“Thucydides was one of the greatest Greek historians who is known for his Magnus opus, “History of Peloponnesian War”. This account of the great Peloponnesian War is not exactly complete as it only presents the events that took place during 431 to 411 B.C. But the reason why it is remembered and read as one of the most perfect Greek literatures is because it reflects Thucydides? genuinely original style interspersed with wisdom and objectivity which most other historians of that period lacked. There is still some confusion about the exact year of his birth as some ancient historians have given dates, which clash with dates provided by modern researchers. But for the sake of convenience, it is believed that he was born somewhere around 460 B.C. and died in 400 B.C. The year of his birth may cause confusion but one thing is clear; the man was certainly present during the Peloponnesian war in which he actively participated only to be exiled to Sparta. He was a military general and thus possessed in-depth knowledge of military skills and techniques. He has thus provided his readers with accurate account of he military tactics used by both Spartans and Athenians during the Peloponnesian war. ”
