Compare the military powers of the Persians and Macedonians in terms of armament, methods of control (subordination), vastness of territory and time of existence.
The Persian Empire did not include only the territory of Greece, the Persian Empire existed for more than two centuries, the Empire created by Alexander collapsed after his death. The Persians completely subjugated the conquered peoples. Alexander pursued a policy of “fusion of peoples”, attracted the nobility of the conquered territories to government, considered himself the heir to the Persian rulers. Alexander’s army outnumbered the Persian forces in its training and weapons; had a phalanx, cavalry and mercenary and engineering troops. The Persian army was divided into infantry and cavalry, there was a fleet; the army included representatives of many peoples conquered by the Persians.
The Persian empire lasted longer, but it also grew with new territories longer than the state of the Macedonians. Therefore, Alexander needed people to run the state, for which the local nobility was involved. He simply would not have enough funds and strength to manage vast territories using the methods of the Persians.
