Republican A second praetorship was created around 241 BC, more clearly separating this office from that of the consulship. There were two reasons for this: to relieve the weight of judicial business and to give the Republic a
magistrate with
imperium who could field an army in an emergency when both
consuls were fighting a far-off war.
Praetor peregrinus By the end of the
First Punic War, a fourth magistrate entitled to hold
imperium appears, the
praetor qui inter peregrinos ius dicit ("the praetor who administers justice among foreigners"). Although in the later Empire the office was titled
praetor inter cives et peregrinos ("among citizens and foreigners", that is, having jurisdiction in disputes between citizens and noncitizens), by the time of the 3rd century BC, Rome's territorial annexations and foreign populations were unlikely to require a new office dedicated solely to this task.
T. Corey Brennan, in his two-volume study of the praetorship, argues that during the military crisis of the 240s the second praetorship was created to make another holder of
imperium available for command and provincial administration
inter peregrinos. During the
Hannibalic War, the
praetor peregrinus was frequently absent from Rome on special missions. The urban praetor more often remained in the city to administer the judicial system.
Praetor urbanus The
praetor urbanus presided in civil cases between citizens. The Senate required that some senior officer remain in Rome at all times. This duty now fell to the
praetor urbanus. In the absence of the consuls, he was the senior magistrate of the city, with the power to summon the Senate and to organize the defense of the city in the event of an attack. He was not allowed to leave the city for more than ten days at a time. He was therefore given appropriate duties in Rome. He superintended the
Ludi Apollinares and was also the chief magistrate for the administration of justice and promulgated the
Praetor's Edict. These Edicts were statements of praetor's policy as to judicial decisions to be made during his term of office. The praetor had substantial discretion regarding his Edict, but could not legislate. In a sense the continuing Edicts came to form a corpus of precedents. The development and improvement of
Roman Law owes much to the wise use of this praetorial discretion.
Additional praetors The expansion of Roman authority over other lands required the addition of praetors. Two were created in 227 BC, for the administration of
Sicily and
Sardinia, and two more when the two
Hispanic provinces were formed in 197 BC. The dictator
Lucius Cornelius Sulla transferred administration of the provinces to
former consuls and praetors, simultaneously increasing the number of praetors elected each year to eight, as part of his
constitutional reforms.
Julius Caesar raised the number to ten, then fourteen, and finally to sixteen.
Imperial Augustus made changes that were designed to reduce the Praetor to being an imperial administrator rather than a magistrate. The electoral body was changed to the Senate, which was now an instrument of imperial ratification. To take a very simplistic view, the establishment of the principate can be seen as the restoration of monarchy under another name. The Emperor therefore assumed the powers once held by the kings, but he used the apparatus of the republic to exercise them. For example, the emperor presided over the highest courts of appeal. The need for administrators remained just as acute. After several changes, Augustus fixed the number at twelve. Under
Tiberius, there were sixteen. As imperial administrators, their duties extended to matters that the republic would have considered
minima. Two praetors were appointed by
Claudius for matters relating to
Fideicommissa (
trusts), when the business in that department of the law had become considerable, but
Titus reduced the number to one; and
Nerva added a Praetor for the decision of matters between the
fiscus (
treasury) and individuals.
Marcus Aurelius appointed a Praetor for matters relating to
tutela (
guardianship). ==Praetors as judges==
