In 81 BC Lucius Cornelius Sulla added two new praetors so that two proconsuls and six propraetors could be created to govern the ten provinces Rome had acquired by then. The praetors who had previously governed the first four provinces were reassigned to judicial affairs in Rome as the judicial load in the city had increased. Sulla made the governorships annual and required the holder to leave the province within thirty days after the arrival of his successor. In 52 BC Pompey introduced a law which provided that the promagitracies were to be assigned five years after the term of office of the consuls and praetors. Julius Caesar repealed it. Pompey's provision was re-enacted by Augustus.
