The enduring importance of The History of the Peloponnesian War resides in its ability to prepare the reader to recognise historical patterns hidden in chaos regarding the human element in war. Using the model of historical study proposed by Sir Michael Howard, the span of Thucydides’ account allows the reader to study war in width and examine continuities, trends, and patterns in human behaviour in war. By incorporating both chronological events and the speeches of key decision makers into his argument, Thucydides provides an opportunity to study in depth the chaos and uncertainty inherent in war. Finally, by expanding his analysis to include the cultures of the societies participating in the conflict, Thucydides enables the reader to study the context within which the war was fought.
