every emergency power is born with the promise of being returned. what happens when a state suspends its entire constitution “just for a year” to fix a technical problem is one of the oldest political lessons rome’s memory preserves, and one of the most stubborn: those who come in to govern without checks rarely want to leave.
year 451 bce. the republic had been trapped for decades in its internal conflict between patricians and plebeians, and the deepest grievance was neither economic nor military: it was legal. roman law was not written down. it lived in the memory and interpretation of the patrician magistrates: they handed down sentences invoking an oral custom that only they knew. for a plebeian, that meant appearing before a judge who was at once legislator, interpreter and interested party. ever since the tribune gaius terentilius harsa’s proposal in 462 bce, the plebs had demanded the one thing that would level the playing field: that the laws be set down in writing, public, identical for all.
the senate agreed, but at an extraordinary price. to draft the code, the ordinary magistracies — consuls included — would be suspended, as would the right of appeal to the people, the provocatio, which was the citizen’s shield against arbitrary punishment. all power would pass to a commission of ten men, the decemviri legibus scribundis, “the ten for writing the laws”. during their first year they delivered: they worked in earnest and produced ten tables of law that were displayed to the people and approved in the comitia centuriata. the work seemed a resounding success.
rome had killed the kings, and now had ten tyrants stepping on its neck.
the trouble began when they declared the work unfinished and asked for a second year in office. a new college of ten was elected, and at its head stood the figure that tradition turned into the archetypal villain of the early republic: appius claudius. a patrician of one of the most powerful stocks in rome, he had been a decemvir in the first commission and manoeuvred to be re-elected, this time surrounding himself with docile allies. with control of the college in hand, the decemvirs did the simplest and most dangerous thing: when their term expired, they simply did not leave.
the emergency machinery became a regime. the decemvirs surrounded themselves with armed guards, governed without convening new elections and kept the provocatio suspended, so that their sentences allowed no appeal. tradition attributes to them purges of opponents, confiscations of land and unpunished violence against plebeians who no longer had anyone to turn to. rome had expelled the kings half a century earlier precisely so as not to submit again to a single, uncontrolled power; now it found itself dominated not by one, but by ten.
tradition wreathed even the origins of the code in an aura of prestige. livy tells us that, before drafting the tables, rome sent an embassy to athens to study the laws of solon and other greek cities, so that the first written roman law would draw from the legislative wisdom of greece. modern historians seriously doubt that voyage — it smacks of an erudite legend designed to ennoble the code — but the anecdote reveals something true: for the romans themselves, the twelve tables were no ordinary norm, but the founding act of their legal life. four centuries later, livy (iii.34.6) would call them fons omnis publici privatique iuris, “the source of all public and private law”. schoolchildren would still memorise them as the basis of their civic education when almost no one any longer remembered the decemvirs.
modern history reads the episode with caution. traditional chronology places the first decemvirate in 451 and the second in 450, but the details — the names, the division into two colleges, the wickedness concentrated in appius claudius — belong to the later annalistic reconstruction, which tended to personify political conflicts as clear-cut heroes and villains. what almost nobody disputes is the core: from this process emerged the twelve tables, the first written code of rome and the foundation stone of the whole western legal tradition. the price of fixing the law in writing was handing the state over to a commission that refused to give it back.
that contradiction — just laws born of an unjust government — could not be sustained for long. the regime of the decemvirs would fall, but not through a debate in the senate or a vote. it would be brought down by a single private crime, so atrocious that it would set a whole army against its own rulers.
