The Second Triumvirate: An Overview
A Formal Commission
The Second Triumvirate was an extraordinary commission and magistracy formally constituted by law on November 27, 43 BC. It granted Mark Antony, Lepidus, and Octavian sweeping, near-absolute powers for a statutory term of five years, later renewed. This legal framework, established by the lex Titia, empowered the triumvirs to legislate, impose judicial punishments without due process or appeal, and appoint magistrates, effectively superseding traditional republican structures.
Post-Caesarian Power Struggle
Emerging from the conflict between Antony and the Senate following Julius Caesar's assassination, the Triumvirate was initially formed to consolidate Caesarian control over the western provinces and to confront the assassins (the liberatores). Their consolidation of power involved brutal proscriptions and a devastating civil war, ultimately leading to the defeat of Caesar's killers.
Division of the Roman World
Following their initial victories, the triumvirs divided the Roman territories amongst themselves. Antony assumed control of the East, Octavian the West, and Lepidus was relegated to Africa. This division, however, was fraught with tension and competition, particularly between Antony and Octavian, which would ultimately lead to the Triumvirate's dissolution and the rise of Octavian.
The Name: A Modern Convention
Historical Nomenclature
The term "Second Triumvirate" is a modern designation, not used during the period itself. It emerged during the Renaissance and gained widespread acceptance in the 18th century, drawing a parallel to the earlier political alliance of Pompey, Crassus, and Caesar. Contemporary scholars increasingly question this traditional nomenclature, noting its anachronistic nature and potential to mislead regarding the distinct legal and political character of these alliances.
Scholarly Debate
Leading classical dictionaries and academic works now caution against the use of "First" and "Second" Triumvirate, highlighting that the terms were unknown to contemporaries. This academic shift reflects a deeper understanding of the evolving political landscape and the specific legal frameworks under which these powerful figures operated.
The Triumviral Period: A Crucible of Change
Foundation and Renewal
Established on November 27, 43 BC, the Second Triumvirate was legally sanctioned for an initial five-year term. This mandate was subsequently renewed in 37 BC for another five years, extending its official duration until 32 BC. However, the practical political dominance of the triumvirs, particularly the shifting alliances and conflicts between Antony and Octavian, extended beyond these formal terms, culminating in Octavian's sole rule.
Seeds of Conflict
The period was marked by intense political maneuvering, civil strife, and military campaigns. The initial unity forged against Caesar's assassins gradually eroded, replaced by personal ambition and strategic divergence between Antony and Octavian. This internal friction, coupled with external challenges like Sextus Pompey's naval power, defined the era and ultimately led to the Republic's final collapse.
The Genesis of Power: 43 BC
Post-Assassination Settlement
In the immediate aftermath of Caesar's assassination in March 44 BC, a fragile settlement was reached between the assassins and Caesar's supporters. This included an amnesty for the killers and confirmation of Caesar's legislative acts. However, this accord quickly disintegrated as Mark Antony secured key provinces and Octavian, Caesar's heir, began consolidating his own power base, forming a private army.
The Pact of Triumvirs
By August 43 BC, Octavian, having secured the consulship, reconciled with Antony and Lepidus. Under pressure from their legions, they met and established the triumviri rei publicae constituendae (Triumvirs for the reconstitution of the Republic). This arrangement was formalized by the lex Titia, granting them unprecedented powers, including the ability to issue edicts, act without right of appeal, and appoint magistrates, effectively establishing a legal dictatorship.
Legal Authority and Provincial Division
The lex Titia mirrored earlier legislation that established Sulla's dictatorship, granting the triumvirs supreme authority. They received imperium maius, allowing them to override provincial governors, and powers to convene the Senate and directly appoint officials. The Roman world was then divided: Antony received Cisalpine and Transalpine Gaul, Lepidus gained Narbonensis and Spain, and Octavian took Africa, Sardinia, and Sicily.
The Proscriptions: Purging the Republic
Financial Necessity and Political Elimination
Facing severe financial shortages, the triumvirs initiated a brutal policy of proscriptions, essentially creating death lists. This measure, justified by Appian as a response to Caesar's perceived failure of clemency, targeted senators and equestrians. Approximately three hundred senators and two thousand equestrians were killed, their properties confiscated and sold to fund the triumvirs' military campaigns.
Personal and Political Retribution
The proscriptions were not merely political purges but also instruments of personal retribution. Prominent figures like Cicero, who had actively opposed Antony, were targeted. The triumvirs themselves traded allies and family members to add enemies to the lists, demonstrating the ruthless nature of their consolidation of power. Informers and bounty hunters were rewarded for aiding in the killings.
