How did Alexander rule Persia?

Alexander the great ruled Persia after conquering the Achaemenid Empire in a series of battles, most notably the Battle of Gaugamela in 331 BCE. He adopted a policy of integration, respecting local customs and traditions while establishing a system of satrapies (provinces) to maintain control. Alexander encouraged intermarriage between his soldiers and Persian women, and he embraced Persian dress and customs to legitimize his rule. His approach helped stabilize his empire, although it also faced resistance from some Persian nobles.
