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

A common look on 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 characterized as a "war of liberation", while a war between internal elements of the same state is called a civil war.

Aside from humans and other primates, ants are the only other animals 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 and analysis of those events in the history of humanity that fall within the category of organized armed conflict and that relates to the institutions and organizations that prosecute such conflict.

JMW Turner's 'Battle of Trafalgar' shows the last three letters of this famous signal

"England expects that every man will do his duty" was a signal sent by Admiral Horatio Nelson, 1st Viscount Nelson from his ship HMS Victory as the Battle of Trafalgar (1805) was about to commence. Trafalgar was the decisive naval engagement of the Napoleonic Wars. It gave the United Kingdom control of the seas, removing all possibility of a French invasion and conquest of Britain. The phrase has become extremely well-known in Britain as a result of Lord Nelson's fame and the importance of the Battle of Trafalgar in British history. The phrase is known so widely in Britain that it has entered the British popular consciousness. Today "England expects…", as an abbreviated version of the phrase, is often adapted for use in the media, especially in relation to the expectations for the victory of English sporting teams.

The Polish–Soviet War (14 February 1919 – 18 March 1921) was fought primarily between the Second Polish Republic and the Russian Soviet Federative Socialist Republic in the aftermath of World War I, on territories formerly held by the Russian Empire and the Austro-Hungarian Empire.

In newly independent (from November 1918) Poland, leading politicians of different orientations pursued the general expectation of restoring the pre-1772 (First Partition of Poland) borders. Motivated by that idea, Polish Chief of State Józef Piłsudski aimed to expand Poland's eastern frontiers (actual borders had yet to be determined) to the east and began moving troops in that direction.
