Ancient warfare is war that was conducted from the beginning of recorded history to the end of the ancient period. The difference between prehistoric and ancient warfare is more organization oriented than technology oriented. The development of first city-states, and then empires, allowed warfare to change dramatically. Beginning in Mesopotamia, states produced sufficient agricultural surplus. This allowed full-time ruling elites and military commanders to emerge. While the bulk of military forces were still farmers, the society could portion off each year. Thus, organized armies developed for the first time. These new armies were able to help states grow in size and become increasingly centralized.

In Europe and the Near East, the end of antiquity is often equated with the Fall of Rome in 476 AD, the wars of the Eastern Roman Empire on its Southwestern Asian and North African borders, and the beginnings of the Muslim conquests in the 7th century. In China, it can also be seen as ending of the growing role of mounted warriors needed to counter the ever-growing threat from the north in the 5th century and the beginning of the Tang dynasty in 618 AD. In India, the ancient period ends with the decline of the Gupta Empire (6th century) and the beginning of the Muslim conquests there from the 8th century. In Japan, the ancient period is considered to end with the rise of feudalism in the Kamakura period in the 12–13th century.

Early ancient armies continued to primarily use bows and spears, the same weapons that had been developed in prehistoric times for hunting. The findings at the site of Nataruk in Turkana, Kenya, have been interpreted as evidence of inter-group conflict and warfare in antiquity,^[1] but this interpretation has been challenged.^[2] Early armies in Egypt and China followed a similar pattern of using massed infantry armed with bows and spears. Infantry at this time was the dominant form of war, partially due to the camel saddle and the stirrup not being invented yet. The infantries at this time would be divided into ranged and shock, with shock infantry either charging to cause penetration of the enemy line or hold their own. These forces would ideally be combined, thus presenting the opponent with a dilemma: group the forces and leave them vulnerable to ranged, or spread them out and make them vulnerable to shock. This balance would eventually change as technology allowed for chariots, cavalry, and artillery to play an active role on the field.

No clear line can be drawn between ancient and medieval warfare. The characteristic properties of medieval warfare, notably heavy cavalry and siege engines such as the trebuchet were first introduced in Late Antiquity. The main division within the ancient period is at the beginning Iron Age with the introduction of cavalry (resulting in the decline of chariot warfare), of naval warfare (Sea Peoples), and the development of an industry based on ferrous metallurgy which allowed for the mass production of metal weapons and thus the equipment of large standing armies. The first military power to profit from these innovations was the Neo-Assyrian Empire, which achieved a hitherto unseen extent of centralized control, the first "world power" to extend over the entire Fertile Crescent (Mesopotamia, the Levant and Egypt).
