The Romans dallied long in following up the defeat of the Seleucids at Magnesia, when the way lay open to the annexation of Asia Minor, for which its people, torn by their internal wars, would have been even grateful. But it was not until late in the second century b.c. that the west was united as a Roman province. Even then the east remained under the direct government of the local princes, to whom the Roman Senate entrusted their frontier. At the beginning of the first century B.C. the disaffection of Mithridates, king of Pontus, a state bordering the Black Sea, and his efforts to win for himself a kingdom in Cappadocia and Bithynia, was one of the last fitful traces of the old native power, and called up more serious efforts on the part of Rome. The Cilician pirates, who from their base under the southern slopes of Taurus had become a leading naval power, were also suppressed, and during the century that followed the whole country as far as the Euphrates was gradually brought under direct control, and the provincial system was established. The province of _Cilicia_ had been founded in B.C. 103, and after various successive modifications, during which the western district, Cilicia Trachæa, continued to be ruled by the priest-dynasts of Olba, the whole was united with Lycaonia under a consular legate about 137 A.D. _Bithynia-Pontus_, the scene of the late rebellions, came into the power of Rome by the will of its last king in B.C. 74, and the double province was put under the administration of a prætorian proconsul in B.C. 27. _Galatia_ was constituted in B.C. 25, and _Pontus_ was added to it in 63 A.D. Finally, the occupation of _Cappadocia_, dating from A.D. 17, completed the division of the administrative districts; for the sixth province _Asia_, in the west, had been the earliest founded, as we have noted, in B.C. 133.
