List of wars by death toll


 * This list is incomplete; you can help by [ expanding it.]

This list of wars by death toll includes all deaths that are either directly or indirectly caused by the war. These numbers usually include the deaths of military personnel which are the direct results of a battle or other military wartime actions, as well as the wartime/war-related deaths of civilians which are the results of war-induced epidemics, famines, atrocities, genocide, etc.

Ancient wars (before 500 AD)
Note 1: The geometric mean is the middle of the quoted range, taken by multiplying together the endpoints and then taking the square root.

Medieval wars (500–1500 AD)
Note: the identity of a single "war" cannot be reliably given in some cases, and some "wars" can be taken to last over more than a human lifetime, e.g. "Reconquista" (711–1492, 781 years) "Muslim conquests in the Indian subcontinent" (12th to 16th c., 500 years) "Crusades" (ten or more campaigns during the period 1095–1291, 196 years), "Mongol invasions and conquests" (1206–1368, 162 years), "early Muslim conquests" (622–750, 128 years), "Hundred Years' War" (1337–1453, 116 years).
