The burning of persepolis was revenge of what?

The burning of Persepolis in 330 BCE was largely seen as an act of revenge by Alexander the great for the destruction of Athens and other Greek cities by the Persian Empire during the Greco-Persian Wars. After defeating Darius III, Alexander ordered the burning of the ceremonial capital to symbolize the defeat of Persia and to demonstrate his power. This act also had a political motive, as it aimed to send a message to other cities about the consequences of opposing him. The destruction marked a significant moment in the culmination of the long-standing conflict between Greece and Persia.
