Military tribunes were elected in place of the consuls in half the years from 444 to 401 BC, and in each instance, all of the tribunes were patricians; nor did any plebeian succeed in obtaining the consulship. The number of tribunes increased to four beginning in 426, and six beginning in 405. At last, the plebeians elected four of their number military tribunes for the year 400; others were elected in 399, 396, 383, and 379. But apart from these years, no plebeian obtained the highest offices of the Roman State.
