 After having belonged to the kingdom of the Attalids, it became the capital of a district of the province of Asia, except on two occasions during the last century of the Roman Republic when it was temporarily attached to Cilicia.Under Diocletian at the time of the creation of Phrygia Pacatiana, Synnada, at the intersection of two great roads, became the metropolis (capital).In Strabo's time it was still a small town, but when Pliny wrote it was an important place, being the conventus juridicus for the whole of the surrounding country.
