The king of Galatia ruled the more easterly section of Phrygia, and it eventually formed a part of the Roman province of Galatia. This eastern section is sometimes termed Galatian Phrygia; it was N of Pisidia and NW of Lycaonia.

In the first century “Phrygia” was an inland area in the Roman provinces of Galatia and Asia, covering the plateau country N of the Taurus Range, from the Halys River on the E to the upper valleys of the Hermus and Maeander rivers on the W.
