History
In the 1st century AD Vespasian combined several provinces, including Cappadocia, to create one large province with its eastern boundary marked by the Euphrates River. This province once again splintered during Trajan's reign - the newly created province of Cappadocia, bounded by the Euphrates to the East, included Pontus and Lesser Armenia. The Halys River became an interior river and never regained its significance as a political border. In the 130s a governor of Cappadocia wrote: "long ago the Halys River was the boundary between the kingdom of Croesus and the Persian Empire; now it flows under Roman dominion."
