Margaret mead's theory of war in her 1940 article titled "Warfare is only an invention not a biological necessity," proposed that war is merely human invention and dismissed the notion that war is the inevitable consequence of human competitiveness because not all societies wage war against themselves.
Mead believe's that warfare is human invention because it does not happen in all the societies around the world, She describes war as conflict between two groups of individuals or society.
