By the 130s BC Roman politicians were saying that the men who conquered the world had no land in it, and the interesting question is how much of that was true.
The previous lesson followed the armies out and the money back. This one stays in Italy. It is the only lesson in this course where the ancient explanation and the modern evidence pull hard against each other, so it is worth being careful, because the reformers of the next lesson acted on the ancient explanation and the consequences followed from what they believed as much as from what was the case.
The diagnosis the Romans gave
Appian and Plutarch tell the same story, and it is coherent. The rich occupied more and more of the public land, the ager publicus taken from defeated Italians, beyond the legal limits. They worked it with slaves rather than free tenants, because slaves could not be conscripted and so were never taken away at harvest. The free smallholders, absent on campaign for years at a time, came home to debt and sold up, and drifted to Rome, where they had votes and no property. Since only a man with property could serve in the legions, the state was destroying its own recruiting base every time it won a war.
Plutarch adds the scene that made the case famous: Tiberius Gracchus travelling through Etruria on his way to Spain in 137 BC, seeing a countryside worked by imported slaves and almost empty of free inhabitants, and deciding that something had to be done.
Three parts of that account can be checked against independent evidence, and they hold up. Service abroad really was long and unpopular: the Spanish wars ran with little pause from 197 to 133 BC, and the levies of 151 and 138 produced riots in Rome, on one occasion with tribunes jailing a consul. Slaves really did arrive in numbers: 150,000 were enslaved in Epirus alone in 167 BC, and modern estimates put the slave population of Italy at the end of the Republic somewhere around a million, which on the usual estimates of Italy's total population is of the order of a fifth to a quarter of everyone alive there. And the property qualification for legionary service really did fall, from the 11,000 asses of the old fifth class to Polybius's 4,000 in the second century BC and to a figure of 1,500 by the time of Marius, a reduction of more than seven to one.
Cato's farm
The best single document is a handbook. Cato the Elder wrote De Agri Cultura around 160 BC as practical advice to a man with capital, and it describes without embarrassment the kind of estate the reformers complained about: slave-worked, market-oriented, and specialised in wine or oil rather than grain.
Cato staffs a 100-iugera vineyard with sixteen people: an overseer, his wife, ten labourers, a ploughman, a muleteer, a man for the willows and a swineherd. He also gives instructions on selling worn-out oxen and old or sickly slaves.
Example. A hundred iugera is about 25.2 hectares. Roman colonial allotments to settlers were often in the range of two to seven iugera. Work out what Cato's estate represents.
At the upper end of the allotment range, a hundred iugera is about fourteen family farms, and at the lower end it is fifty. The labour figure is 16 people on 100 iugera, or 0.16 workers per iugerum, which is thin compared with fourteen peasant households working the same ground, so the estate supports far fewer people on the same land. That is the mechanism the reformers were pointing at, stated in a form Cato would have recognised and approved: the villa is more profitable per unit of capital and it carries fewer men, and men are what the legions need. Notice also what Cato's list does not contain: any free tenant, and any product for local subsistence.
Now you. The property qualification for legionary service fell from 11,000 asses to about 1,500 over roughly a century. Two readings are possible. What are they?
Answer
Either the citizens were getting poorer, so the state had to reach further down to find the same number of soldiers, or the state's demand for soldiers was growing faster than the population that met the old threshold, so it lowered the bar to reach men who were no poorer than before. The first is the Gracchan reading and the second is compatible with a stable peasantry and an empire with more armies to fill. The two are not exclusive and the evidence does not cleanly separate them. What the falling threshold does prove is that the recruiting system was under pressure for one reason or the other, which is why every serious politician of the next generation had a policy about land.
What the census says
The censors counted citizens every five years, and the totals survive for much of this period. They are the closest thing the Republic has to a statistic.
The count stands at 337,022 in 164 BC and drifts down for thirty years, reaching 317,933 in 136 BC, a fall of 5.7 per cent at a time when nothing suggests a demographic collapse. Then, after the land commission set up in 133 BC had been working for several years, the census of 125 BC returns 394,736, an increase of 75,913 over the count of 131 BC, which is 23.8 per cent in six years.
Example. Interpret that jump of 75,913.
Populations do not grow by a quarter in six years, so the change is in registration rather than in births. The obvious candidate is the land commission: a man given a plot has property, property makes him liable to service and worth registering, and he now has a reason to present himself to the censors. On that reading the figure is the best evidence anywhere that the Gracchan programme actually distributed land to tens of thousands of people, which no narrative source states in numbers. The caution is that census procedure changed over time and that the surviving totals come to us through summaries of Livy, so a change in what was counted cannot be excluded. Even allowing for that, a jump of this size at exactly this moment is hard to explain by anything but the commission.
