'''War''' is a prolonged state of violent conflict between two states.  Even though war is a violation of the Bible's sixth commandment, it has been conducted for many purposes, such as the acquisition of goods, seizing enemy territory, to satisfy the honor of the [[sovereign]], eliminating a threat to the homeland, stamping out rival religious sects (see [[Religious_war]]), or exporting political ideologies.  Warfare between factions within a single [[state]] is called [[civil war]].

Wars have often been periods of great technological innovation as each side finds itself faced with the necessity of creating new methods of offense and defense to ensure national survival.  The [[American Civil War]], coming only a decade after the [[Industrial revolution]] took root in the United States, introduced mechanized warfare to the world with metal [[warship]]s, [[railway|railroad]] transportation of forces and material, and instant communication via the [[telegraph]].  The conflict known as the Great War (later called [[World War I]]) introduced air combat, [[chemical warfare]], [[submarine]] and [[tank (military)|tank]] warfare, and the large scale deployment of the [[machine gun]].  [[World War II]] refined tank tactics in the form of the [[Blitzkrieg]] as the [[aircraft carrier]] took mastery of the seas.  It ended with the first use of [[nuclear weapon]]s in wartime.
