The former province of Asia, which embraced Mysia, Lydia, Phrygia, and Caria, was converted from a frontier province into a central one.

The newly-erected provinces were, that of Bithynia and Pontus, which was formed out of the whole former kingdom of Nicomedes and the western half of the former Pontic state as far as and beyond the Halys; that of Cilicia, which indeed was older, but was now for the first time enlarged and organized in a manner befitting its name, and comprehended also Pamphylia and Isauria; that of Syria, and that of Crete.

Much was no doubt wanting to render that mass of countries capable of being regarded as the territorial possession of Rome in the modern sense of the term.

The form and order of the government remained substantially as they were; only the Roman community came in place of the former monarchs.

Those Asiatic provinces consisted as formerly of a motley mixture of domanial possessions, urban territories de facto or de jure autonomous, lordships pertaining to princes and priests, and kingdoms, all of which were as regards internal administration more or less left to themselves, and in other respects were dependent, sometimes in milder sometimes in stricter forms, on the Roman government and its proconsuls very much as formerly on the great-king and his satraps.
Feudatory Kings Cappadocia Commagene Galatia The first place, in rank at least, among the dependent dynasts was held by the king of Cappadocia, whose territory Lucullus had already enlarged by investing him with the province of Melitene (about Malatia) as far as the Euphrates, and to whom Pompeius farther granted on the western frontier some districts taken off Cilicia from Castabala as far as Derbe near Iconium, and on the eastern frontier the province of Sophene situated on the left bank of the Euphrates opposite Melitene and at first destined for the Armenian prince Tigranes; so that the most important passage of the Euphrates thus came wholly into the power of the Cappadocian prince.
