They each provided major forces for a coalition of southern Greek city-states to resist the Persian invasion. After the invasion was repelled, Sparta left the follow-up action to Athens. They remained allies until Athens converted the anti-Persian alliance into an empire of its own after the Persians gave up trying to enforce peace in the western Mediterranean. Athens over-reached itself and this led to the Peloponnesian War between a Spartan alliance and Athens and its empire.
In this war Persia gave assistance to Sparta to help it defeat Athens.
Yes. They joined forces to defeat their common enemy Greece's common enemy, the Persians. But when they weren't on the defensive, they usually were against each other.

No city won. The Sparta alliance with Persian backing defeated the Athens alliance or empire.
The war between Athens and Sparta was the Peloponnesian War. the ancient Greeks called it the war between Athens and its allies and Sparta and its allies. The word Peloponnesian was used because the alliance led by Sparta against the Athenian empire was the Peloponnesian alliance, as most of the cities were in the Peloponnese Peninsula.
On one side, Athens. On the other, Sparta.
It was a war between Athens and its allies and Sparta and its allies - the latter tried to control the expansionary efforts of the Athenian empire. It lasted from 431 BCE to 404 BCE, when Persian financial intervention swung the war in favour of the Spartan alliance, resulting in the capture of Athens.
Athens was part of an alliance of Greek city-states which varied in size from a couple of dozen to 180, led at first by Sparta, then later by Athens after defeat of the Persian invasion.
Athens and Sparta were friendly before the Persian War. They naturally joined the alliance which repelled the Persian invasion. A Spartan force helped Athens retain its government against a revolt pre-war. Athens post-war helped Sparta put down a serf rebellion, but then started to side with the serfs, so the Spartans sent them home. That was the split.
