This in turn falls into two main periods: first, that of the great Persian empire of the Achaemenid kings (c. 550 BC to c. 330 BC); and second, that of the Parthian and Sasanian empires (c. 140 BC to c. 640 AD). These two periods are punctuated by the Greek-Macedonian occupation of Iran under Alexander the Great and his successors.
