The Roman Republic began by removing one man from a machine that had been built for him, and keeping every other part of it.
That is the first thing to understand about the constitution this course takes apart. It was not designed. It was a monarchy with the monarch subtracted, patched for four and a half centuries by people solving the argument in front of them, and no Roman ever read it as a document, because there was no document. This lesson assumes nothing about Rome. It sets out what the kings left behind, and, first, how much of the story can be believed at all, since that governs everything said about the next two hundred years.
Three centuries of silence
Rome dated its own founding to 753 BC and the expulsion of its last king to 509 BC, both dates fixed by scholars of the first century BC working backwards. The first Roman to write a history of Rome was Quintus Fabius Pictor, a senator who wrote in Greek around 200 BC. Between the fall of the monarchy and the first Roman account of it lie 309 years. At a conventional twenty-five years to a generation, that is a dozen generations of transmission before anyone wrote a line.
The two long narratives that survive are later still. Livy began his history in the 20s BC, 482 years after the events of his second book, and Dionysius of Halicarnassus was writing in Rome at the same time. Both had earlier annalists to draw on, and those annalists had the pontifical records, the priestly year-by-year notes of prodigies, eclipses, grain prices and magistrates. Livy himself reports that the Gauls burned the city in 390 BC and that the records went with it, which he offers as the reason the early centuries are thin.
So the working rule is not that early Roman history is fiction. It is that the further back a claim sits, the likelier it is to be a later reconstruction dressed as a fifth-century fact. Speeches are invented, as every ancient historian invented them; battles multiply; institutions get pushed back in time so as to look venerable. What survives this scepticism best is the spine: the list of annual magistrates, the fasti, kept because the Romans dated their years by it, and the physical city.
What the ground says
Archaeology is the check on the literary tradition, and on the question of kings it is unusually direct. Under the Comitium in the Forum sits the Lapis Niger, a black stone paving over an inscribed pillar of the mid sixth century BC. The Latin is archaic and broken, but the word recei, a dative of rex, is legible on it. There was a king in Rome, in the sixth century, and he was a public figure whose title appeared on a monument in the political centre of the city.
The other check is the temple of Jupiter Optimus Maximus on the Capitoline, dedicated by tradition in the Republic's first year but built by the last kings. Its podium, uncovered under the Palazzo Caffarelli, measures roughly 53 by 63 metres, a footprint of about 3,300 m². The Parthenon's stylobate is 30.9 by 69.5 metres, about 2,150 m². Sixth-century Rome, which the literary tradition treats as a modest place, laid foundations half again as large as classical Athens would later manage on its acropolis, and it did so with the labour and the organisation of a state rather than a village.
That is the shape of the evidence throughout: the tradition's stories are doubtful and its framework is often right.
Example. Livy names seven kings ruling from 753 to 509 BC. Test the list by arithmetic before testing it by argument.
Seven reigns across 244 years gives a mean of 34.9 years each. The English throne between 1066 and 1901 passed through thirty-five or thirty-six holders in 835 years, depending on how joint reigns are counted, which is 23 to 24 years apiece, and that is a hereditary succession where a son often follows a father in youth. Roman kingship was not hereditary: Livy has kings chosen, and two of them murdered. A non-hereditary throne should turn over faster than a hereditary one, not fifty per cent slower. Either the list has lost kings or the founding date is too early. The arithmetic cannot say which, and it does say the list as given is not a complete record.
Now you. Dionysius and Livy both put the first pair of consuls in 509 BC and name them. What does the existence of the consular list establish, and what does it not?
Answer
It establishes that a list existed, was kept continuously enough to date by, and was believed in the late Republic to run back to the sixth century. That is real evidence for an early annual magistracy, since a fabricated list of hundreds of names would have had to pass the families whose ancestors it named or left out. It does not establish that the earliest names are right, that the office was called the consulship then, or that 509 is the correct year. Livy preserves a rival tradition, from the Linen Books, of a praetor maximus who drove a nail into the Capitoline temple each year.
What a king was
The Roman king was not a monarch in the medieval sense, with a court and a bureaucracy. He was a commander, a judge and a priest, and his power was made of three things the Republic inherited intact.
The first was imperium: the right to command, to levy an army, to lead it, to compel obedience, and to punish. It was visible. A holder of imperium walked the city preceded by lictors, attendants carrying the fasces, a bundle of rods with an axe in it, the rods for beating and the axe for killing. Nobody had to explain what it meant.
The second was auspicium, the right to ask the gods whether a proposed action had their approval. Roman public business could not begin without it, and this was not decoration: it gave its holder the power to stop an assembly, a battle or an election by reporting an unfavourable sign, and the Republic would use that lever constantly.
The third was the machinery of consent around him. A council of elders, the senatus, advised. An assembly of citizens organised by their thirty curiae confirmed the king's power by a law, the lex curiata de imperio. Neither could initiate anything, and both would still exist under the Republic, with the same names.
Subtraction, not replacement
Now look at what the men of 509 actually did. They did not abolish imperium; they split it between two holders and made it expire after a year. They did not abolish the auspices; they handed them to the new magistrates. They did not abolish the Senate or the assembly; they kept both and enlarged the Senate's role, since a magistrate who lasts twelve months needs advisers who last for life.
The clearest proof that they understood themselves to have removed a person rather than a function is the priesthood invented to hold the leftovers. The king had religious duties only a king could perform, so the Republic created a rex sacrorum, a king for sacred purposes, who carried out the rites and was barred from every political office. The title was too dangerous to leave attached to power and too necessary to abolish, so they cut it in two.
