Since the tribunes were elected annually by the plebeians it was only natural that the plebeian assembly—which met by local groups or tribes—might remain to discuss policies and instruct the tribunes by resolution. In 471, if Livy is correct, a law was passed (the lex Publilia) which recognized the plebeian tribal assemblies as lawful, and authorized the tribunes to propose and carry resolutions in such assemblies. These resolutions (plebi scites) had of course only such force as plebeian influence gave them, but the time was to come when the plebeians were the most powerful element of the state, and when the law-making body dared not long resist the demands of plebiscites.
went farther and demanded certain reforms in the constitution. These demands were embodied in the very important Valeric Horatian laws passed by the popular (centuriate) assembly in 449. These laws granted or reaffirmed the inviolability of the tribunes, the right of every citizen to carry his appeal to the assembly in cases of death sentences, and finally enacted that plebiscites passed by the plebeian assembly should be placed before the senate and if ratified by the patres should be recog nized as law. Only a few years after the Valerio-Horatian legis lation came the lex Canuleia, itself a plebiscitum (445 B.C.), by which mixed marriages between patricians and plebeians were declared lawful, and the social exclusiveness of the patriciate broken down. In the same year with this measure, and like it in the interests primarily of the wealthier plebeians, a vigorous at tack commenced on the patrician monopoly of the consulate, and round this stronghold of patrician ascendancy the conflict raged until the passing of the Licinian laws in 367. The original pro posal of the tribune Gaius Canuleius, in 445, that the people should be allowed to elect a plebeian consul was evaded by a compromise. The senate resolved that for the next year, in the stead of consuls, six military tribunes with consular powers should be elected, and that the new office should be open to patricians and plebeians alike. The consulship was thus for the time saved from pollution, as the patricians phrased it, but the growing strength of the plebs is shown by the fact that in 5o years out of the 78 between 444 and 366 they succeeded in obtaining the elec tion of consular tribunes rather than of consuls. Despite, how ever, these discouragements, the patricians fought on. Each year they strove to secure the creation of consuls rather than consular tribunes, and failing this strained every nerve to secure for their own order at least a majority among the latter. Even the insti tution of the censorship (435), though rendered desirable by the increasing importance and complexity of the census, was, it is probable, due in part to their desire to discount beforehand the threatened loss of the consulship by diminishing its powers.
