What happened

For decades after the Republic's founding, Rome's plebeians (commoners) had no written law to appeal to. Patrician judges, who alone knew and interpreted the unwritten customs, could and did rule arbitrarily, especially against debtors. Plebeians had already walked out of the city once before, in 494 BCE, camping on the Aventine Hill and refusing to return until the patricians granted concessions, including the office of tribune of the plebs. Decades later they demanded the patricians make the laws public, and in 451 BCE the Senate suspended normal offices and appointed ten men, the decemviri, with full consular power specifically to collect, draft, and publish a law code. The commission produced ten tables of law, and after a second commission added two more, the completed Twelve Tables were engraved on brass and fixed up in public view in the Forum, so that the law itself, not just a patrician's memory of it, was what governed a case.

Why it matters

The Twelve Tables did not make Roman law fair. Many of its actual provisions still favored creditors and patricians, and one clause banned intermarriage between patricians and plebeians outright, a ban the tribune Gaius Canuleius forced the Senate to repeal only a few years later, in 445 BCE. What changed was that the law was now the same for everyone and could be read rather than simply pronounced by a patrician judge, and that public, fixed text became the reference point Romans appealed to for centuries afterward. The second decemviri commission also refused to give up power at year's end, triggering a second walkout to the Aventine and the restoration of the tribunate, showing that writing the law down did not by itself end the conflict between the orders.

How we know

The main narrative comes from the Roman historian Livy, writing roughly four centuries after the events, so the specifics of speeches and personalities are not treated as verbatim history by modern scholars. But Livy directly names the decemviri's own commission title and states plainly that the finished code was engraved on brass and posted publicly, an institutional detail Roman antiquarians preserved carefully because the Twelve Tables remained a real legal reference long after 450 BCE, and fragments of the actual wording still survive today through later legal writers who quoted them.
