Concordia was the Roman goddess of harmony, agreement, and social unity. Her name came directly from the Latin con (together) and cor (heart) — literally, hearts joined together — and she embodied the principle that Roman civilization depended on for its existence: the willingness of groups with competing interests to find workable agreement rather than destroy each other.
She was a personification rather than a deity with ancient mythological roots, but personifications in Roman religion were not decorative abstractions. They were theological arguments made visible in stone, on coins, and in the ritual calendar. Concordia’s argument was one Rome needed to make to itself repeatedly, because the alternative — discordia, discord — was the condition Rome had experienced during its most catastrophic periods. Every temple built to Concordia was built in the shadow of a conflict that had recently ended, or that someone desperately wanted to end.
The First Temple and the Class Struggle
Concordia’s earliest cult in Rome was connected directly to one of the most consequential social conflicts in Roman history: the Conflict of the Orders, the centuries-long struggle between the patrician aristocracy and the plebeian majority over political rights, access to magistracies, and the distribution of conquered land.
The traditional account, given by Livy and others, held that the first temple of Concordia was built on the Capitoline Hill in 367 BCE following the passage of the Licinian-Sextian laws, which opened the consulship to plebeians for the first time. The laws were the product of a decade of intense political conflict, including plebeian strikes — the withdrawal of the plebs from the city and its army — that had brought Rome’s civic and military functioning to a halt. The dedication of a temple to Concordia at the moment of settlement expressed the institutional acknowledgment that the agreement reached was a genuine reconciliation rather than a temporary ceasefire.
Whether this temple was actually built in 367 BCE or whether the tradition was a later reconstruction is debated among ancient historians. What is clear is that by the late Republic the association between Concordia and the resolution of the class conflict was firmly established. The goddess of harmony was understood to have been present at Rome’s most important domestic political turning point.
The Temple of Concord in the Forum
The most physically significant monument to Concordia was her temple at the western end of the Roman Forum, at the foot of the Capitoline Hill — one of Rome’s most prominent locations, visible from the Forum’s center and positioned between the civic and religious heart of the city.
The temple’s history was a compressed version of Roman political history itself. It was reportedly first dedicated in 121 BCE by the consul Lucius Opimius following the death of Gaius Gracchus — the populist tribune whose reform program had split Roman politics and whose killing, along with thousands of his supporters, had been authorized by the Senate under Opimius’s direction. The dedication of a temple to Concordia in the immediate aftermath of this political massacre was not subtle: it was Opimius declaring the conflict over on his terms and using the goddess of harmony to ratify a victory that much of Rome regarded as a crime.
The temple was rebuilt and substantially expanded under Tiberius, who dedicated the rebuilt version in 10 CE and named it in honor of his brother Drusus, who had died in Germany in 9 BCE. The dedication connected Concordia specifically to dynastic harmony — the unity of the imperial family — and the rebuilt temple functioned as much as a memorial to Drusus as a religious monument. Its artistic program was elaborate: Tiberius filled it with Greek sculptures and artworks that made it one of the most significant art collections in Rome.
The Senate used the Temple of Concordia for its meetings on numerous occasions, which gave the goddess of harmony a practical administrative function. Important debates, crisis sessions, and the trials of political prisoners were conducted in her precinct. The most famous of these was Cicero’s delivery of the third Catilinarian oration in the temple in 63 BCE, during which he announced the execution of Catiline’s co-conspirators — another instance of Concordia’s association with the suppression of domestic conflict by any means necessary.
Concordia and the End of Civil War
The most politically significant deployments of Concordia as a divine symbol came during and after Rome’s catastrophic civil wars of the late Republic.
Julius Caesar used Concordia imagery on his coins and in his rhetoric of clementia — clemency toward defeated enemies — as part of his attempt to present the civil war’s conclusion as national reconciliation rather than personal victory. The attempt failed to convince his assassins, who were waiting with daggers.
Augustus was considerably more successful. After the defeat of Antony and Cleopatra in 31 BCE, the end of the civil wars, and his consolidation of power, Augustus deployed Concordia extensively as one of the theological pillars of his new order. Concordia on Augustan coins expressed the peace between the competing forces that had nearly destroyed Rome — the harmony that Augustus had achieved, or imposed, depending on one’s perspective. The Ara Pacis Augustae — the Altar of Augustan Peace — was conceptually connected to Concordia: both expressed the claim that the wars were genuinely over and that the new political settlement was divinely sanctioned.
The Concordia Augusta — Concordia of the Augustan house, Concordia of the emperors — emerged as a specific variant of the goddess’s cult during the imperial period. Where the Republican Concordia had governed political harmony between Rome’s classes and factions, Concordia Augusta governed the unity of the imperial family, whose internal cohesion was understood as the foundation of the empire’s stability. Empresses used Concordia Augusta imagery particularly prominently, because the demonstration of marital harmony — concordia between emperor and empress — was a political statement about dynastic continuity and the security of succession.
Livia, Augustus’s wife, promoted Concordia Augusta as part of her carefully managed public image. Later empresses including Sabina (wife of Hadrian) and Faustina the Elder and Younger (wives of Antoninus Pius and Marcus Aurelius respectively) appeared on coins with Concordia Augusta imagery, their faces paired with the goddess who embodied marital and dynastic harmony. The theological argument was clear: the imperial family’s internal unity was a model for the empire’s, and the goddess of harmony guaranteed both.
