Galatia

A Celtic territory in the highlands of central Anatolia settled by migrating Gauls in 278 BCE, organized as a tetrarchy of three tribes (Tectosages, Trocmii, Tolistobogii) and tamed as a Roman client state after Attalid and Roman military campaigns.

After the death of King Amyntas in 25 BCE, Augustus incorporated Galatia as a Roman province; Ancyra became the provincial capital.
