Everything in this chapter follows from one change in how Rome raised soldiers, and it is worth stating before the names start.
The old citizen levy called up men who owned property. They served a campaign, went home to their farms, and their loyalty was to the state that had summoned them, because their livelihood was already waiting for them.
From the end of the second century the legions increasingly recruited men who owned nothing. For them the army was not an interruption of a living, it was the living, and the question that mattered was what they would get at the end of twenty years. There was no state pension. What there was, was a general who might get a law passed granting his veterans land.
So a soldier's future depended on his commander's standing in Roman politics. That is the whole mechanism. It did not make civil war inevitable, but it meant that any general with a grievance now had an instrument, and that any senate trying to discipline a general was arguing with an army that had a direct financial stake in his survival.
In 88 before Christ a consul named Sulla was given command of a profitable war in the east. A tribune transferred the command to his rival by a vote of the assembly, which was legal.
Sulla went to his army and marched it on Rome. His officers, with one exception, refused to go with him. The soldiers went. That is the first time a Roman army attacked its own capital, and it settled the question of who the legions belonged to in the least reassuring way available.
He took the city, had his opponents declared enemies, went east and won his war. While he was away his enemies took Rome back and killed his supporters. He returned in 82, won a civil war, and had himself made dictator, an emergency office that had traditionally lasted six months, with no time limit and a brief to rewrite the constitution.
Then he did something that has puzzled people ever since. He published lists. Anyone named on them could be killed by anybody, with a reward, and their property was confiscated and sold. Thousands died, including men whose only offence was owning land somebody wanted. And having done that, and having rebuilt the constitution to strengthen the Senate against tribunes and generals, he resigned, retired to the country, and died in his bed.
His constitution was dismantled within a decade. What survived was the demonstration.
The generation that followed contained three men too large for the system.
Pompey made his reputation clearing the Mediterranean of pirates and reorganising the east, and was voted commands of a scale the republic had never granted. Crassus was the richest man in Rome, with a fortune partly built on buying the property of Sulla's victims. Caesar was from an old family with no recent money, an outstanding public speaker, and enormous debts.
In 60 the three of them made a private agreement to support one another's aims and block anyone who obstructed them. It was not an office and it had no constitutional standing. Modern books call it the first triumvirate; contemporaries called it a conspiracy of three men to run the state, which is a better description.
It worked. Caesar got the consulship, then a long command in the provinces beyond the Alps, which was what he actually wanted, because a long command meant an army and a war, and a war meant plunder to pay the debts and glory to outrank Pompey.
Between 58 and 50 Caesar conquered what is now France, Belgium and part of the Rhineland, in a campaign he had no mandate to start and that he justified afterwards.
He also wrote it up himself, in a plain third person style, and published it in instalments in Rome while it was going on. The Commentaries are the earliest extended account of a European war by the man conducting it, they are still read as a model of clear Latin, and they are a campaign document. He is explaining to voters why each new war was forced upon him.
The scale of the killing was very large. Plutarch, writing much later, says a million Gauls died and a million were enslaved. Nobody can verify those numbers and both are probably inflated, but the archaeological and demographic traces of disruption are real, and Caesar himself records, without discomfort, the annihilation of communities and the sale of entire populations.
There is one episode his own account makes plain. A besieged town, out of food, expelled its women, children and old people, hoping the Romans would let them pass. Caesar refused to admit them through his lines. They stayed between the walls and the siege works and starved. He reports it as a hard necessity.
By 50 he had an army of veterans who had been with him for eight years, a fortune, and a reputation. His enemies in Rome intended to prosecute him the moment his command lapsed and he became a private citizen again.
The crisis was procedural. Caesar wanted to stand for a second consulship without first laying down his command, because laying it down would expose him to prosecution. The Senate insisted he disarm first. Both sides had arguments and both were manoeuvring.
In January of 49 he took a legion across a small river that marked the boundary of his province. Crossing it with troops was, in itself, the act of making war on the state. The phrase attributed to him at the crossing is famous and is reported differently by different sources, which is a good sign that nobody knew what he said.
