The Achaemenids conquered Anatolia in the sixth century bce. However, in contrast to the historical descriptions of political response to Achaemenid control, e.g. the so-called 'Ionian revolt' of east Greek territories in Western Anatolia, the operation of Achaemenid-period economies in this region remains obscure. Only a handful of occupation sites in western Turkey provide archaeological data contemporary with Achaemenid rule. In this paper, we compare the results of compositional analysis on Achaemenid-period ceramics from a provincial centre, Seyitömer, with comparable analyses from similar periods at Sardis and Gordion. During the period of Achaemenid control a comparatively high level of compositional and typological diversity at this provincial centre suggests a surprising increase in regional connectivity, both locally and with East Greek and Greek centres.
