Answer:
Persians
Step-by-step explanation:
The classical period of Greek art and architecture ended when the war began between Alexander the Great and Persians. Alexander the Great fought three battles which included the battle of Granicus, Issus, and Gaugamela. The final victory forced the Persian troops to withdraw and give more time for Alexander to proceed further into Persian territory which helped him to enter into the land of the northwestern Indus valley.
