    Athens power gains (Athens lead by strong leader in Pericles)

    Athens gains tremendous power after the was with Persia and begins to make decisions that led to power growth over city states who were not as economically and militarily strong. This does not sit well with Sparta. Building of the "Long Walls" connecting Athens to Piraeus (an valuable harbor city) made it almost impossible for a land army to attach the city of Athens from the Peloponnese Penisula - demonstrating a lack of trust between the Athenians and the Spartans.
