Roman religion, priesthoods and state cult: WACE Year 12 Ancient History
“Roman religion, priesthoods and the state cult, and the use of religion to legitimise political authority in the late Republic”
Roman state religion was a public, ritual system aimed at keeping the gods favourable to Rome through correct observance, not personal faith. It was run by priestly colleges, above all the pontiffs (led by the pontifex maximus) and the augurs, whose members were the same senatorial aristocrats who governed Rome. Because magistrates needed favourable omens (auspicia) to act, control of religion was a direct instrument of political power, which leaders from the Gracchi to Caesar and Augustus exploited.
What this dot point is asking
SCSA wants you to understand Roman state religion as part of the machinery of power, not a separate spiritual sphere. In Rome religion and politics were fused: the same aristocrats who held magistracies also held priesthoods, and control of ritual, omen and the calendar was a real political weapon. You need to explain how the cult was organised, who controlled it, and how leaders used it to legitimise authority. The Rome option is examined through source analysis and essays, so you must name and evaluate evidence such as Cicero's De Natura Deorum and De Divinatione, Livy and the Res Gestae.
Roman religion was concerned above all with the correct performance of ritual to maintain the pax deorum, the right relationship between Rome and its gods. It was civic rather than personal: the goal was the safety and success of the state, secured by precise sacrifice, prayer and the observance of festivals. There was no separate priestly caste; instead the major priesthoods were held by leading senators alongside their political offices, so that the same men who commanded armies and proposed laws also interpreted the will of the gods.
The priesthoods were organised into colleges. The college of pontiffs supervised sacred law, the calendar, burials and the cults of the state, and was headed by the pontifex maximus, Rome's chief priest, who became one of the most prestigious positions in the state. The college of augurs interpreted the auspices, the signs by which the gods approved or vetoed public action, especially the flight of birds. There were also the quindecimviri who consulted the Sibylline Books in times of crisis, and the Vestal Virgins, who guarded the sacred fire of Vesta on which Rome's safety was believed to depend.
No major public act, election, assembly or battle could proceed without favourable auspices taken by a magistrate or augur. Because unfavourable signs could halt business, the power to observe the sky (obnuntiatio) became a tool to block political opponents. Religion was therefore not separate from politics; it was a lever within it.
The political uses of religion were everywhere. A magistrate who wished to obstruct a vote could declare that he was watching the heavens for omens, suspending public business. Priesthoods carried prestige that boosted a political career, and the office of pontifex maximus in particular conferred enormous standing. Julius Caesar understood this exactly: in 63 BC, while still relatively junior, he won election as pontifex maximus through lavish bribery, gaining a lifelong religious eminence that he used to underpin his political rise. As dictator he also reformed the calendar in 46 BC, producing the Julian calendar, an act that combined practical administration with the symbolic authority of ordering sacred time.
Cicero is our richest source for how the elite thought about religion, and a complex one. In works such as De Natura Deorum and De Divinatione he debates, often sceptically, whether divination really works, yet as an augur himself he defends the civic value of the traditional cult for social order. This tension is a gift for source analysis: it shows an educated Roman who may privately doubt the omens while publicly upholding a religion that bound the community and legitimated the governing class. Livy, writing under Augustus, by contrast presents religious observance as central to Rome's rise and religious neglect as a cause of disaster, a moralising perspective that must be weighed.
The pax deorum is the peace or favour of the gods, the harmonious relationship between Rome and its deities that correct ritual was meant to preserve. Romans believed that ritual error, neglected vows or ill omens broke this peace and brought disaster, so maintaining it through proper public worship was a duty of the state and a responsibility of its leaders.
Augustus made the political use of religion central to his settlement. He restored eighty-two temples, revived lapsed priesthoods and ancient rituals, and presented himself as the pious restorer of traditional religion after the impieties of civil war, claims he makes proudly in the Res Gestae. He took the title pontifex maximus in 12 BC on the death of Lepidus, uniting the supreme religious office with supreme political power, and after his death he was deified. The Ara Pacis Augustae and the Secular Games of 17 BC projected an ideology of restored piety and renewed favour from the gods, binding the new regime to Rome's oldest traditions.
This dot point matters because it shows that in Rome power and authority were sacralised. Legitimacy depended on being seen to maintain the favour of the gods, and the institutions of religion were controlled by the same aristocracy that ran the state. Understanding the priestly colleges, the auspices and the office of pontifex maximus lets you explain how leaders manufactured legitimacy, and how Augustus in particular used religious restoration to make his rule appear traditional and divinely sanctioned.
Move from the structure of the cult to its political exploitation.
Step 1: Define the civic religion
State that Roman religion aimed at the pax deorum through correct public ritual, not personal faith.
Step 2: Show who controlled it
Explain that the priestly colleges (pontiffs under the pontifex maximus, augurs) were held by the same senators who governed.
Step 3: The auspices as a lever
Explain that no public act could proceed without favourable auspices, so watching the sky (obnuntiatio) could block opponents.
Step 4: Examples of exploitation
Cite Caesar buying the pontificate in 63 BC and reforming the calendar in 46 BC, then Augustus restoring temples and taking pontifex maximus in 12 BC.
Step 5: Judge and evaluate sources
Conclude that religion sacralised and served power, and weigh Cicero's sceptical-yet-supportive stance and Livy's moralising.
Students often analyse Roman religion as if it were a matter of personal faith like a modern religion. Roman state cult was civic, ritual and political; what mattered was correct public performance and the favour of the gods toward the community. Strong answers focus on how priesthoods and omens functioned as instruments of authority rather than on private spirituality.

WACE 2021-style20 marksEvaluate the view that Roman state religion was primarily an instrument of political power in the late Republic.Show worked answer →
A 20 mark essay needs a thesis on religion as a political tool, then evidence.
Thesis. Argue that while religion aimed at the pax deorum, in practice it was controlled by, and served, the governing aristocracy.
The fusion of office and priesthood. Explain that senators held the priestly colleges, so the same men ran politics and ritual.
The auspices as a weapon. Show that magistrates could halt business by watching the sky (obnuntiatio), and that the pontificate boosted careers; Caesar won it in 63 BC by bribery.
Augustan use. Cite the restoration of temples and priesthoods and the title pontifex maximus in 12 BC, claimed in the Res Gestae.
Judgement. Conclude that religion sacralised authority and was a genuine lever of power, while conceding belief in the pax deorum was real. Markers reward the weighted judgement and Cicero.
WACE 2023-style8 marksAssess the usefulness of Cicero's writings on religion (De Natura Deorum, De Divinatione) as evidence for Roman attitudes to the state cult.Show worked answer →
An 8 mark source question needs origin, purpose and a usefulness judgement.
Origin and purpose. Philosophical works by Cicero, himself an augur, debating whether divination works while defending the civic value of traditional cult.
Usefulness. Very useful for elite attitudes, showing a man who may privately doubt omens yet publicly upholds religion for social order.
Limits. They reflect an educated sceptical elite, not popular belief, and are shaped by philosophical genre.
Judgement. Conclude they are highly useful for the political and civic function of religion among the elite provided this narrow perspective is acknowledged.
