Delian league
Athens was a polis. It didn't contain other poleis (plural of polis), though in the Delic-Attic League they did dominate many others.
Athens converted the Delian League into an empire of its own, and used the forces and money to attempt to dominate the Greek world.
Athens ruled the Delian League.
Athens converted its anti-Persian confederation into and empire, and used this power to try to dominate the rest of the Greek cities, many of which were members of the Peloponnesian League and opposed this. Athens' continuing aggressivenss forced the declaration of war in 431 BCE which turned into a 27-year war which devastated Greece. The ultimate trigger was Athens' attempt to bankrupt its neighbour Megara by stopping its trade with Athens' empire. Megara was a member of the Peloponnesian League and appealed to it for support. The League urged Athens to desist. Sparta, as leader of the League was pressured by it to take action: it appealed to Athens to compromise; Athens, over-confident of its strength held out, and war ensued.
Sparta led the Peloponnesian League . Athens led the Delian League .
After the persian wars, athens used the anti-Persian league to further its own interests, interfering in the affairs of other Greek cities. A Peloponnesian Leage was formed to oppose it. Athens persisted in trying to dominate, the Peloponnesians resisted, and war ensued.
Yes, because Sparta and Athens were once allies but then Athens turned on Sparta and Sparta responded with war.

Athens
The Delian League significantly strengthened Athens politically and economically after the Persian Wars, as it allowed the city-state to dominate its allies and collect tribute. This wealth funded the construction of impressive structures like the Parthenon and bolstered its naval power, establishing Athens as a leading force in the Greek world. However, the League's transformation into an Athenian empire also fostered resentment among member states, contributing to tensions that eventually led to the Peloponnesian War. Ultimately, while the League enhanced Athens' influence, it also sowed the seeds of conflict and division within Greece.
Athens had headed the Delian League which protected the eastern Greek cities from Persian dominance. When Persia withdrew, Athens turned the league into an empire, and used this power to interfere in the affairs of other Greek cities. This led the cities of the Peloponnesian League to appeal to Sparta to lead action to limit Athens' power. Athens refused compromise and a destructive 27 year war ensued, which the Athenians lost, and were stripped of their empire, reducing them to a second rate power which could no longer try to dominate Greece and live high on the proceeds.