Now you. The census of 70 BC gives about 910,000 citizens and the census of 28 BC, reported by Augustus himself, gives 4,063,000. What is the problem, and what turns on it?
Answer
If both counted the same thing, the citizen body grew 4.46 times in 42 years, which is an annual growth of about 3.6 per cent and impossible for a pre-industrial population, especially one that had just fought civil wars. Two solutions are current. Peter Brunt argued that Augustus counted women and children while the Republic counted adult men, so the totals are not comparable and Italy's population was modest. Elio Lo Cascio argued that both counted adult males and that the Republican censuses were badly under-registering, so Italy was far more populous than Brunt allowed. What turns on it is the whole picture of this lesson: on the low count, Italy was crowded with too many people for its land, and on the high count, it was not, and the crisis of the second century BC has to be explained by the distribution of land rather than by a shortage of it.
What the ground says
Since the 1950s, field survey has walked Italian landscapes collecting the pottery scatters that mark ancient settlement, and the results complicate the literary picture rather than confirming it.
Slave-run villas of Cato's type are real and are found where the sources say they were, in coastal Etruria, Latium and Campania, close to Rome and to ports. Elsewhere, surveys in inland Samnium, in the Biferno valley and in parts of the south find small sites persisting in numbers through the second century BC, which is not what wholesale displacement of the peasantry would look like.
So the honest summary is regional. The villa economy expanded in the best-connected parts of Italy, at the expense of small holders there, while much of the interior went on being farmed by families. The crisis the Gracchi described was real where they saw it, along the roads a Roman politician actually travelled, and it was not uniform across Italy.
That correction matters less than it might, for a specific reason. The recruiting crisis did not require the whole peninsula to be depopulated. It required only that the number of men with enough property to qualify for the legions stopped keeping pace with the number of legions Rome wanted to field, and that is consistent with the survey evidence and with the falling threshold together.
The city that filled up
The other half of the change is urban. Rome by the late second century BC was a city of several hundred thousand people, growing towards the near-million of Augustus's day, and it could not feed itself from its own hinterland. Grain came from Sicily, later from Africa and Egypt, and the price of it in the city became a political question with a constituency attached.
The men in that city were citizens with votes, concentrated in the four urban tribes, available on any given day when a tribal assembly met. Everything in the earlier lesson on how an election was won now acquires a new significance: for the first time there was a large, poor, permanently present electorate in the one place where votes were cast, and any politician willing to address its grievances had an instrument nobody had had before.
Example. Appian says the free peasantry was displaced and Italy filled with slaves. Field survey shows small farms persisting across much of the interior. How should the two be held together?
By asking what each source can see. Appian, writing much later from second-century sources, reports what a politically engaged Roman believed about the parts of Italy that Roman politics could see: the coastal plains, the estates of senators, the roads to the ports. Survey sees whole landscapes indifferently, including the ones nobody wrote about. Neither is lying, and the disagreement is mostly about scope. The correct statement is that a real transformation of the best land was generalised into a claim about Italy, that the generalisation was believed by the men who acted on it, and that beliefs about a crisis are themselves historical causes.
Now you. Suppose Lo Cascio is right and Italy's population was much larger than Brunt allowed. Does the Gracchan land programme still make sense?
Answer
Yes, and its meaning changes. On the high count, land is scarce relative to people, so redistribution is a fight over a genuinely fixed resource, and the resistance of the occupiers is about real value rather than about principle. On the low count, redistribution is a technical fix to a recruiting problem in a country with land to spare, and the resistance looks more like class politics than economics. Either way there are more people wanting plots than there are plots, and the commission's work still shows up in the census jump. It is a good example of a case where the historical judgment is robust to an unresolved quantitative dispute, and worth noticing, because that is not always so.
Where this leaves the Republic
Put the pieces together. Italy's most valuable land was increasingly worked by slaves for absentee owners. The public land, which in law belonged to the Roman people, was in practice occupied by the men who sat in the Senate. The property qualification for the legions had fallen sevenfold. The city was full of citizens with votes and no land, and the countryside was full of veterans with claims and no compensation.
Every one of those is a problem the constitution had no procedure for solving, because solving any of them meant taking something from the men who ran the state. In 133 BC a tribune tried, using the assembly's legal power to legislate over the Senate's head. What happened to him is the next lesson, and it is the moment the Republic's political vocabulary changes.
