The Trebonian plebiscite, 448 or more probably 401, has already been discussed.[1788] The interest of the plebs in enhancing the dignity and importance of their own order manifested itself not only in this act but also in the Canuleian plebiscite of 445, which reëstablished conubium between the patricians and plebeians after it had been forbidden by a law of the Twelve Tables.[1789] Closely related is the centuriate law of the same year for the institution of tribunes of the soldiers with consular power to be elected indiscriminately from the two social classes.[1790] Slightly earlier, if we may trust our sources, the people were given an unwonted opportunity to share in the decision of questions relating to foreign affairs; and the favor fell to the comitia tributa under patrician presidency, which had convened in this form for the first time in 447 for the election of quaestors.[1791] The question before this assembly in 446 was the arbitration of a dispute between Ardea and Aricia concerning a piece of territory. The contestants brought the case before the Roman senate, which usually decided such matters on its own responsibility, but which in this instance requested the consuls to refer the business to the tribes. The aim of the senate must have been to throw the odium of the decision upon the people, who, disregarding the claims of the two contestants, lost little time in adjudging the disputed property to Rome.[1792] This act did not serve as a precedent for further interference of the assembly in foreign affairs; and when in 427 the people acquired the right to declare an offensive war,[1793] the function fell to the centuries rather than to the tribes. Apart from this gain the comitia made little progress[1794] in the period between the Canuleian and the Licinian-Sextian legislation, 445-367. Few legislative acts of the tribes are recorded: the plebiscite which provided in a time of famine for the election of a prefect of the market, 440;[1795] the historically questionable plebiscite which forbade candidates for office to whiten their garments, 432;[1796] the plebiscite of 414 for the creation of a special court to try a case of murder;[1797] the act, probably a plebiscite, which forbade a patrician to dwell on the Capitoline, 384.[1798]
