Coins from Carian Satrapy
Caria was then incorporated into the Persian Achaemenid Empire as a satrapy (province) in 545 BC. The most important town was Halicarnassus, from where its sovereigns, the tyrants of the Lygdamid dynasty (c.520-450 BC), reigned. After the unsuccessful Persian invasion of Greece the cities of Caria became members of the Delian League. The Hecatomnid dynasty ruled Caria and surrounding areas about 395–334 BCE, after Caria had left the Delian League and returned under the control of the Achaemenid Empire.

The Hecatomnids were nominally satraps (governors) under the Persian Achaeminid Empire, but ruled with considerable autonomy, and established a hereditary dynasty. The dynasty was founded by Hecatomnus and originally had its seat in Mylasa; Mausolus moved it to Halicarnassus.
