After the defeat of the Persian invasion in 480-479 BCE, Sparta wanted to repatriate all Greeks in Asia to mainland Greece to end the problem with Persia (this actually happened in 1923 CE, after World War 1 - foresight indeed!). Athens proposed an aggressive alliance against Persia, which as the dominant maritime power it had to lead.
Sparta had no interest in overseas adventurism, and readily ceded that leadership to Athens, which apportioned contributions to the alliance cities. Some met this in ships, most paid their way out of this, though some reneged and Athens collected the contributions by force. With only the islands Samos, Lesbos and Chios contributing ships, Athens had an overwhelming superiority in amphibious power, and the money to pay for it. This anti-Persian league then progressively became effectively an Empire of Athens.
A definite transition took place when the league defeated Persia in two sea and land battle at the Eurymedon River and Cyprus, resulting in a peace of 449 BCE which restricted Persian vessels from moving into Greek-controlled waters or interfering in Greek cities; the real reason for the league ceased to exist. For 'security' the treasury was moved from neutral Delos to Athens, and under Pericles' guiding hand this was squandered on beautification of Athens, keeping half of its citizens in public employment, and 100 ships in service enforcing collection of league (empire) membership dues. In addition Athens went to lengths to establish sympathetic radical democracies in league cities. As a side ethnic issue, the core of the Spartan alliance (Peloponnesian League) were Dorian Greeks of the Peloponnese peninsula; the Athenian empire comprised mainly the Ionian Greeks of Asia Minor and the Islands.
This polarisation of the reclusive Spartans and the adventurous Athenians spilt over when their respective allies clashed with each other - notably the Corcyra and Potidaia disputes with Corinth, and then Athens' trading ban on the Peloponnesian city of Megara. The series of clashes put allied pressure on Sparta to act, and after much foot dragging and with much trepidation it issued an ultimatum to Athens, which rejected it.
Athens was confident that the combination of its walls and amphibious power was more than a match for the largely land-bound Spartan alliance, and it rejected negotiation, preferring to maintain its naval dominance, and challenge Spartan league land dominance.
Neither side foresaw 27 years of warfare which devastated so much of the Greek world from Sicily to Asia, and coincidentally led to Persian influence in Greek affairs, and eventually Macedonian dominance.

There were many Greek wars - what period did you have in mind? You could always try 'The Causes of the Peloponnesian War'.
This question is incoherent. If you want an answer rewrite it so that it is clear what you are talking about.
