What is the Senate?

A Shifting Balance of Power

The Senate of the Roman Empire, while a continuation of the venerable Roman Senate from the Republic, experienced a profound shift in its constitutional role. With the advent of the Empire under Augustus, the theoretical balance of power between the Senate and the Emperor was established as co-equal. However, in practical terms, the Emperor wielded absolute authority, rendering the Senate's actual power largely negligible.[1]

Prestige Over Authority

Despite its diminished practical authority, membership in the imperial Senate remained highly coveted. It served primarily as a symbol of immense prestige and elevated social standing within Roman society, rather than a direct avenue for political power.[1] This distinction highlights the evolving nature of Roman governance from a republican ideal to an imperial reality.

An Imperial Instrument

During the reigns of the early Emperors, significant legislative, judicial, and electoral powers were formally transferred from the traditional Roman assemblies to the Senate. Paradoxically, this transfer did not empower the Senate. Instead, due to the Emperor's absolute control, the Senate effectively became a mechanism through which the Emperor could legitimize and execute his autocratic policies and decisions.[1]

Membership & Procedure

Augustus' Reforms and Membership

Emperor Augustus inherited a Senate bloated to 900 members by Julius Caesar. Through three meticulous revisions, Augustus reduced its size to a more manageable 600, a number that largely remained consistent thereafter.[2] His reforms established strict criteria for senators:

  • Must be a citizen of free birth.
  • Must not have been convicted of crimes under lex Julia de vi private.
  • Must possess property worth at least 1,000,000 sesterces.[3]

Pathways to Senatorial Rank

Under the Empire, the primary route to senatorial status remained election to the quaestorship. However, only individuals already of senatorial rank—typically sons of senators—were eligible to stand for this election.[2] For those not born into the senatorial class, two imperial pathways existed:

  • The Emperor could grant permission to stand for quaestorship.[2]
  • The Emperor could directly appoint an individual to the Senate via a decree known as adlectio.[4]

The Album Senatorium and Rank

From 9 BC, Augustus' lex Julia de senatu habendo mandated an annual revision of the album senatorium, an official list of senators. This list detailed each senator by rank, with the Emperor always at the apex, followed by Consuls (and former Consuls), then Praetors (and former Praetors), and so forth.[4] A senator's tenure in elective office influenced their rank, though imperial appointments did not necessarily confer lower standing than elected positions.[4] Senators were visually distinguished by a broad reddish-purple stripe on their togas.

Meetings and Deliberations

Senate meetings typically convened in the Curia Julia, usually on the Kalends (first day) or Ides (around the fifteenth day) of the month, with more frequent sessions in September and October. Other meetings were held on an ad hoc basis.[4] Augustus initially set a quorum of 400 senators, though this was later reduced due to persistent absenteeism, and sometimes even revoked for certain matters.[5] The Emperor usually presided, sitting between the two Consuls, and could speak at any time, though higher-ranking senators generally spoke before lower-ranking ones.[5]

Most legislative proposals originated from the Emperor or his loyalists. Early emperors like Augustus and Tiberius subtly influenced the Senate through private lobbying rather than direct proposals.[3] Senators rarely voted against imperial bills, as their magisterial aspirations depended on the Emperor's approval. Disapproval was often expressed through absence from the voting session.[6]

The proceedings were meticulously recorded by a quaestor in the Acta Senatus, which included proposed bills, official documents, and summaries of speeches. Portions of this document were then published as the Acta Diurna ("daily doings") for public dissemination.[6]

Intriguingly, historical accounts suggest some women, like Emperor Elagabalus's mother or grandmother, participated in Senate proceedings, with Elagabalus even establishing a "women's senate" (senaculum) for matrons. Agrippina the Younger, Nero's mother, was known to listen to debates from behind a curtain.[1]

Imperial Powers

Legislative Authority

With the establishment of the Empire, the legislative powers previously held by the Roman assemblies were transferred to the Senate. Consequently, senatorial decrees (senatus consulta) gained the full force of law.[7] The Imperial Senate's legislative functions primarily encompassed financial and administrative matters, though it also retained some authority over provincial affairs.[7]

The Senate's legislative scope included:

  • Regulating festivals and religious cults.
  • Granting special honors.
  • Exempting individuals (often the Emperor) from legal liabilities.
  • Managing temples and public games.
  • Enacting tax laws, albeit always with the Emperor's ultimate approval.[7]

However, it held no genuine authority over the state religion or public lands, areas firmly under imperial control.