Impact on Italian Lands
Beyond the human cost, the triumvirs seized eighteen wealthy Italian towns, redistributing their lands to their soldiers. This action, driven by the need to reward veterans and secure loyalty, caused widespread unrest and displacement throughout Italy, further destabilizing the already fractured Republic.
The Liberators' War: Philippi and its Aftermath
Confronting the Assassins
The primary military objective of the triumvirs was to defeat the forces of Marcus Junius Brutus and Gaius Cassius Longinus, the leading assassins of Caesar. After consolidating their power in Italy and conducting the proscriptions, Antony and Octavian marshalled their legions for a campaign in the East.
The Battles of Philippi (42 BC)
The decisive confrontation occurred at the Battle of Philippi. In the initial engagement, Brutus achieved a victory against Octavian's forces, while Antony defeated Cassius. However, the subsequent suicide of Cassius, believing the battle lost, and a second battle three weeks later, resulted in the complete defeat of the liberators' army. Brutus also died by suicide, marking the end of organized senatorial opposition.
Reshaping the Triumvirate
The victory at Philippi significantly altered the triumvirs' internal dynamics. Antony, having played a more decisive role in the victory, gained considerable prestige. Lepidus' influence waned, and Octavian, despite his tactical setbacks, emerged as a key player. The triumvirs reorganized their provincial assignments, with Antony taking a larger share and Octavian focusing on the ongoing conflict with Sextus Pompey.
Antony's Eastern Ascendancy
Reorganization and Diplomacy
Following Philippi, Antony focused on reorganizing the wealthy eastern provinces. He displayed leniency towards regions previously supporting the liberators and engaged in diplomacy, notably with Cleopatra VII of Egypt. His relationship with Cleopatra deepened, securing her position on the throne and strengthening his own strategic alliances in the East.
The Parthian Campaign
Antony launched a major campaign against the Parthian Empire, seeking to avenge the Roman defeat at Carrhae. Despite initial successes by his lieutenant Publius Ventidius, Antony's own invasion in 36 BC faltered due to logistical issues and the betrayal of his Armenian allies. The campaign ended in a costly retreat, significantly damaging Antony's military reputation.
Political Maneuvers and Propaganda
Antony's actions, including his public identification with Dionysus and the "donations of Alexandria" where he crowned his children with Cleopatra as monarchs, were heavily criticized in Rome. Octavian skillfully used these events in a propaganda war, portraying Antony as corrupted by Eastern decadence and disloyal to Roman traditions.
Octavian's Western Consolidation
Campaign Against Sextus Pompey
While Antony campaigned in the East, Octavian faced the challenge of Sextus Pompey, who controlled Sicily and Corsica, disrupting vital grain supplies to Italy. After initial setbacks, Octavian, with significant naval preparations led by Marcus Vipsanius Agrippa, launched a decisive campaign. The naval victory at Naulochus in 36 BC effectively ended Sextus Pompey's threat.
Eliminating Lepidus
Following the victory over Sextus Pompey, Octavian moved against Lepidus, who had attempted to suborn Octavian's troops. Octavian skillfully secured the loyalty of the legions, leading to Lepidus's removal from the Triumvirate and his exile. This consolidated Octavian's control over Italy and the western provinces.
Propaganda and Political Acumen
Octavian proved adept at political maneuvering and propaganda. He exploited Antony's perceived transgressions, such as his relationship with Cleopatra and the donations of Alexandria, to portray himself as the defender of Roman values. His campaigns in Illyricum also provided him with military experience and resources, while his public works projects in Rome enhanced his popularity.
Navigating Alliances: Brundisium and Misenum
Treaty of Brundisium (40 BC)
Amidst deteriorating relations and the Perusine War, Antony and Octavian negotiated a peace treaty at Brundisium. This agreement reaffirmed their provincial divisions, with Antony confirmed in the East and Octavian in the West. The treaty was sealed by Antony's marriage to Octavian's sister, Octavia the Younger, intended to symbolize renewed unity, though underlying tensions persisted.
Pact of Misenum (39 BC)
Further negotiations led to the Pact of Misenum, an agreement with Sextus Pompey. He was granted control over Sicily, Sardinia, Corsica, and the Peloponnese for five years, in exchange for guaranteeing safe passage for Italian grain ships and suppressing piracy. This pact temporarily stabilized the Mediterranean but ultimately proved unsustainable.
