 Four months later, Alexander allowed the troops to loot Persepolis, kill all its men and enslave all its women, perhaps as a way to fulfill the expectations of his army and the Greek citizens, or perhaps as a final act of vengeance towards the Persians.This destruction of the city can be viewed as unusual as its inhabitants surrendered without a fight and Alexander had earlier left Persian cities he conquered, such as Susa, relatively untouched.In May 330 BC, Alexander ordered the terrace of Persepolis, including its palaces and royal audience halls, to be burned before he left to find Darius III.
