Roman magistrate

[6] In theory at least, the tribunician powers (which were similar to those of the plebeian tribunes under the old republic) gave the emperor authority over Rome's civil government, while the proconsular powers (similar to those of military governors, or proconsuls, under the old republic) gave him authority over the Roman army.

While these distinctions were clearly defined during the early empire, eventually they were lost, and the emperor's powers became less constitutional and more monarchical.

When war broke out, he had the sole power to organize and levy troops, to select leaders for the army, and to conduct the campaign as he saw fit.

[2] He controlled all property held by the state, had the sole power to divide land and war spoils, was the chief representative of the city during dealings with either the Gods or leaders of other communities, and could unilaterally decree any new law.

The new king then took the auspices (a ritual search for omens from the Gods), and was vested with legal authority (imperium) by the popular assembly.

After the Dictator was the Consul (the highest position if not an emergency), and then the Praetor, and then the Censor, and then the curule aedile, and finally the quaestor.

The most significant constitutional power that a magistrate could hold was that of "Command" (Imperium), which was held only by consuls and praetors.

[20] Aediles were officers elected to conduct domestic affairs in Rome, and were vested with powers over the markets, and over public games and shows.

Thus, they acted as a popular check over the senate (through their veto powers), and safeguarded the civil liberties of all Roman citizens.

This suspended civil government, declared martial law,[25] and vested the consuls with Dictatorial powers.

[6] In theory at least, the tribunician powers (which were similar to those of the plebeian tribunes under the old republic) gave the emperor authority over Rome's civil government, while the proconsular powers (similar to those of military governors, or Proconsuls, under the old republic) gave him authority over the Roman army.

While these distinctions were clearly defined during the early empire, eventually they were lost, and the emperor's powers became less constitutional and more monarchical.

[7] By virtue of his proconsular powers, the emperor held the same grade of military command authority as did the chief magistrates (the Roman consuls and proconsuls) under the republic.

[27] The emperor's degree of Proconsular power gave him authority over all of Rome's military governors, and thus, over most of the Roman army.

[28] The emperor also had the authority to carry out a range of duties that, under the republic, had been performed by the Roman censors.

Such duties included the authority to regulate public morality (Censorship) and to conduct a census.

Imperial Consuls could preside over the senate, could act as judges in certain criminal trials, and had control over public games and shows.

[33] Under the empire, the plebeian tribunes remained sacrosanct,[34] and, in theory at least, retained the power to summon, or to veto, the senate and the assemblies.

It was not until after they lost the power to maintain order in the city, however, that they truly became powerless, and the office disappeared entirely during the 3rd century.