The word for what they created was res publica, the public thing, the property or business of the people, as opposed to something belonging to one household. It is not a word for a set of institutions. It is a claim about ownership.
The fear that never went away
Because the Republic was defined against a person, its politics kept a permanent charge that no modern constitution has: aiming at kingship, adfectatio regni, lethal and needing no evidence beyond behaviour.
The tradition preserves three early cases and they follow one pattern. Spurius Cassius, three times consul, was executed in 485 BC after proposing to distribute land to the poor. Spurius Maelius, a rich grain dealer, was killed in 439 BC after selling grain cheaply in a famine. Marcus Manlius Capitolinus, credited with saving the Capitol from the Gauls, was thrown from the Tarpeian Rock in 384 BC after paying the debts of the poor. The details are exactly what annalists elaborate, but the pattern is the political vocabulary of the class that told the stories: a man who acquires a personal following among the poor is a king in waiting.
That charge was still live 465 years after the expulsion. When a crowd hailed Caesar as rex in 44 BC, he answered that he was not king but Caesar, and a few weeks later he was dead, stabbed by men who told themselves they were repeating 509.
Example. On the tradition, Spurius Maelius bought grain at his own expense in the famine of 439 BC and sold it below cost to the plebs; the Senate appointed a dictator, and Maelius was killed without trial by the dictator's master of horse. What is the episode good evidence for?
Not for Maelius's intentions, about which the tradition reports only what his enemies said, and not for the constitutional detail, which is the kind of back-formation later writers were fond of. It is good evidence for the political grammar of the aristocracy that preserved the story, and that grammar is unambiguous: private generosity to the poor, done outside the magistracies, was read as a bid for personal power, and killing the man who tried it was remembered as legitimate rather than as murder.
Now you. At the Lupercalia of 44 BC, Mark Antony twice offered Caesar a diadem, the Greek badge of kingship. Caesar twice refused it and had it carried to the temple of Jupiter, saying Jupiter alone was king of the Romans. What does the scene tell you, and what does it not?
Answer
It tells you the title was still unusable in public five centuries after the expulsion, and that Caesar, who by then held powers no king had needed, judged a staged refusal worth the trouble. The vocabulary had outlived the thing: Romans would take the substance of monarchy from a man careful to reject the word. It does not tell you whether Caesar wanted the crown or whether the offer was arranged, since our sources disagree and both readings were current within a year. What a staged scene reliably reveals is what the stagers thought the audience believed.
How this course reads its sources
Two writers do most of the work in what follows, and they are unequal. Polybius, a Greek politician deported to Italy in 167 BC and taken into the household of the Scipios, wrote to explain to Greeks how Rome conquered the Mediterranean in fifty-three years. He interviewed participants, walked the ground and used Roman family archives, and for the third and second centuries BC he is a first-rate contemporary witness with a first-rate analytical mind. He is also the friend of one of the great houses, which shows.
Livy, writing under Augustus, is a different instrument. He works from earlier annalists, rarely marks where they differ, and writes to a moral scheme in which Rome rises through virtue and falls through wealth. For events before about 300 BC he preserves a tradition rather than reporting facts, and he sometimes says so. For the last century of the Republic we lose him almost entirely and rely on Appian, Plutarch, Sallust, and on the one archive nobody could tidy: the letters of Cicero, written week by week with no idea how the story ended.
The rule for the rest of this course is to ask of every claim who could have known it and how it reached us. A tax figure in Polybius, a land law quoted on bronze, a census total in the fasti and a deathbed speech in Livy are four different kinds of statement, and only the last one is free.
Example. Two statements about the fifth century BC: (a) the consular fasti record two magistrates for 509 BC, and (b) Brutus condemned his own sons to death for conspiring to restore the Tarquins, and watched the executions. Which is the stronger evidence?
The first, by a wide margin. The fasti are a working document, used to date contracts, priesthoods and family honours, kept and consulted by people with a motive to police it, and its earliest entries are constrained by the entries after them. The second is a scene: it has an audience, a moral, no possible witness who could have carried the detail through twelve generations, and a hero whose descendants were still trading on the family's tyrannicide in 44 BC. That does not make it invented; it makes it a story about what Romans valued rather than a record of what happened.
Now you. Polybius describes the constitution as he saw it working in the 150s BC, and projects the same description back onto the Rome of 216 BC. Where should you trust him, and where be careful?
Answer
Trust the account of how the institutions worked in his own lifetime: he watched them, knew the men, and wanted to explain the mechanism accurately to Greeks. Be careful with the projection backwards, which assumes the constitution stood still across sixty years that included the Hannibalic war and the conquest of the east, and be careful with the frame itself. The mixed constitution was a Greek theory before Polybius applied it to Rome, and a theory a writer brings with him tends to find its own categories in whatever it examines.
Where this leaves the Republic
The men who expelled the king inherited a working state and a single problem: a king's powers had to be exercised by somebody, and nobody could be allowed to hold them the way a king had. Every institution in the next lesson is an answer to it. Two consuls rather than one, because a colleague can say no. One year rather than a lifetime, because a term ends. A Senate that could not command and could not be ignored, and assemblies that could vote yes or no but could not propose.
None of it was planned in 509, and much of it took another two centuries to appear. What was there from the start was the intention, and the next lesson takes the finished machine apart to see what the intention cost.
