formallegalmilitary

In international humanitarian law, the principle that the military advantage anticipated from an attack must not be excessive in relation to the civilian casualties or damage to civilian objects expected to result.

This principle requires a careful balancing act, weighing the military necessity against potential harm to non-combatants and civilian infrastructure. It does not prohibit all civilian harm, but rather excessive harm.

The story behind the word. The word 'proportionality' comes from the Latin proportio, meaning 'for a part' or 'in relation to a part'. It entered English in the 15th century, initially in a mathematical sense. Its specific application to international law and the conduct of warfare, particularly regarding the balance between military advantage and civilian harm, became formalized in the 20th century with the development of international humanitarian law.
