Even though the war was over, relations between Athens and Sparta continued to sour. Athens continued to grow in power and began to pose a threat to Sparta and the Peloponnesian League. During the “Thirty Years' Peace” a series of conflicts occurred that pushed Sparta and Athens back into war. For example, Athens intervened in a dispute between a colony and a city-state during the Corinth-Corcyra War. Corcyra (the city-state) was supported by Athens, while Epidamnos (the colony) was supported by Corinth. This persisted for a few years until the Corinthians abandoned their campaign, but this would not be the last time Athens clashed with Corinth. Not long after, a Corinthian colony called Potidaea rebelled against its rulers. Athens was interested in intervening, but the Spartans immediately took Potidea's side. Sparta threatened to invade Attica (the area where Athens is located) if Athens decided to attack Potidaea. Athens would not have been threatened by this, and war would have begun to become inevitable. Ignoring the fact that Potidaea was officially protected by Sparta, Athens proceeded to besiege Potidaea. This move was motivated primarily by the need for resources such as timber and various other minerals. The Athens assembly further aggravated the situation by placing an economic embargo on the city of Megara, which was a former ally of Athens that turned on Sparta. Sparta held a meeting with both Athens and Megara to determine what to do about the situation. The citizens of Sparta wanted war with Athens, but King Archidamus did not want to recklessly rush into a war with another empire. However, war was the vote according to the Spartan assembly. Sparta then addressed the issue with Pel... middle of paper... opening a new chapter for the Greek people. As it allowed Philip II from Macedonia to invade and unite Greece with ease. The Peloponnesian War could easily be considered one of the most significant and life-changing wars to occur in classical Greece. It was fought between two empires that originally opposed a common enemy, the Persians. However, once this common enemy was defeated, Sparta and Athens began to become major rivals vying for control of Greece. This resulted in the First and Second Peloponnesian Wars, which saw the rise and fall of the Athenian empire. Sparta eventually became the victor with the help of their former enemy, Persia, but the age of city-states would not survive long. The Peloponnesian Wars should be studied, because they detail the rise and fall of one of the greatest city-states in Greek history.
