History of the Peloponnesian War

History of the Peloponnesian War is an account of the battles and conflicts of the Peloponnesian War between the Peloponnesian League (Sparta) and the Delian League (Athens), written by an Athenian general who served in the war, Thucydides.

Thucydides' History begins almost exactly where Herodotus' Histories leaves off. Unlike Herodotus, who openly admitted to recounting popular beliefs in cases when evidence was lacking or insufficient, Thucydides aimed to provide an acurate and detailed account, thoroughly citing his sources whenever he could not provide a first-hand account.
