First, in 498 BCE during the Ionian Revolt of cities within the Persian Empire, Athens sent across a force which became involved in the burning of the Persian provincial capital of Sardis, which attracted a Persian punitive expedition against it in 490 BCE, repelled at Marathon.
Athens was an early target in the Persian invasion of peninsular Greece a decade later. Exposed to immediate attack, it sent its population to refuge in the Peloponnesian cities and embarked its forces into its ships and fought at sea at Artemesion and Salamis. When the sea war was won, its soldiers joined the land forces for the land battles the following year at Plataia and Mykale.
After the invasion was repelled, Athens led the Delian League to harrass the Persians in Asia Minor and the Islands, for thirty years.
Callias, an Athenian negotiated a peace in 449 BCE which gave portection to the Greek city-states in the Eastern Mediterranean.
In the Persian War it intervened in the Ionian Revolt, burning down the provincial capital of Sardis and so drawing Persian attention on the Greek city-states of mainland Greece which were outside the Persian Empire.
Persia then sent a punitive expedition against Eretria and Athens in retaliation; Athens defeated it at Marathon.
Persia then mounted a full scale invasion of mainland Greece in which Athens was part of the defensive force which was defeated at Artemesion, then repelled the Persians at Salamis, Plataia and Mykale.
Athens then led the Delian of a couple of hundred city-states around the Aegean Sea, which defeated the Persians at several battles, most decisively at Eurymedon and Cyprus, at which stage Persia gave up trying to impose peace on the Greeks and left them to their usual fighting amongst themselves.
Athens then converted the anti-Persian league into an empire of its own and for a period lived well on the proceeds. By using part of the proceeds to maintain a strong fleet, it converted the league into an empire of its own, and used the power to meddle in the affairs of cities outside its empire. This brought it into confrontation with the Spartan-led Peloponnesian League, and the ensuing 27-year war devastated the Greek world.
Athens eventually lost, after Persia intervened on the side of the Peloponnesians, and was stripped of its empire, becoming thereafter a second rate power, and no longer able to afford the high lifestyle which its empire had provided for it.
Athens converted the Delian League which it had led in the later phase of the war with the Persian Empire into an empire of its own, and after peace with the Persians it used this power to interfere in the rest of the Greek world, resulting in the devastating 27-year Peloponnesian War.
because the gods were really mad at the people from Sparta that they decided to kill them all....so the Athens wins
Wars don't have roles. They happen and have outcomes. The Peloponnesian War was between the Athenian empire and the Peloponnesian League, which Athens lost and lost its empire.
It varied from early friendship, to opponent in the Persian invasion of Greece 480-479 BCE, to friendship when Persia financed the overthrow of Athens in the Peloponnesian War, to enmity when Spartan King Agesilaus invaded Persian Asia Minor 396-394 BCE .... and so on.

Athens was the maritime power and Sparta was the continental power. The war slogged on and off for over thirty years until Sparta finally gained superiority at sea, and a plague brought in form the Pontic grain ships killed possibly as many as one-third of the population of Athens, leaving it, almost literally, too weak to fight.
Persia sent a punitive expedition against Eretria and Athens for their role in supporting the Ionian revolt against Persian rule. Eretria was captured but Athens resisted and defeated the Persian force on the plain of Marathon.
A trireme was an ancient vessel especially used by Phoenicians, Greeks and Romans. Triremes played an important role in the Persian Wars and Peloponnesian War.
Persia sent a punitive expedition against Eretria and Athens for their role in supporting the Ionian Revolt against Persian rule in Asia Minor. Eretria was captured but Athens resisted and defeated the Persian force on the plain of Marathon.
It was the Ionian revolt against Persian rule that expanded into the Persian War 449-449 BCE.
It was until it struck a rich lode of silver and developed the strongest Greek war fleet, when it assumed a leading role against the Persian Empire, and after it were repulsed, converted the anti-Persian alliance into an empire of its own. It used this power too crudely and lost heavily in a war with the southern Greek Peloponnesian League and also lost its empire and the money it brought in, slipping back to relative unimportance as a second rate power.
