Thucydides explains the next contributing factors for the cause of the Peloponnesian War was the dispute over the Corcyraeans. The dispute over Corcyra was a result from the dispute of the Epidamnus, and leads to the dispute of the Potidaea. The Corinthians were not backing down, following the war against the Corcyraeans, Corinthians spent time and money building new ships and trained rowers from the Peloponnese to fight against Corcyra. The Corcyra never joined the Athenian League or the Spartans, which made them nervous to fight the Corinthians because they did not have enough man power or allies. Knowing the Corinthians might have a chance to win in a second battle, Corcyra sought the help of Athens. Ironically, Athens was already a party to the Peace Treaty of the Peloponnesian, and had ties to the Corintheans because they too were involved in the treaty. Regardless of the treaty, Athens decided to hear both sides of the argument before deciding which city to side with. The hearing in Athens between the Corinthians and the Corcyraeans was a major factor of the Peloponnesian War because Athens took the Corcyraeans side and put their own city at risk and in an unsettling position.
What were the causes of the Peloponnesian War? - Answers
The causes of the main Peloponnesian War need to be traced at least to the early 430s, although if Thucydides was right in his general explanation for the war, namely Spartan fear of Athenian expansion, the development of the entire 5th century and indeed part of the 6th were relevant. In the early 430s Pericles led an expedition to the Black Sea, and about the same time Athens made an alliance with a place close to areas of traditional Corinthian influence, Acarnania. (On another view this belongs in the 450s.) In 437 Athens fulfilled an old ambition by founding a colony at Amphipolis, no doubt on a large scale, though figures for settlers do not exist. This was disconcertingly close to another outpost of Corinthian influence at Potidaea in the Chalcidice, and there is a possibility that Athens subjected Potidaea itself to financial pressure by the mid-430s. That city was an anomaly in being both tributary to Athens and simultaneously subject to direct rule by magistrates sent out annually by Corinth; it clearly was a sensitive spot in international relations. Thus to the west (Acarnania and other places) and northeast (Amphipolis, Potidaea) Corinth was being indirectly pressured by Athens, and this pressure was also felt in Corinth's own backyard, at Megara. Athens passed a series of measures (the "Megarian decrees") imposing an economic embargo on Megara for violations of sacred land. The religious aspect of the offense was reflected in the exclusions imposed: like murderers, the Megarians were banned from the Athenian marketplace and the harbours in the Athenian empire. But one should not doubt that Athens caused and intended to cause economic hardship as well or that the decrees were the first move in securing Megara as a military asset, a line of policy further pursued in the years 431 to 424.
The Causes of the Peloponnesian War
According to mythology. Corfu has been identified with the island of Faeakes mentioned by Homer. The archaeological researches, though have not proved it. In 734 B.C., Corfu was colonised by the Corinthians and became independent. It was the second naval power after Athens. Its democratic regime as well as its refusal to subordinate to Corinth was the cause of the Peloponnesian War. Its power kept being significant during the 4th cent B.C., when it fought on Athens side (battle of Heronia, 338 B.C. ).
