The second Peloponnesian war (oct 27, 431 BC – mar 27, 413 BC)

Description:

This was the war between Athens and Sparta. There were 3 phases to this war. 'The first phase was of the Archidamian War in which where Sparta repeatedly invaded Attica, Athens took advantage of its supremacy over the seas and raided the Peloponnese’s coast. They attempted to deploy the signs of disruption in their areas. This phase of the war ended with the signing of a treaty between the two leagues i.e. Peace of Nicias in 421 BC. The treaty was undermined with the renewed fights between the Athens and Sparta. In 415 BC, Athens executed a huge expeditionary force to attack the city of Syracuse. This attack failed ridiculously posing the destruction of the entire enormous army, in 413 BC." (https://www.ancienthistorylists.com/greek-history/top-10-important-events-of-ancient-greece/)
