without public office (sine magistratus). This was done because Manlius Acidinus had not been a consul before. As Rome acquired territory, the need for provincial governors grew. The province of Sicily was created in 241 BC, while Corsica and Sardinia was created in 238 BC. In 227 BC, two praetors were assigned the administration of these two provinces. Two more praetors were added when the provinces of Hispania Citerior and Hispania Ulterior were created in 197 BC. After this, no praetors were added even when the number of provinces increased. It became customary to extend the authority of consuls and the praetors at the end of their annual terms. The provinces were assigned by lot to proconsuls and propraetors. The proconsuls were assigned the provinces which contained the larger number of troops. Under Lex Sempronia, enacted in 123 BC, the senate determined the allocation of the provinces before the next consular elections. In 81 BC, Sulla added two praetors so that the two proconsuls and six propraetors could be assigned to govern the ten provinces Rome ruled at that time. Sulla made the governorships annual and required the holder to leave the province within thirty days after the arrival of his successor. In 67 BC, Pompey received extraordinary powers and an unprecedented multiyear proconsulship to deal with the problem of piracy. The "first triumvirate" of Julius Caesar, Pompey and Crassus also received multiyear proconsulships in 59 BC. Marcus Aemilius Lepidus (triumvir) was also granted this power in 38 BC. Roman Empire Under the Republic, consuls and proconsuls had raised and commanded armies loyal to themselves. Augustus, Rome's first emperor, replaced these essentially private armies with a standing imperial army. The consuls and proconsuls lost their military authority, but the titles retained considerable prestige. The provinces were divided between imperial provinces, which were under the jurisdiction of the emperor, and senatorial provinces, which were under the jurisdiction of the senate. The imperial provinces were mostly the border provinces, where most of the legions were stationed. This allowed the emperor to retain control of the army. In the senatorial provinces, the governors were called proconsuls. Tenure was generally restricted to one year. According to Suetonius: Augustus decreed that the governors of the senatorial provinces would receive the title proconsul, regardless of whether they had served as praetor or consul. These were chosen by lot, with the result ratified by the Senate. In
