It is important to note that, in referring to the Roman state, res publica did not identify any particular form of government and was still used to refer to the Roman state long after the Roman Republic had ceased to exist and when Rome was ruled by emperors. For example, in the dedication by Pliny the Elder (23–79) of his Historia Naturalis (Natural History) to the future Emperor Titus, he congratulates Titus on his service to the state, this term being expressed by res publica, written in 77, more than a century after the end of the Roman Republic. (Pliny, Natural History, 3.)
The term res publica clearly, therefore, carries no implication of democracy even though it is based on the word populus, meaning “the people,” The acronym SPQR, for Senatus Populusque Romanus (The Roman Senate and People), a corporate designation of the Roman state, likewise carries no implication of democracy and is also not associated with a republican form of government. In fact, it is first encountered only in the late Republic and continued to be used well into Imperial times. Both the Arch of Titus, dating from 81 (CIL VI 945), and the Arch of Septimius Severus, constructed in 203 (CIL VI 1033), were dedicated to the memory of these emperors by The Roman Senate and People, the latter well over two centuries after the demise of the Roman Republic.
From One Brutus to Another
Whatever the precise explanation may be for the overthrow of the monarchy, there can be no doubt about the nature of the republic which replaced it. Far from being a democracy, it was controlled by a hereditary aristocracy that gradually morphed into an oligarchy. “Oligarchy,” from the Greek, means literally “the rule of the few,” whereas the literal meaning of “aristocracy,” also of Greek origin, is “the rule of the best.” Aristotle (384–322 BCE) used both terms to refer to minority rule, aristokratia being the “good” form and oligarchia the “bad” or “perverted” form. (Arist. Politics III.7.) My own usage of these terms is rather different. Aristocracy refers to rule by a hereditary elite and also to the membership of that elite, while “oligarchy” is used to refer to a non-hereditary ruling elite. And it is worth noting the Latin term res publica or respublica (republic) did not refer to the type of government or power structure but was a much more general term meaning essentially “the Roman state.” (See sidebar).
According to our sources, the Latin word rex (king) and the whole idea of monarchy were taboo in the Roman Republic (and long afterward), which makes perfect sense because what an oligarchy dreads most is a strong ruler supported by the masses. But, as the history of the late Republic demonstrates, it would be a mistake to assume that this fear of monarchy was shared by the populace at large. Indeed, in times of crisis, the ordinary people would look to a strong leader to champion their cause against the oligarchy.
The Republican constitution, meaning the creation of the ruling oligarchy, was carefully constructed so as to prevent power from being concentrated in the hands of any one person. One of its main features was collegiality, or shared power, together with short terms of office, and rotation. The chief offices and institutions of state included the following:
Consuls: The king was replaced by two consuls with equal authority elected for a year at a time, each with the right to veto the other’s actions. They alternated in holding supreme power imperium (supreme power) month by month. According to tradition, the consuls (possibly originally called praetors) had to be patricians until the Lex Licinia Sextia of 367 BCE threw the consulship open to plebeians as well, and the Lex Genucia of 342 BCE, which reserved one consulship for a plebeian every year but permitted both consuls to be plebeians (Livy 7.42.), The Lex Genucia also laid down the rule that a ten-year gap had to be left before an office-holder could be elected to the same office for a second term, but this was repealed in 217 BCE. (Livy 27.6.7.)
Other magistracies: All other regular executive magistracies, such as the praetorship, aedileship, and quaestorship, were similarly collegiate, being shared by several office-holders at the same time. They were elected for a year at a time and could be re-elected but only after a gap of ten years.
Tribunus plebis (Tribune of the plebs): An important office, traditionally said to have arisen out of the conflict between patricians and plebeians, known as the Conflict or Struggle of the Orders, which ended after about two centuries in 287 BCE. The tribunes, 10 in number after 457 BCE, were elected by the Concilium Plebis, an assembly of all Roman citizens except patricians. Tribunes could convene this body and preside over it. By the third century BCE, the tribunes also had the power to summon the Senate and put proposals to it. Provocatio (appeal against execution or flogging without trial) could be addressed to a tribune, but details are sketchy. A really important power held by tribunes was intercessio, the power to veto the action of any magistrate and even acts of the Senate, but no magistrate could veto the action of a tribune. Coupled with sacrosanctitas, or inviolability of their persons, a breach of which was punishable by death, these powers made tribunes extremely influential. According to persistent tradition, the tribunate was created to protect the original plebeians in the Conflict of the Orders.
These plebeians, or some of them, eventually fused with the patricians to form a composite patricio-plebeian aristocracy. The dating is much disputed, and it appears that it was only in 173 or 172 BCE that both consuls were plebeians for the first time (Cornell 1995, p. 337 f.) However, there is really no need to dismiss Livy’s detailed account. A simple explanation may be that, though it was constitutionally permissible from 342 BCE for both consuls to be plebeians, this law was not acted on until 173 BCE. The Lex Genucia was, after all, according to Livy, purely permissive and not mandatory. In other words, it allowed both consuls to be plebeians but did not require it. What is more significant is that, from 343 BCE onward, one consul was always a plebeian. These plebeians therefore formed an integral part of the senatorial aristocracy or oligarchy. So, who then made up the plebs whom we encounter in political activity in the late Republic, particularly from the time of the Gracchi, two hundred years after the Lex Genucia? Were they simply those plebeians from the early Republic who had been left behind when their more fortunate brethren joined the aristocracy? This seems unlikely as this later plebs, sometimes termed plebs urbana (urban plebs), is often portrayed as a mob, or what Cicero described as faex Romuli (the dregs of Romulus).” (Cicero Ad Att. 2.1.8.) Though created to protect the interests of a very different plebs in the early Republic, the tribunate was used to good effect by demagogues like the Gracchi in the late Republic on behalf of this more desperate plebs. In 48 BCE, tribunicia potestas (tribunician power) was granted to Julius Caesar, who, as a patrician was ineligible to hold the actual tribunate. In 23 BCE, this same power was bestowed by the Senate on Augustus for life, in addition to the sacrosanctitas of a tribune which he already had. Tribunician power was an important signal of the emperor’s identification with the interests of the lower classes, and it was routinely bestowed on every emperor, usually upon his accession.
Censor: A very senior post in charge of taking the census of citizen numbers, open only to former consuls, again shared by two equal office-holders, elected originally for five years but later for eighteen months.
Senate: This was the most important deliberative body under the Republic, made up of former holders of the different executive magistracies. Until the passing of the Ovinian Law (Lex Ovinia) in 318 BCE, senators were appointed by the consuls and, after that date, by the censors. Under Sulla’s reforms of 81 BCE, quaestors were granted automatic membership of the Senate. Consuls were invariably drawn from the ranks of the Senate.
Assemblies: Roman citizens were members of several Assemblies, arranged in slightly different ways: the Comitia Curiata, Comitia Centuriata, and Comitia Tributa. It was the Centuriata alone, in which the citizens were arranged along military lines, that had the power to declare war and to elect the highest-ranking magistrates, the consuls, praetors, and censors.