Renewal of the Triumvirate (37 BC)
With the triumvirate's initial term expiring, Antony and Octavian met at Tarentum. Despite Antony's failed Parthian campaign and Octavian's struggles against Sextus Pompey, they agreed to renew the triumvirate for another five years. This renewal, though seemingly reinforcing their power, masked the growing chasm between them.
Antony's Parthian Folly
The Campaign's Objective
Driven by a desire to avenge the Roman defeat at Carrhae and reclaim the lost legionary standards, Antony launched a massive invasion of the Parthian Empire in 36 BC. He amassed sixteen legions and numerous auxiliary troops, aiming to conquer Parthia and secure Roman dominance in the East.
Strategic Miscalculations and Defeat
Antony's campaign was plagued by strategic errors. He advanced without adequate siege equipment, which was subsequently destroyed by the Parthians. The betrayal of his Armenian ally, Artavasdes II, and the swiftness of Parthian cavalry tactics proved insurmountable. The Roman army suffered heavy losses during a difficult retreat, losing approximately a third of its strength.
Impact on Antony's Prestige
The failure of the Parthian campaign was a significant blow to Antony's military prestige and political standing. It weakened his position relative to Octavian and fueled Octavian's propaganda efforts, portraying Antony as an incompetent leader influenced by foreign powers.
Octavian's Sicilian Victory
Agrippa's Preparations
To counter Sextus Pompey's naval blockade, Marcus Vipsanius Agrippa undertook extensive preparations, including the construction of the Portus Julius, a naval base designed for training and logistical support. These efforts were crucial for Octavian's eventual success against Sextus's fleet.
The Battle of Naulochus (36 BC)
In July 36 BC, Octavian and Lepidus launched a coordinated invasion of Sicily. Despite initial naval setbacks for Octavian, Agrippa secured a decisive victory against Sextus Pompey's fleet at the Battle of Naulochus on September 3. This victory effectively eliminated Sextus Pompey as a major threat to the triumvirs' power.
Lepidus's Downfall
Buoyed by the victory, Lepidus attempted to assert his own authority by challenging Octavian. However, Octavian swiftly neutralized Lepidus, securing the loyalty of his troops and forcing Lepidus into exile. This event left Octavian in sole command of Italy and the western provinces, further consolidating his power base.
The Unraveling: From Two to One
Propaganda War Intensifies
With Lepidus removed, the rivalry between Antony and Octavian escalated. Octavian launched a relentless propaganda campaign, highlighting Antony's relationship with Cleopatra and his perceived abandonment of Roman values. Antony, in turn, criticized Octavian's character and actions, but his responses lacked the same political impact in Rome.
Antony's Strategic Errors
Antony's decision to divorce Octavia and remain with Cleopatra, coupled with his controversial actions in the East, alienated Italian public opinion and provided Octavian with potent ammunition. Antony's failure to return crucial naval support to Octavian, as promised at Tarentum, further strained their relationship.
The Road to Actium
The triumvirate's legal term expired at the end of 33 BC, but the political reality was already shifting towards a final confrontation. Octavian, having secured his position and military strength, declared war on Cleopatra, effectively framing the conflict as a defense of Rome against foreign influence, thereby isolating Antony.
Enduring Legacy: Shaping the Principate
Foundation of the Principate
The Second Triumvirate, through its period of absolute rule and subsequent dissolution, directly paved the way for the establishment of the Principate under Augustus. The prolonged civil wars and the concentration of power in the hands of a single leader demonstrated the Republic's inability to function effectively, creating the conditions for a more centralized imperial system.
Transformation of Roman Governance
The triumvirs' exercise of power, though often presented with a veneer of republican legality, fundamentally altered Roman governance. Their ability to act sine provocatione (without right of appeal) and their control over appointments set precedents for imperial authority. The division of provinces and the management of military veterans also influenced Augustus' later administrative reforms.
Cultural Flourishing Amidst Chaos
Paradoxically, this period of intense political instability and violence also witnessed a flourishing of Roman literature and culture. The patronage of figures like Gaius Maecenas supported poets such as Horace and Virgil, whose works often reflected the anxieties and transformations of the era, providing invaluable insights into the social and political climate.
Key Milestones: A Chronology
Pivotal Events
The period from Caesar's assassination to Octavian's sole rule was tumultuous, marked by shifting alliances, civil wars, and constitutional upheaval. Key events include the formation of the Triumvirate, the proscriptions, the battles of Philippi, the division of provinces, the campaigns against Sextus Pompey and Parthia, and the final confrontation at Actium.
