The fundamental cause of the Peloponnesian War was Sparta's dear and jealousy of the power and wealth of Athens. This caused Sparta to push many city-states to turn against Athens, as well as some citizens of Athens to turn against their own city-state. The Peloponnesian War was fought in three stages or phases as historians like to call them and took place from 431-404 BC.
