Look for:
Trojan War - western Turkey
Peloponnesian War - Greece, Sicily and Eastern Mediterranean.
Persian War - the Aegean Sea littoral.
Alexander's conquest.
Were you talking about the Greek Persian and Peloponnesian Wars? If so, the Persian war was between the invading Persians and the defending Greeks, who formed a league in which the military was led by one of the Spartan kings. (Sparta had two kings at the same time.) In the Peloponnesian War, it was the Delian League (Athens and allies) vs. the Peloponnesian League (Sparta and allies) Sparta ended up beating Athens after destroying their fleet.
Trojan War 12th Century BCE, Peloponnesian War 5th Century BCE.
why is the Trojan war and the Persian war different
There is nothing to compare. The so-alled Trojan war was an extended looting of the coast and islands of western Asia Minor by the Greeks. The Peloponnesian War was a struggle within the Greek world between the Athenian empire and the Peloponnesian League over the former's attempts at dominance.
No.
People died needlessly and places were devastated, pursuing the interests of specific aristocratic leaders. The Trojan War was in reality a looting expedition by the Achaeans (Greeks) who pillaged western Asia Minor and the Islands for a decade. The Achaean aristocracy got most of the loot and enslaved people and Asia Minor was devastated. The Persian War was an attempt by the Persian Empire to impose peace on the Eastern Mediterranean under it's overall control, but ended up as achieving nothing but 50 years of war, but also allowed Athens to make an empire of it's own by seizing control of the cities it had allied against the Persian Empire. The Peloponnesian War flowed from from Athens' grab for empire, as this success led it to try to dominate the other Greek cities outside its empire. When this was resisted by the Peloponnesian League, a 27 year-war followed which devastated the Greek world.
None - different eras, different peoples, different motivations.
No, it was about the Persian War 700 years later.
It tells about the battles and hero conflicts of the Greek-Trojan War.
That refers to how in the Peloponnesian war that was a riddle an oracle predicted. What began with an apple (the golden apple at the wedding that had inscribed "to the most beautiful" on it that led to the beginning of the Peloponnesian War, ended with a horse (the Trojan Horse that sacked Troy after it was brought inside the Trojan walls with the Greek warriors inside.
