For three decades in the fifth century b.c. the ancient world was torn apart bya conflict that was as dramatic, divisive, and destructive as the world wars of the twentieth century: the Peloponnesian War. Donald Kagan, one of the world’s most respected classical, political, and military historians, here presents a new account of this vicious war of Greek against Greek, Athenian against Spartan. The Peloponnesian War is a magisterial work of history written for general readers, offering a fresh examination of a pivotal moment in Western civilization. With a lively, readable narrative that conveys a richly detailed portrait of a vanished world while honoring its timeless relevance, The Peloponnesian War is a chronicle of the rise and fall of a great empire and of a dark time whose lessons still resonate today.
