War

is a state of armed conflict between different nations or states, or different groups within a nation or state. It is a part of almost every game on this wiki.
In Civilization IV and beyond, players can declare war on each other through the diplomacy screen. AI leaders are more likely to declare war on a human player who has a weak military and/or is close to achieving victory.
Being at war provides opportunities to capture cities, pillage tile improvements for gold and other spoils, progress toward a Conquest or Domination Victory, and impede opponents' victory progress. However, it also cancels any trade deals, worsens relationships with other civilizations, and causes the aggressor to suffer warmonger penalties and both parties to suffer war weariness.
