Military servicePrior to entering political life and the ''cursus honorum'', a young man of senatorial rank was expected to serve around ten years of military duty. The years of service were intended to be mandatory in order to qualify for political office, but in practice, the rule was not always rigidly applied. The aspiring politician would serve in the Roman cavalry (the '' '') or in the staff of a general who was a relative or a friend of the family. Advancement and honors would improve his political prospects, and a successful military career might culminate in the office of , to which 24 men were elected by the each year. The rank of military tribune is sometimes described as the first office of the ''cursus honorum'', but it was not recognized as such in Roman law and did not carry automatic admittance to the .
QuaestorThe first official post was that of ''quaestor''. Candidates had to be at least 30 years old. However, men of rank could subtract two years from this and other minimum age requirements. Twenty quaestors served in the financial administration at Rome or as second-in-command to a governor in the provinces. They could also serve as the paymaster for a legion. A young man who obtained this job was expected to become a very important official. An additional task of all quaestors was the supervision of public games. As a quaestor, an official was allowed to wear the , but was not escorted by s, nor did he possess .
AedileAt 36 years of age, could stand for election to one of the ''aedile'' (pronounced ''EE-dyle'' /ˈiːdaɪl/, from '' '', "temple edifice") positions. Of these aediles, two were plebeian and two were patrician, with the patrician aediles called Curule Aediles. The plebeian aediles were elected by the and the curule aediles were either elected by the or appointed by the reigning consul. The aediles had administrative responsibilities in Rome. They had to take care of the temples (whence their title, from the Latin '' '', " "), organize games, and be responsible for the maintenance of the public buildings in Rome. Moreover, they took charge of Rome's water and food supplies; in their capacity as market superintendents, they served sometimes as judges in mercantile affairs. The Aedile was the supervisor of public works; the words "edifice" and "edification" stem from the same root. He oversaw the public works, temples and markets. Therefore, the Aediles would have been in some cooperation with the current , who had similar or related duties. Also they oversaw the organization of festivals and games (''ludi''), which made this a very sought-after office for a career minded politician of the late republic, as it was a good means of gaining popularity by staging spectacles. Curule Aediles were added at a later date in the 4th century BC, and their duties do not differ substantially from plebeian aediles. However, unlike plebeian aediles, curule aediles were allowed certain symbols of rank—the '' '' or 'curule chair,' for example—and only patricians could stand for election to curule aedile. This later changed, and both Plebeians and Patricians could stand for Curule Aedileship. The elections for Curule Aedile were at first alternated between Patricians and Plebeians, until late in the 2nd century BC, when the practice was abandoned and both classes became free to run during all years. While part of the ''cursus honorum'', this step was optional and not required to hold future offices. Though the office was usually held after the ship and before the ship, there are some cases with former praetors serving as aediles.
PraetorAfter serving either as quaestor or as aedile, a man of 39 years could run for ''praetor''. The number of praetors elected varied through history, generally increasing with time. During the republic, six or eight were generally elected each year to serve judicial functions throughout Rome and other governmental responsibilities. In the absence of the consuls, a praetor would be given command of the garrison in Rome or in Italy. Also, a praetor could exercise the functions of the consuls throughout Rome, but their main function was that of a judge. They would preside over trials involving criminal acts, grant court orders and validate "illegal" acts as acts of administering justice. A praetor was escorted by six lictors, and wielded '' ''. After a term as praetor, the magistrate would serve as a provincial governor with the title of propraetor, wielding propraetor imperium, commanding the province's legions, and possessing ultimate authority within his province(s). Two of the praetors were more prestigious than the others. The first was the Praetor Peregrinus, who was the chief judge in trials involving one or more foreigners. The other was the Praetor Urbanus, the chief judicial office in Rome. He had the power to overturn any verdict by any other courts, and served as judge in cases involving criminal charges against provincial governors. The Praetor Urbanus was not allowed to leave the city for more than ten days. If one of these two Praetors was absent from Rome, the other would perform the duties of both.
ConsulThe office of ''consul'' was the most prestigious of all of the offices on the cursus honorum, and represented the summit of a successful career. The minimum age was 42. Years were identified by the names of the two consuls elected for a particular year; for instance, ''M. Messalla et M. Pisone consulibus'', "in the consulship of Messalla and Piso," dates an event to 61 BC. Consuls were responsible for the city's political agenda, commanded large-scale armies and controlled important provinces. The consuls served for only a year (a restriction intended to limit the amassing of power by individuals) and could only rule when they agreed, because each consul could the other's decision. The consuls would alternate monthly as the chairman of the Senate. They also were the supreme commanders in the Roman army, with each being granted two legions during their consular year. Consuls also exercised the highest juridical power in the Republic, being the only office with the power to override the decisions of the Praetor Urbanus. Only laws and the decrees of the Senate or the People's assembly limited their powers, and only the veto of a fellow consul or a tribune of the plebs could supersede their decisions. A consul was escorted by twelve lictors, held imperium and wore the toga praetexta. Because the consul was the highest executive office within the Republic, they had the power to veto any action or proposal by any other magistrate, save that of the Tribune of the Plebs. After a consulship, a consul was assigned one of the more important provinces and acted as the governor in the same way that a did, only owning Proconsular imperium. A second consulship could only be attempted after an interval of 10 years to prevent one man holding too much power.