Judicial Functions

All judicial powers once held by the Roman assemblies were also transferred to the Senate during the early Empire. This included jurisdiction over criminal trials, where a consul presided, senators served as the jury, and the verdict was issued as a senatus consultum.[7][8] While these verdicts were not subject to appeal, the Emperor retained the power to pardon a convicted individual through his veto. Decisions from provincial courts under senatorial jurisdiction could also be appealed to the Senate, upon a consul's recommendation.[8]

Electoral Role

Theoretically, the Senate held the power to elect new emperors and, in conjunction with popular assemblies, confer upon them their command powers (imperium).[8] After an emperor's death or abdication, the Senate often deified him, or, in cases of severe disapproval, issued a damnatio memoriae ("damnation from memory") to erase all traces of his existence from Roman life.[8] Emperor Tiberius further consolidated electoral power by transferring all such functions from the assemblies to the Senate.[8] Despite the theoretical power of the Senate to elect magistrates, the Emperor's approval was always essential for an election to be finalized, yet elections remained fiercely contested.

Evolution & Decline

Periods of Renewed Influence

Under Emperor Vespasian (69-79 AD), senators experienced an increased role, serving as senior officials within the Imperial household in Rome or as provincial governors directly representing the Emperor. This expansion of responsibility offered greater opportunities for counsel and the exercise of authority.[9] A notable moment of senatorial agency occurred at the end of the Flavian dynasty when the Senate successfully chose Nerva as the new emperor, marking a rare instance of such initiative during the Empire.[9]

Following the death of Marcus Aurelius, the Senate's relevance steadily diminished. Emperors became increasingly hostile towards its members and consulted the body less frequently.[3] By the Severan dynasty, the senatorial class found itself increasingly detached from the actual machinery of government, with administrative functions progressively assumed by equestrians and other imperial bureaucrats.[3]

Diocletian's Reforms and Finality

Around 300 AD, Emperor Diocletian's constitutional reforms delivered a decisive blow to the Senate's remaining theoretical powers. He asserted the Emperor's right to assume power without the Senate's consent, thereby stripping it of its status as the ultimate repository of supreme authority. These reforms effectively ended any illusion of the Senate possessing independent legislative, judicial, or electoral powers.[3]

Despite the drastic curtailment of its influence, the Senate did retain some specific legislative powers:

  • Oversight of public games in Rome.
  • Regulation of the senatorial order itself.
  • The power to try treason cases.
  • The ability to elect some magistrates, though always contingent on imperial permission.[3]

In the Empire's twilight years, the Senate occasionally attempted to assert its will, such as appointing Eugenius as emperor, though he was later defeated by Theodosius I. It also remained a bastion of traditional Roman religion amidst the rise of Christianity, repeatedly advocating for the return of the Altar of Victory to the senatorial curia.[1]

Post-Imperial Era

Under Barbarian Rule

Even after the fall of the Western Roman Empire, the Roman Senate continued to function under barbarian chieftains like Odoacer and later Theoderic the Great, who established the Ostrogothic Kingdom. Under these new rulers, the Senate's authority paradoxically saw a considerable rise, as barbarian leaders often sought to protect and utilize the institution. This period witnessed the prominence of influential Roman senatorial families, such as the Anicii, with the princeps senatus (leader of the Senate) frequently serving as a key advisor to the barbarian ruler.[10]

A striking example of the Senate's continued influence was its installation of Laurentius as antipope in 498 AD, despite both King Theoderic the Great and Emperor Anastasius I Dicorus supporting Pope Symmachus. This demonstrates a degree of independent action even under barbarian oversight.[10]

Decline and Dissolution in the West

The peaceful coexistence between senatorial and barbarian rule was shattered by the Ostrogothic leader Theodahad, who initiated an uprising against Emperor Justinian I, taking senators as hostages. Several senators were executed in 552 AD in retaliation for the death of the Ostrogothic king Totila.[10] Although Rome was eventually recaptured by the Imperial (Byzantine) army, the Senate, and indeed classical Rome itself, had been mortally wounded by the protracted Byzantine-Ostrogothic War. Many senators perished, and others fled to the East, choosing to remain there due to favorable legislation from Emperor Justinian, who simultaneously abolished virtually all senatorial offices in Italy.[10]

The Roman Senate's importance rapidly waned. Pope Gregory I, in a sermon from 593, lamented the near-complete disappearance of the senatorial order. While its exact end date in the West is unclear, the Senate is known to have acclaimed new statues of Emperor Phocas and Empress Leontia in 603 AD.[11] The institution definitively ceased to exist by 630 AD when the Curia Julia, its historic meeting place, was transformed into a church by Pope Honorius I.[11]

The Eastern Continuation

While the Roman Senate in the West faded into history, a distinct Byzantine Senate continued to exist in the Eastern Roman Empire's capital, Constantinople. This institution, initially established during the reign of Constantine I, maintained its presence and functions until at least the mid-14th century, a testament to the enduring legacy of Roman political structures in the East.[10]
