Peace of Antalcidas
After the Peace of Antalcidas in 387 BC, Kaunos again came under Persian rule. During the period that Kaunos was annexed and added to the province of Caria by the Persian rulers, the city was drastically changed. This was particularly the case during the reign of the satrap Mausolos (377–353 BC). The city was enlarged, was modeled with terraces and walled over a huge area. The city gradually got a Greek character, with an agora and temples dedicated to Greek deities. Alexander the Great's 334 BC brought the city under the rule of the Macedonian empire.
