How did Alexander the Great defeat the Persian power?

Answer 1

He first won a battle in Asia Minor, and executed the Greek mercenaries in Persia's employ to warn others off this service. This deprived Persia of a source of armoured warriors to match the Macedonian/Greek ones.

He then captured the port cities in the eastern Mediterranean, depriving the Persians of a navy which could attack Greece in Alexander's rear.

He then defeated the Persians in a land battle at Issus which demoralised the Persians and facilitated his destruction of the Persian army at Gaugamela. Darius' demoralised generals assassinated him, hoping to cut a deal with Alexander.

Thereafter coordinated Persian resistance collapsed and he was able to pick off the remaining provinces one at a time.

Answer 2

He had to kill Zraio( king of Persia) Alexander did not do this but captured Zraio's wife and 2 children and held them in a prison. The men on foot had not held their formation because of the swords that were on the wagons so there only hope was with cavalry and they killed 10,000 Persian men and over 5,000 had held or surrendered.

Answer 3

First by invading Asia Minor and defeated the provincial governor at Grannicus, after which he executed the Greek mercenaries to warn Greeks not to join with the Persians, depriving them of that source of heavy infantry to bolster them.

Second he defeated the main Persian army at Issus to give himself freedom of action in the eastern Mediterranean littoral.

Thirdly he took the eastern Mediterran coast to deprive the Persians of a fleet to attack his rear and Greece which was his source of soldiers.

Fourth he defeated the last Persian army in a straight battle at Gaugamela in Mesopotamia.

Fifth he established governance arrangements consolidating his control of the empire.

Answer 4

He first established firm control over the Greek city-states to protect his home base of Macedonia, and be a source of manpower.

He then set about capturing the Mediterranean eastern seaboard to remove the threat of Persian naval invasion of Greece and Macedonia.

He then defeated the Persians in two major battles - Issus and Gaugamela, breaking their unified power.

With coordinated opposition broken, he then defeated the remaining Persian eastern provinces one by one.

Answer 5
