Answer:
Umm, his name was Alexander the Great
Step-by-step explanation:
There are several reasons why Alexander and his armies were successful in their battles against the Persians. One of the key reasons was the tactical and strategic genius of Alexander himself. He was an incredibly skilled commander who was able to outmaneuver and outthink his opponents on the battlefield.
Another reason for their success was the quality of the soldiers in Alexander's army. They were well trained and disciplined, and they were able to execute complex battle plans with precision.
Additionally, Alexander's army was equipped with the latest weapons and technologies, which gave them an edge over the Persians. They were able to use their superior weaponry and tactics to devastating effect in battle.
Finally, Alexander's campaigns against the Persians were also aided by a number of factors outside of his control. For example, the Persians were weakened by internal conflicts and were unable to mount a unified resistance against Alexander. Additionally, the vast distances involved in the campaigns meant that the Persians were often unable to effectively respond to Alexander's movements.
Overall, Alexander and his armies were successful in their battles against the Persians due to a combination of factors, including the leadership of Alexander, the skill and discipline of his soldiers, and a number of favorable external circumstances.
