Alexander the Great in a short period of time was able to build a huge empire on the remains of the great Persian. To a large extent, he succeeded in uniting the barbarians and the Hellenes. Although most likely he managed to combine the Persian culture with the Greek. True, to a greater extent this result of this process was noticeable on the territory of Alexander’s Asian possessions.
