The complex role warfare played in ancient Greek and Roman civilizations is examined through coverage of key wars and battles; important leaders, armies, organizations, and weapons; and other noteworthy aspects of conflict.

Conflict in Ancient Greece and Rome: The Definitive Political, Social, and Military Encyclopedia is an outstandingly comprehensive reference work on its subject. Covering wars, battles, places, individuals, and themes, this thoroughly cross-referenced three-volume set provides essential support to any student or general reader investigating ancient Greek history and conflicts as well as the social and political institutions of the Roman Republic and Empire.

The set covers ancient Greek history from archaic times to the Roman conquest and ancient Roman history from early Rome to the fall of the Western Roman Empire in 476 CE. It features a general foreword, prefaces to both sections on Greek history and Roman history, and maps and chronologies of events that precede each entry section. Each section contains alphabetically ordered articles—including ones addressing topics not traditionally considered part of military history, such as "noncombatants" and "war and gender"—followed by cross-references to related articles and suggested further reading. Also included are glossaries of Greek and Latin terms, topically organized bibliographies, and selected primary documents in translation.
