Peloponnesian War (431–404 BC) between the Peloponnesian League (headed by Sparta) and the Delian League (led by Athens). Thucydides, an Athenian historian who served as an Athenian general during the war, wrote it. His description of the fight is widely regarded as a classic and one of the first scholarly publications on the subject. There are eight books in the History.
Thucydides' technique has been the subject of extensive examination in the field of historiography because he is considered one of the main characters in the creation of Western history.
The majority of historical analyses fall into one of two categories. [1] On the one hand, some historians, such as J. B. Bury, regard the work as objective and scientific. J. B. Bury describes the History as "strict in its detachment, written from a purely intellectual point of view, free of clichés and moral judgments, frigid and analytical."
