Outline of war

The following outline is provided as an overview of and topical guide to war:

War – organised and often prolonged armed conflict that is carried out by states or non-state actors – is characterised by extreme violence, social disruption, and economic destruction. War should be understood as an actual, intentional and widespread armed conflict between political communities, and therefore is defined as a form of political violence or intervention.

Warfare refers to the common activities and characteristics of types of war, or of wars in general.