GovernorAlthough not part of the Cursus Honorum, upon completing a term as either Praetor or Consul, an officer was required to serve a term as Propraetor and Proconsul, respectively, in one of Rome's many . These Propraetors and Proconsuls held near autocratic authority within their selected province or provinces. Because each governor held equal imperium to the equivalent magistrate, they were escorted by the same number of lictors (12) and could only be vetoed by a reigning Consul or Praetor. Their abilities to govern were only limited by the decrees of the Senate or the people's assemblies, and the was unable to veto their acts as long as the governor remained at least a mile outside of Rome.
CensorAfter a term as consul, the final step in the Cursus Honorum was the office of ''censor''. This was the only office in the Roman Republic whose term was a period of eighteen months instead of the usual twelve. Censors were elected every five years and although the office held no military imperium, it was considered a great honour. The censors took a regular census of the people and then apportioned the citizens into voting classes on the basis of income and tribal affiliation. The censors enrolled new citizens in tribes and voting classes as well. The censors were also in charge of the membership roll of the Senate, every five years adding new senators who had been elected to the requisite offices. Censors could also remove unworthy members from the Senate. This ability was lost during the dictatorship of Sulla. Censors were also responsible for construction of public buildings and the moral status of the city. Censors also had financial duties, in that they had to put out to tender projects that were to be financed by the state. Also, the censors were in charge of the leasing out of conquered land for public use and auction. Though this office owned no imperium, meaning no lictors for protection, they were allowed to wear the '' ''.
Tribune of the PlebsThe office of was an important step in the political career of . Patricians could not hold the office. The Tribune was an office first created to protect the right of the common man in Roman politics and served as the head of the . In the mid-to-late Republic, however, plebeians were often just as, and sometimes more, wealthy and powerful than patricians. Those who held the office were granted (the right to be legally protected from any physical harm), the power to rescue any plebeian from the hands of a patrician magistrate, and the right to veto any act or proposal of any magistrate, including another tribune of the people and the consuls. The tribune also had the power to exercise capital punishment against any person who interfered in the performance of his duties. The tribunes could even convene a Senate meeting and lay legislation before it and arrest magistrates. Their houses had to remain open for visitors even during the night, and they were not allowed to be more than a day's journey from Rome. Due to their unique power of sacrosanctity, the Tribune had no need for lictors for protection and owned no imperium, nor could they wear the toga praetexta. For a period after Sulla's reforms, a person who had held the office of Tribune of the Plebs could no longer qualify for any other office, and the powers of the tribunes were more limited, but these restrictions were subsequently lifted.
Princeps senatusAnother office not officially a step in the ''cursus honorum'' was the ''princeps senatus'', an extremely prestigious office for a patrician. The ''princeps senatus'' served as the leader of the Senate and was chosen to serve a five-year term by each pair of Censors every five years. Censors could, however, confirm a ''princeps senatus'' for a period of another five years. The ''princeps senatus'' was chosen from all Patricians who had served as a Consul, with former Censors usually holding the office. The office originally granted the holder the ability to speak first at session on the topic presented by the presiding magistrate, but eventually gained the power to open and close the senate sessions, decide the agenda, decide where the session should take place, impose order and other rules of the session, meet in the name of the senate with embassies of foreign countries, and write in the name of the senate letters and dispatches. This office, like the Tribune, did not own ''imperium'', was not escorted by lictors, and could not wear the ''toga praetexta''.
Dictator and magister equitumOf all the offices within the Roman Republic, none granted as much power and authority as the position of ''dictator'', known as the Master of the People. In times of emergency, the Senate would declare that a dictator was required, and the current consuls would appoint a dictator. This was the only decision that could not be vetoed by the Tribune of the Plebs. The dictator was the sole exception to the Roman legal principles of having multiple magistrates in the same office and being legally able to be held to answer for actions in office. Essentially by definition, only one dictator could serve at a time, and no dictator could ever be held legally responsible for any action during his time in office for any reason. The dictator was the highest magistrate in degree of imperium and was attended by twenty-four lictors (as were the former Kings of Rome). Although his term lasted only six months instead of twelve (except for the Dictatorships of Sulla and ), all other magistrates reported to the dictator (except for the tribunes of the plebs - although they could not veto any of the dictator's acts), granting the dictator absolute authority in both civil and military matters throughout the Republic. The Dictator was free from the control of the Senate in all that he did, could execute anyone without a trial for any reason, and could ignore any law in the performance of his duties. The Dictator was the sole magistrate under the Republic that was truly independent in discharging his duties. All of the other offices were extensions of the Senate's executive authority and thus answerable to the Senate. Since the Dictator exercised his own authority, he did not suffer this limitation, which was the cornerstone of the office's power. When a Dictator entered office, he appointed to serve as his second-in-command a ''magister equitum'', the Master of the Horse, whose office ceased to exist once the Dictator left office. The magister equitum held Praetorian imperium, was attended by six lictors, and was charged with assisting the Dictator in managing the State. When the Dictator was away from Rome, the magister equitum usually remained behind to administer the city. The magister equitum, like the Dictator, had unchallengeable authority in all civil and military affairs, with his decisions only being overturned by the Dictator himself. The Dictatorship was definitively abolished in 44 BC after the assassination of Gaius Julius Caesar ( ).
