Æ18

Klazomenai, one of the twelve Ionian cities on the Aegean coast of Asia Minor, had an unusually turbulent fourth century — the city was relocated from the mainland to a nearby island (connected by a causeway) partly to escape Persian pressure, a move that shaped its political and economic identity throughout exactly this period. The bronze coinage issued during these decades served local exchange while the city navigated shifting allegiances between Persian satrapal authority and, later, the expanding reach of Macedon.
