War is the business of barbarians.

Attributed to Napoleon, the line frames war not as a noble calling but as a mark of “barbarism,” implying that organized violence belongs to societies (or leaders) lacking refinement, restraint, or true civilization. Read this way, the aphorism functions as a moral inversion of the traditional heroic rhetoric of battle: it suggests that the more “civilized” a polity becomes, the less it should rely on war as an instrument of policy. The attribution is often used polemically—especially given Napoleon’s own career—to highlight the tension between pragmatic statecraft and ethical judgment, or to underscore the hypocrisy that can accompany militaristic ambition.
