Introduction

Austerlitz-baron-Pascal.jpg
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.

Conrad III of Germany personally led the crusade

The Second Crusade was the second major crusade launched from Europe, called in 1145 in response to the fall of the County of Edessa the previous year. Edessa was the first of the Crusader states to have been founded during the First Crusade, and was the first to fall. The Second Crusade was announced by Pope Eugenius III, and was the first of the crusades to be led by European kings, namely Louis VII of France and Conrad III of Germany. The armies of the two kings marched separately across Europe and were separately defeated by the Seljuk Turks. Louis and Conrad and the remnants of their armies reached Jerusalem and in 1148 participated in an ill-advised attack on Damascus. The crusade in the east was a failure for the crusaders and a great victory for the Muslims. It would ultimately lead to the fall of Jerusalem and the Third Crusade at the end of the 12th century. The only success came on the opposite end of the Mediterranean, where English crusaders, on the way by ship to the Holy Land, fortuitously stopped and helped capture Lisbon in 1147.
