a personal rivalry between two triumvirs into a national emergency that only he could resolve. The coniuratio totius Italiae he records in the Res Gestae was the direct product of this campaign, delivering him the men and money to fight before Antony had time to answer the charge in Rome. Agrippa's blockade at Actium then exploited an army already rotted by disease and desertion, so that the battle itself, as Syme argues, merely confirmed a verdict reached in the court of Roman opinion the previous year."
- Marker's note
- full marks require dated evidence for the Donations, the will, the oath and Actium, an explicit "to what extent" judgement (not just narrative), and engagement with named historians (Syme's propaganda-victory reading against Goldsworthy's caution) rather than a single-source answer.
exam25 marksESSAY. Assess the role of the proscriptions and the Battle of Philippi in establishing the power of the Second Triumvirate.Show worked solution →
A Band 6 essay assesses the two instruments together, distinguishing what each achieved for the triumvirs, and reaches a weighted verdict. Plan plus model paragraph.
- Thesis
- The proscriptions and Philippi were complementary instruments of consolidation: the proscriptions secured the triumvirs' rear (money, terror, the elimination of the senatorial opposition at Rome), while Philippi destroyed the republican cause in the field. Philippi was the more decisive because it removed the only army that could have reversed the lex Titia, but without the proscriptions the campaign could not have been financed or safely fought.
- Line 1: the proscriptions as political surgery
- From late 43 BC the triumvirs posted lists condemning their enemies: the tradition (Appian, Civil Wars 4.5) puts the toll at around 300 senators and 2,000 equites, figures to be treated as ancient tradition rather than audited fact. The deaths (Cicero above all, killed 7 December 43 BC) decapitated the republican leadership in Italy and advertised that the amnesty politics of 44 BC were over.
- Line 2: the proscriptions as war finance
- Confiscated estates were auctioned to pay the enormous armies (over 40 legions between the parties by 42 BC). The measure worked poorly as revenue (frightened markets, depressed prices), which is itself evidence the primary motive mixed finance with terror and vengeance for Caesar.
- Line 3: Philippi as the military decision
- In October 42 BC the two battles at Philippi in Macedonia ended with the suicides of Cassius and then Brutus. The republican field army dissolved, and with it any prospect of restoring the pre-Caesarian order; the surviving opposition was reduced to Sextus Pompeius's fleet. Antony took the victor's prestige, a fact that shaped the next decade's balance between the triumvirs.
- Line 4: qualification and aftermath
- Consolidation was not completion: Perusia (41-40 BC), Sextus Pompeius, and the triumvirs' own rivalry showed that the settlement created by terror and victory remained unstable, because it had removed the republic without deciding which dynast would replace it.
- Model paragraph (line 3)
- Philippi mattered more than any list posted in the Forum because armies, not edicts, decided the age. So long as Brutus and Cassius held the East with twenty legions and the treasuries of Asia, the lex Titia was a claim rather than a fact, and every proscribed name was an argument for their cause. The double battle of October 42 BC converted the triumvirate's legal fiction into a monopoly of force: after Cassius's premature suicide and Brutus's defeat, no republican army existed anywhere in the Roman world. What remained thereafter was not a struggle for the republic but a struggle for its inheritance, fought between the victors themselves.
- Conclusion
- Jointly decisive in sequence: the proscriptions made the war winnable and Rome obedient, Philippi made the triumvirate unchallengeable; a strong answer notes that the same instruments guaranteed the triumvirate would eventually devour itself.
Marker's note: "assess the role" requires each instrument's contribution weighed, with precise dated evidence (lex Titia November 43 BC, Cicero's death, Philippi October 42 BC, the Appian figures flagged as tradition) and the aftermath acknowledged. A narrative of the proscription horrors without an argued verdict caps the response at mid-band.
