Chigi vase in the context of "Name vase"

Warfare occurred throughout the history of Ancient Greece, from the Greek Dark Ages onward. The Greek Dark Ages drew to an end as a significant increase in population allowed urbanized culture to be restored, which led to the rise of the city-states (poleis). These developments ushered in the period of Archaic Greece (800–480 BC). They also restored the capability of organized warfare between these poleis (as opposed to small-scale raids to acquire livestock and grain, for example). The fractious nature of Ancient Greek society seems to have made continuous conflict on this larger scale inevitable.

Along with the rise of the city-state evolved a new style of warfare: the hoplite phalanx. Hoplites were armored infantrymen, armed with spears and shields. Seen in media, the phalanx was a formation of these soldiers with their shields locked together and spears pointed forward. The Chigi vase, dated to around 650 BC, is the earliest depiction of a hoplite in full battle array. With this evolution in warfare, battles seem to have consisted mostly of the clash of hoplite phalanxes from the city-states in conflict. Since the soldiers were citizens with other occupations, warfare was limited in distance, season and scale. Neither side could afford heavy casualties or sustained campaigns, so conflicts seem to have been resolved by a single set-piece battle.