The war lasted four years and was fought in Italy, Greece, Egypt, Africa and Spain. Pompey was defeated in Greece and murdered on landing in Egypt by officials calculating which way to jump. By 45 Caesar had won everything.
He then made the mistake his enemies needed. He accepted a dictatorship without a term limit, put his portrait on the coinage while alive, and accumulated honours that looked monarchical, whatever he intended by them. On the fifteenth of March in 44, in a meeting of the Senate, around sixty senators stabbed him to death.
They had no plan for the following morning. They appear to have believed that removing the man would restore the republic, because the republic was, to them, a natural order that had been obstructed. What actually existed by then was a set of armies with loyalties, and the assassins had just created a vacancy.
Thirteen more years of civil war followed. They ended in 31 with a naval battle off the Greek coast, after which Caesar's adopted heir, a young man of no military talent and exceptional political judgement, was the only power left standing.
Those thirteen years deserve more than a clause. Caesar's heir, then eighteen, first fought the Senate's war against Mark Antony, then changed sides and joined him, and the two of them plus a third man had themselves appointed to rebuild the state, this time by law. They opened with proscriptions of their own. Lists went up again, and the man whose speeches defending the republic are still set texts, Cicero, was hunted down and killed, his hands and head displayed in the forum where he had delivered them.
Then the winners fell out, as the arithmetic of two men and one position required. Antony took the east and allied himself with the ruler of Egypt, Cleopatra, who was pursuing her own kingdom's interests and has been written about ever since as though she were only a temptation. The propaganda war that followed was run brilliantly from Rome: an eastern queen, a Roman gone native, a will supposedly deposited with the Vestals and read aloud. The vote that followed declared war on Cleopatra rather than on Antony, so that it was not, formally, another civil war.
What he then built is the reason he matters more than Caesar. He did not abolish anything. Consuls continued to be elected. The Senate met. The assemblies voted. The offices kept their names, and men still competed for them and put them on their tombstones.
Underneath, he held a bundle of ordinary republican powers all at once and for life: the authority of a tribune, which let him veto anything and made his person sacred, and a provincial command covering the provinces where the legions were stationed. He controlled the army and, through Egypt and the treasury, the money. He took the title of first citizen, and later a name that had religious rather than political weight.
He also wrote his own account of it, and had it carved on bronze at his mausoleum and copied on stone across the empire. In it he says that he transferred the state back to the control of the Senate and people, and that he afterwards exceeded everyone in influence but had no more formal power than his colleagues. The second half of that sentence is technically true and the first is not, and one of the copies survives nearly complete on the wall of a temple in Turkey, so we can read the official version in his own words.
He ruled for forty five years, died in bed in the year fourteen, and was succeeded by his stepson without a civil war. That succession, more than any battle, is the moment the republic is over, because it established that the position was a thing that could be inherited.
Firm: the chronology, the offices, the wars, the legal manoeuvres. This is one of the best documented stretches of ancient history, with contemporary letters, speeches, inscriptions and coinage.
The problem is not scarcity, it is interest. Almost every major source is a participant or a partisan. Caesar wrote his own war. Augustus wrote his own record. Cicero's letters are marvellous and are the correspondence of a man positioning himself. Later historians wrote under emperors, and their portraits of the men who founded the system are shaped by what they thought of the men currently running it.
Soft: the numbers, again. Gallic dead, proscription victims, army sizes. Ancient authors did not have the data and did not need it to be accurate.
Soft: motive. Whether Caesar wanted a monarchy, and whether Augustus set out to found one, are questions our sources answer confidently and cannot possibly know. What they had was outcomes and a strong urge to read intention backwards from them.
Contested: the shape of the whole story. One influential modern reading treats the republic as having been effectively dead long before 44, arguing that a small group of families had always run it and that the change was in the size of the prize rather than the nature of the system. Another emphasises that the institutions kept working, that participation was real, and that the collapse was contingent on particular men making particular choices. The difference matters for what you take from the chapter: whether republics die of structural strain, or whether they die because specific people decide the rules do not apply to them.
