While the war may have been over, relations between Athens and Sparta continued to deteriorate. Athens continued to grow in power and began to pose a threat to Sparta and the Peloponnesian League. A series of conflicts broke out during the "Thirty Years' Peace" which once again pushed Sparta and Athens to war. For example, Athens intervened in a conflict between a colony and a city-state during the Corinthian-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 it would not be the last time Athens clashed with Corinth. Soon after, a Corinthian colony called Potidaea revolted against its rulers. Athens wished to intervene, but the Spartans quickly sided with Potidaea. Sparta threatened to invade Attica (the area Athens is located in) if Athens decided to attack Potidaea. Athens would not be threatened by this and war would begin to become inevitable. Ignoring the fact that Potidaea was officially protected by Sparta, Athens set about besieging Potidaea. This decision was primarily driven by the need for resources such as wood and various other minerals. The Athens assembly further aggravated the situation by imposing an economic embargo on the city of Megara, a former ally of Athens turned towards Sparta. Sparta held an assembly with Athens and Megara to determine what to do about the situation. The citizens of Sparta wanted war with Athens, but King Archidamos did not want to recklessly embark on a war with another empire. However, the war was the vote according to the Spartan assembly. Sparta then took up the matter with the Pel...... middle of paper ...... opening a new chapter for the Greek people. As it allowed Philip II of Macedon to easily invade and unite Greece, the Peloponnesian War could easily be considered one of the most notable and defining wars of classical Greece. It opposed two empires which, originally, united against a common enemy, the Persians. However, once this common enemy was defeated, Sparta and Athens began to become arch 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 victorious with the help of its ancient enemy Persia, but the era of city-states would not survive for very long. The Peloponnesian Wars should be studied, as they detail the rise and fall of one of the greatest city-states in Greek history..
