Although the defeat at Gaugamela marked the end of the Persian Empire and with it the Archaemenid dynasty, major elements of the empire continued to function. Some of the ways the Persian Empire lived on politically where.
- Alexander married two Persian princesses in a symbolic gesture to unite the Macedonian and Persian cultures.
- He also encouraged all his generals and noblemen to take Persian brides
- Alexander also made a concerted effort to incorporate Persian customs, officials and military formations into his growing army.
- The Macedonian empire also briefly adopted the satrap system of governance (which is originally Persian) after the death of Alexander the great.
- One of Alexander’s generals would eventually come to rule what can be thought of as the political successor to the Archaemenid Empire, in the form of the Seleucid Empire.
