Athens over-reached itself in interfering in the affairs of the other Greek city-states, overconfident that its power, war fleet and financial resources could protect it. The Peloponnesian League led by Sparta called its bluff, and Athens lost a destructive 27-year war and was stripped of its empire, becoming thereafter a second rate power.
The turning point in the war was the intervention of Persia, which still had payback to make over its defeat by the Athenian-led Delian League. It provided the Peloponnesian League with the money to build a navy to match the hitherto-unbeatable Athenian navy, and also to pay more than Athens to attract the best warship rowers from Athenian service into the Peloponnesian fleet.

Socrates criticized Athenian leaders because he believed they were corrupt and did not act in the best interest of the people. He felt that their lack of wisdom and virtue contributed to the decline of Athenian society. However, his criticism led to his own downfall as he was ultimately condemned to death by the Athenian authorities.
Athenian greatness stemmed from its democratic governance, cultural achievements, and naval power, which fostered a vibrant society and enabled it to dominate the Delian League. However, this same strength led to hubris, military overreach, and internal strife, particularly during the Peloponnesian War against Sparta. The overextension of resources and the strain on democratic institutions ultimately weakened Athens, contributing to its downfall. Thus, the very qualities that propelled its success also sowed the seeds of its demise.
Both empires grew too large to protect.