Concordia’s Symbols
Concordia was depicted consistently across coins, sculpture, and architectural decoration with a specific set of attributes that expressed her domain precisely.
The patera — the shallow offering dish used in sacrifice — expressed her role in the ritual acts that bound communities together. Roman sacrifice was not simply a religious act but a civic one: the shared sacrifice performed in Concordia’s name was the physical enactment of the unity she embodied. Communities that sacrificed together were communities that agreed to be communities.
The cornucopia expressed the abundance that harmony made possible. Discord was economically destructive — civil wars disrupted agriculture, trade, and production. Concordia’s cornucopia was not simply a decorative symbol of plenty but a theological claim: harmony was the precondition for prosperity, and her worship was the precondition for Rome’s material wellbeing as much as its civic health.
The caduceus — Mercury’s herald’s staff, the symbol of peaceful negotiation and protected communication — appeared with Concordia as an expression of the means by which harmony was achieved: through speech, negotiation, and the protection of the messenger who carried terms between opposing parties.
Clasped hands — the dextrarum iunctio — were perhaps her most powerful symbol, appearing on coins and in her cult imagery from the Republic through the Empire. The handshake expressed agreement, treaty, and the physical joining of what had been separated. It was the gesture made at the conclusion of negotiations, at the solemnization of marriages, at the settlement of disputes. Concordia made that gesture divine.
Concordia and Marriage
Concordia’s domain extended from the civic to the domestic. Roman marriage was not understood simply as a personal arrangement but as an institution whose stability was directly relevant to the health of the state. Families that were internally harmonious produced citizens capable of participating in civic harmony. The marital concordia between husband and wife was continuous with the political concordia between Rome’s social groups.
Wedding ceremonies invoked Concordia. Domestic shrines incorporated her imagery. The ideal Roman marriage was described in terms of concordia — mutual agreement, shared purpose, the joining of hearts expressed in her name. When Pliny the Younger wrote to his wife Calpurnia during his absence from Rome, the quality he praised most consistently was their concordia — the harmony of their minds and tastes and lives.
The Concordia Augusta of the imperial household extended this domestic concept to the highest political level: the emperor and empress in harmonious marriage were Rome in microcosm, their unity the theological expression of the empire’s unity, their concordia the model and the guarantee of the concordia of the whole.
The Word’s Survival
Concordia’s name survived the goddess in every language descended from Latin. The English word “concord” — agreement, harmony — is Concordia’s name reduced to its concept, stripped of its divine personhood but retaining its meaning. The French concorde, the Italian concordia, the Spanish concordia: all preserve her intact in her abstract form.
The Concorde supersonic aircraft was named for the French-British agreement that produced it. The Plaza de la Concorde in Paris — renamed from the Place de la Révolution, where the guillotine had stood — expressed the post-revolutionary aspiration for national unity through the Latin goddess’s Gallic name. The Treaty of Concordia of 1648 (part of the Peace of Westphalia) used her name to designate international agreement.
These uses expressed the same Roman understanding Concordia had always embodied: that harmony was not a natural state but an achievement, requiring effort and will and sometimes divine assistance, and deserving formal acknowledgment when it was reached.
Concordia’s Place in Roman Religion
Concordia occupied an unusual theological position — she was simultaneously one of Rome’s most politically instrumental divine symbols and one of its most genuinely needed ones. The irony that her temples were built most prominently at moments of intense discord was not lost on Romans, and some ancient writers commented on it. Plutarch noted that Opimius’s dedication of a temple to Concordia after the killing of Gaius Gracchus and his supporters was widely considered a provocation rather than a reconciliation — the goddess of harmony invoked by the man who had just authorized mass political murder.
But this irony expressed something true about Concordia’s function. She was not the goddess of harmony already achieved. She was the goddess of harmony aspired to, sought, and occasionally forced. Her cult was most active at the moments when her domain was most absent, because those were the moments when Rome most needed the divine ratification of whatever settlement had been or needed to be reached.
In this sense she was one of Rome’s most honestly pragmatic divine figures. She did not govern a natural phenomenon like the sea or the harvest. She governed a social achievement — the condition of people agreeing with each other — that was fragile, contested, and in constant need of maintenance. Her temples were the institutional acknowledgment of that fragility, her cult the ritual practice of the aspiration to do better.
Final Take: Concordia
Concordia mattered because agreement is harder than conflict, and Rome knew it. The civil wars of the late Republic — Romans killing Romans in numbers that dwarfed most foreign wars — were the demonstration of what happened when concordia failed at the highest level. The class struggles of the early Republic were the demonstration of what happened when it failed at the structural level. The domestic discords that Roman moralists warned against were the demonstration of what happened when it failed at the smallest level.
She was invoked at every scale simultaneously, from the marriage bed to the Senate floor to the conquered territories that Rome needed to keep pacified and integrated. The clasped hands on her coins were not naive. They were aspirational, which is a different thing — the acknowledgment that harmony was possible and worth the effort, even when the evidence suggested otherwise.
Every temple built to her in the aftermath of conflict was Rome admitting that it had failed and trying again. That willingness to try again, consecrated in stone and ritual, was itself a form of concordia.
