Roman magistrate

• 1. Introduction

  ›

  Roman magistrates held a kind of power that modern democracies have spent centuries trying to limit, balance, and ultimately escape. In 509 BC, when Rome expelled its last king and founded the Republic, the question at the heart of the new government was not how to create power but how to divide it. The answer was a layered system of elected officials, each carrying a defined share of authority and each capable of blocking the other. How did that system work in practice? What happened when emergencies demanded absolute command? And what became of these offices when the Republic itself fell? Those are the threads this documentary will follow.

• 2. The Roman King

  ›

  Before the Republic, one man held everything. The Roman King was chief priest, lawgiver, judge, and the sole commander-in-chief of the army. His power rested on legal precedent, but in practice it had no real restrictions. He could declare war, organize and levy troops, select army leaders, control state property, divide land and war spoils, and decree any new law unilaterally. Sometimes he submitted decrees to the popular assembly or the senate for a ceremonial ratification, but a rejection did not prevent his decree from taking effect.

  The king also managed his own staff. He chose officers and granted them powers personally. When he left the city, an Urban Prefect presided in his place. Two Quaestors served as general assistants, and during treason cases further officers assisted in proceedings. In war, the king occasionally commanded only the infantry, delegating cavalry command to the Tribune of the Celeres, the commander of his personal bodyguards.

  Death opened the most critical gap in this system. When a king died, power reverted to the Roman Senate, which elected a senator to the office of Interrex. The Interrex found a suitable nominee, presented him to the senate for initial approval, and if the senate agreed, that nominee stood for formal election before the People of Rome in the Curiate Assembly. Once elected by the people, the senate ratified the choice by decree, the Interrex formally declared the nominee king, and the new king then took the auspices before being vested with legal authority, a power the Romans called imperium.

• 3. Power Shared, Power Checked

  ›

  The Republic's founding act in 509 BC transferred the king's powers to two consuls elected each year. Two consuls, not one, and their relationship was deliberately arranged so that neither could dominate. Throughout the year, one consul ranked above the other, and that ranking flipped every month between them. They held supreme power in both civil and military matters, but each could block the other.

  Below them, the hierarchy was precise. Dictators carried the highest degree of power; then came the consul, then the praetor, then the censor, then the curule aedile, and finally the quaestor. Every magistrate could veto any action taken by a magistrate of equal or lower rank. The term the Romans used was obstruction, and the right to veto was built into the structure itself rather than granted as a special privilege.

  The most significant constitutional power a magistrate could hold was imperium, the authority to issue commands, whether military or otherwise. Only consuls and praetors held imperium. Once a magistrate's annual term expired, he had to wait ten years before serving in that office again. When that rule created practical problems, a magistrate's command powers could be extended, allowing him to function as a promagistrate and retain the authority of his office past its natural end.

  Praetors administered civil law, presided over courts, and commanded provincial armies. The censor conducted a census, and during that process could appoint people to the senate. Aediles were elected to run domestic affairs in Rome, holding powers over the markets and over public games and shows. Quaestors assisted the consuls in Rome and the governors in the provinces with financial tasks.

  Plebeian tribunes and plebeian aediles occupied a category of their own. Because they were elected only by the plebeians, not by the full Roman people, they were technically not magistrates at all. Yet their power was formidable. Plebeian tribunes could veto the actions of any ordinary magistrate. Their authority rested not on formal legal rank but on the sacrosanctity of their person. Anyone who physically resisted a tribune committed a capital offense. If someone refused to comply with a tribune's orders, the tribune could interpose his own body, an act called intercessio, to physically halt that action.

  In times of military emergency, this entire system yielded to a single figure. A Roman Dictator was appointed for a term of six months. Constitutional government dissolved. The Dictator became the absolute master of the state and appointed a Master of the Horse as his most senior lieutenant. Often the Dictator resigned as soon as the crisis was resolved rather than serving the full term. The last ordinary Dictator was appointed in 202 BC. After that date, extreme emergencies were handled through the senatus consultum ultimum, a decree that suspended civil government, declared martial law, and vested the consuls with dictatorial powers.

• 5. The Emperor's Legal Architecture

  ›

  When the empire replaced the republic, the emperor's power was built deliberately on the vocabulary of the old magistracies rather than on open kingship. The two most significant components of an emperor's imperium were the tribunician powers (potestas tribunicia) and the proconsular powers (imperium proconsulare). The tribunician powers gave the emperor authority over Rome's civil government; the proconsular powers gave him authority over the Roman army. These were framed as extensions of existing offices, not as something new.

  By virtue of his proconsular powers, the emperor held the same grade of military command as the consuls and proconsuls under the republic, but without the constitutional restrictions those magistrates had faced. He was eventually given the right to declare war, ratify treaties, and negotiate with foreign leaders, powers that under the republic had belonged to the senate and the assemblies. His proconsular authority gave him command over all of Rome's military governors and thus over most of the army.

  The tribunician powers made the emperor's person sacrosanct, and harming or obstructing him became a capital offense. He gained the authority to preside over and dominate both the assemblies and the senate. He could also perform the duties the republic had assigned to the censors: regulating public morality, conducting a census, and assigning individuals to new social classes, including the senatorial class itself. That last power gave the emperor unchallenged control over senate membership. He was always Pontifex Maximus and a member of each of the four major priesthoods, so religious institutions answered to him as well. During the early empire these constitutional distinctions remained clear, but eventually they eroded, and the emperor's powers became less a legal structure and more a straightforward monarchy.

• 6. Old Offices Under the Empire

  ›

  The traditional magistracies that survived into the empire were the consulship, praetorship, plebeian tribunate, aedileship, quaestorship, and military tribunate. Mark Antony abolished the offices of dictator and Master of the Horse during his consulship in 44 BC. The offices of Interrex and Roman censor were abolished shortly thereafter.

  Under the empire, citizens were divided into three classes, each with its own career path, the cursus honorum. The traditional magistracies were available only to citizens of the senatorial class, though the emperor could allow others to run or appoint them directly. No office lost more power or prestige than the consulship. Its substantive powers had been transferred wholesale to the emperor. Imperial consuls could preside over the senate, act as judges in certain criminal trials, and control public games and shows, but little more.

  The praetors lost a great deal of authority and had little power outside the city. The urban praetor, the chief praetor in Rome, outranked the others, and for a brief period they held authority over the treasury. Plebeian tribunes remained sacrosanct under the empire and in theory retained the power to summon or veto the senate and assemblies. Augustus divided the college of quaestors into two divisions, assigning one to the senatorial provinces and the other to managing civil administration in Rome. Under Augustus, the aediles lost control over the grain supply to a board of commissioners. Once they also lost the power to maintain order in the city, the office became effectively powerless, and it disappeared entirely during the 3rd century.
