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.
The city-states of Athens and Sparta joined forces along with the other southern Greek city-states to defeat the Persian invasion in 480-479 BCE, however they were not enemies - they were allies before and after the Persian invasion. Sparta had offered support to Athens against the Persian attack on Athens a decade before that, and Athens supported the Spartans when Messenia revolted against Spartan rule twenty years after the Persian invasion. Not exactly enemies. They became enemies when Athens set out to dominate the Greek world, resulting in the Spartan-led Peloponnesian League and Athens and its new empire clashed in a destructive Peloponnesian War 431-404 BCE. Athens lost, was stripped of its empire and became a second rate power.
The naval Battle of Salamis won a victory for the Greek allies, primarily Athens. It, in effect, stranded the Persian Army in Greece, forcing it to make a fighting retreat home, leading to its defeat at Plataea. After the war, Athens formed a naval defense league to prevent any further Persian incursions. Athens became he leading cultural center of its time, leading the world in architecture, sculpture, and theater. In time, Athens began to use the treasury of the league as its personal resource, and behaved as an imperial power, bringing it into conflict with its former ally, Sparta, and sparking the Peloponnesian War, which eventually led to Athens' defeat and the fall of democracy in Ancient Greece.
After peace was agreed, Athens was able to convert the Delian League which it had led, into an Empire of its own, and brought on the 27-year Peloponnesian War which devastated the Greek world.

The Persians were defeated by ALLIED army of GREEKS, with navy lead by Athens and ground forces by Sparta. In first invasion Persians were defeated by only Athens and her allies.
After peace was made between the Persian Empire and the Delian League led by Athens, Athens converted the League into an empire of its own, continuing to tax the cities of the League and spending the proceeds on itself - beautifying the city, putting half its own population on the public payroll, and maintaining a war fleet to dominate the Greek world and to collect the annual taxes from the Greek cities.

They provided the impetus to form an anti-Persian alliance headed by Athens. When peace was made with Persia after 50 years of intermittent fighting, Athens converted this league into an empire of its own, and its expansionary tendencies brought it into confrontation with the Peloponnesian League, resulting in the 27-year Peloponnesian War which devastated the Greek world from Sicily to Asia Minor.
It put an end to Persian expansion to the west and led to the contest for power in the Greek world between Athens and its empire and the Spartan-led Peloponnesian League.
Ionia - the Greco-Persian Wars was a result of the Ionian revolt .The wars began when the Greek city-states in Asia Minor revolted against Persian rule. Athens interfered, bringing Persian reprisal, which widened the conflict to the rest of the Greek world.
If you mean Sparta and Athens, they were not rivals but supported each other. The rivalry came after the Persian invasion was repelled and Athens turned the Delian League it had led against the Persian Empire into an empire of its own and used its resources to try to dominate the Greek world.
The Greek city-states in Asia Minor were freed from Persian Empire rule and hoped for peace and independence, only to be swallowed up into an Athenian empire and plunged into the Peloponnesian War.

There were three kings of Persia called Darius in the 6th, 5th and 4th Centuries BCE. Greece was not a unified country - the Greek world was comprised of 2,000 independent city-states, including Sparta, Thebes, Corinth, Athens. So there was no capital of the Greek world.
