Inequality between plebeians and patricians led to a conflict known as the Struggle of the Orders. In this conflict the plebeians sought to increase their power by taking advantage of the fact that Rome’s survival depended on its army, which needed plebeians to fill the ranks of the infantry. According to tradition, in 494 B.C.E. the plebeians literally walked out of Rome and refused to serve in the army. Their general strike worked, and the patricians made important concessions. They allowed the plebeians to elect their own officials, the tribunes, who could bring plebeian grievances to the Senate for resolution and could also veto the decisions of the consuls.

The law itself was the plebeians’ primary target. Only the patricians knew what the law was, and only they could argue cases in court. All too often they used the law for their own benefit. The plebeians wanted the law codified and published. After much struggle, in 449 B.C.E. the patricians surrendered their legal monopoly and codified and published the Laws of the Twelve Tables. The patricians also made legal procedures public so that plebeians could argue cases in court. Several years later the patricians passed a law that for the first time allowed patricians and plebeians to marry one another.

After a ten-year battle, the Licinian-Sextian laws passed in 367 B.C.E. gave wealthy plebeians access to all the offices of Rome, including the right to hold one of the two consulships. Once plebeians could hold the consulship, they could also sit in the Senate and advise on policy. Though decisive, this victory did not automatically end the Struggle of the Orders. That happened only in 287 B.C.E. with the passage of the lex Hortensia, which gave the resolutions of the concilium plebis, the plebeian assembly, the force of law for patricians and plebeians alike.
