Introduction

The Battle of Austerlitz by François Gerard.
War is a state of conflict between relatively large groups of people (such as nations, states, organizations, social groups), which is characterized by the use of armed lethal violence between combatants or upon civilians. Other terms for war, which often serve as euphemisms, include armed conflict, hostilities, and police action.

A common perception of war is a series of military campaigns between at least two or more opposing sides involving a dispute over sovereignty, territory, resources, ideology or a host of other issues. A war to liberate an occupied country is sometimes characterised as a "war of liberation", while a war between internal elements of the same state may constitute a civil war.

Aside from humans and their primate brethren, ants are the only other species known to exhibit such behavior on a large scale.

A battle is a single engagement fought between two or more parties, wherein each party or aligned group will seek to defeat their opponent. Battles are most often fought during military campaigns and can usually be well defined in time, space and action. Wars are generally the continuum of a related series of battles and are guided by strategy, whereas individual battles are the stage on which tactics are employed.

Military history is the recording of those events in the history of humanity that fall within the category of organised armed conflict.

Capture of Jerusalem in 1099

The First Crusade was a crusade launched in 1095 by Pope Urban II to regain control of the sacred city of Jerusalem and the Christian Holy Land from Muslims. What started as a minor call for aid quickly turned into a wholesale migration and conquest of territory outside of Europe. Both knights and peasants from many different nations of western Europe, with little central leadership, travelled overland and by sea towards Jerusalem and captured the city in July 1099, establishing the Kingdom of Jerusalem and the other Crusader states. Although these gains lasted for fewer than 200 years, the Crusade was a major turning point in the expansion of Western power, and was the only crusade out of the many that followed to achieve its stated goal.
