Ancient Greek warfare shaped the classical world, from the rise of city-states to the conquests of Alexander the Great. Hoplites, phalanxes, and triremes defined Greek military might, while battles like Marathon and Thermopylae became legendary. Greek military innovations influenced art, literature, and philosophy. The Spartan ethos of discipline and the Athenian naval empire left lasting legacies. Roman tactics and modern strategy still draw inspiration from Ancient Greek warfare.
