CEVAP:

After the Greek conquest of the Achaemenid Empire, there was a brief period of chaos followed by the Parthian Empire. The Parthian Empire lasted from 247 BCE to 224 CE. Greek culture, installed in Persia after Alexander’s conquest, continued to play an important role in politics and commerce. This influence was passed on from the Parthian Empire to the Sasanian Empire, which ruled Persia from 224 CE to 651 CE. By 620 CE, the Sasanian Empire were like the final days of the First Persian Empire when Alexander the Great was about to conquer it.
