Ancient Greek warfare

Warfare occurred throughout the history of Ancient Greece, from the Greek DarkAges onward. The Greek DarkAges 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 (800–480BC). 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 AncientGreek 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 hoplitephalanx. 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 650BC, 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.
The scope and scale of warfare in Ancient Greece changed as a result of the Greco-PersianWars, which marked the beginning of Classical Greece (480–323BC). To battle the enormous armies of the Achaemenid Empire was effectively beyond the capabilities of a single city-state. The eventual triumph of the Greeks was achieved by alliances of many city-states, on a scale and scope never seen before.
The rise of the naval power of Athens in competition with the dominant land power of Sparta after this conflict led directly to the Peloponnesian War, which saw diversification of warfare. Emphasis shifted to naval battles and strategies of attrition such as blockades and sieges. Following the defeat of the Athenians in 404BC, and the disbandment of the Athenian-dominated Delian League, AncientGreece fell under the Spartan hegemony. But this was unstable, and the PersianEmpire sponsored a rebellion by the combined powers of Athens, Thebes, Corinth and Argos, resulting in the Corinthian War (395–387BC). Persia switched sides, which ended the war, in return for the cities of Ionia and Spartan non-interference in Asia Minor.
The Spartan hegemony would last another 16years, until, at the Battleof Leuctra (371BC) the Spartans were decisively defeated by the Theban general Epaminondas. The Thebans acted with alacrity to establish a hegemony of their own over Greece. However, Thebes lacked sufficient manpower and resources, and became overstretched. Following the death of Epaminondas and loss of manpower at the Battleof Mantinea, the Theban hegemony ceased. The losses in the tenyears of the Theban hegemony left all the Greek city-states weakened and divided. The city-states of southern Greece were now too weak to resist the rise of the Macedonian kingdom under Philip II. With revolutionary tactics and a reformed Macedonian army, Philip II of Macedon brought most of Greece under his sway, paving the way for the conquest of "the known world" by his son Alexander theGreat. The rise of the Macedon marked the end of the distinctive hoplite battle.
