Now I should note at the outset that our sources for the Gracchi are not what we might like. Tiberius Gracchus’ year as tribune was in 133 and the late second century is a period where our best sources largely cut out. Polybius, of course, was writing in the 140s and so is unavailable for later events. Livy, always useful, did write the history of this period, but it is lost save for extremely brief summaries of his books known as the Periochae. Instead, we’re reliant primarily on Plutarch and Appian. Both sources are writing much later, in the second century AD and are writing in a context where we might question if we’re getting an entirely straight narrative. As I’ve noted before, Plutarch’s biographies in his Parallel Lives (of which there is one for Tiberius Gracchus and one for Gaius Gracchus) are intended to be moralizing essays rather than straight historical accounts and Plutarch is not above bending the truth to fit his narrative; he also tends to leave out details if they don’t fit his narrative.

Meanwhile, as D.J. Gargola has noted, Appian is also bending his account of Tiberius Gracchus’ reforms, in particular by presenting the Lex Sempronia Agraria as an entirely traditional, conventional response to a pressing crisis.¹ But in fact, the provisions of the Lex Sempronia Agraria were not traditional: no similar law (save for a re-enactment by Gaius Gracchus) – had ever or would ever be passed in Rome and the legal precedent that Appian presents as providing the foundation for Tiberius’ law appears to be at least substantially an anachronistic invention. Meanwhile, the crisis Appian thinks Tiberius Gracchus thought he was addressing probably didn’t exist in the form he understood it.

But that’s what we have, so it is what we must work with. And we should note that both Plutarch and Appian are quite favorable to the Gracchi, even though both men were clearly very controversial in their day. So in a sense this is a reverse of the situation we had with Cleopatra, where we had to contend with relentlessly negative sources: here the sources are broadly positive.

So, on with what we know.

Tiberius Gracchus was elected tribune in 133. His election was already unusual in that he seems to have run on something like a program (land reform, which we’ll get to); Romans generally ran on character and background rather than promising specific political actions if elected, so this was unusual. Part of the reason for it was doubtless that Tiberius Gracchus’ political fortunes were in difficulties. Now we should note here that while Tiberius Gracchus was a plebian (that is, not a patrician) that doesn’t make him a political outsider: Tiberius Gracchus was not remotely a political outsider or poor man or lacking in influence. His father (also Ti. Sempronius Gracchus) had been consul in 177 and 163 and censor in 169; his father (or grandfather) was consul in 215 and 213. Our Tiberius Gracchus’ mother, Cornelia, was the daughter of P. Cornelius Scipio Africanus, the man who defeated Hannibal. Tiberius Gracchus was born into substantial wealth and influence, the sort of man whose eventual political ascent was almost guaranteed.

(Indeed, it was so guaranteed that he gets to bend the rules and hold many of his offices early. He’s quaestor at just 26, which implies that he started his military service at 15 or 16 instead of the normal 17, doing so as a military tribune, not a common soldier. I do think this is relevant to understanding Tiberius Gracchus: this was a man born with a silver spoon and a carefully paved, flat-and-easy road to power and influence laid out for him by his family and his political backers, the most notable among whom was his key supporter Scipio Aemilianus (destroyer of Carthage and shortly Numantia).)

Except. Except he got wrapped up in something of a nasty foreign policy scandal during his year as quaestor, when he was assigned to the amazingly named but less amazingly capable C. Hostilius Mancinus who as consul in 137 was supposed to deal with Numantia in Spain. Mancinus blew it and got his army effectively trapped and sent Tiberius – his quaestor and the next highest ranking Roman present – to negotiate to get his army out. Tiberius did this, but the whole thing caused a great stink and a scandal at Rome (Roman armies are supposed to go down fighting, not negotiate shameful retreats!). Indeed, the Senate was so enraged they rejected the treaty and instead sent Mancinus, bound in chains, to the Numantines as part of a ritual process by which his treaty was disowned. Tiberius doesn’t get packed off to Numantia, but some of the political stink does rub off on him, so while he’s connected enough to get elected as a plebeian tribune in 133, he must know he needs a big second act to get his political career back on track, or he may never reach the consulship. That context – a political insider who had a golden ticket but must now win it back, rather than an outsider without connections – is important for understanding the reaction he is going to get.
