List of wars and anthropogenic disasters by death toll
This is a list of wars and anthropogenic disasters by death toll. The list covers the name of the event, location and the start and end of each event. Some events may belong in more than one category. In addition, some of the listed events overlap each other, and in some cases the death toll from a smaller event is included in the one for the larger event or time period of which it was part. There is often large uncertainty about the death tolls. The tables are initially sorted by  the geometric mean, meaning the square root of the product of the lowest and highest estimate, of the cumulative number of deaths. For example, formula_1 for a lowest estimate of 500 and highest 2000 dead since start of the war or disaster. War. Wars and armed conflicts. This section lists all wars and major conflicts in which the highest estimated casualties exceeds 100,000. This includes deaths of both soldiers, civilians, etc. from causes both directly and indirectly caused by the war, which includes combat, disease, famine, massacres, suicide, and genocide. Mistreatment of civilians during war. "This section lists non-combatant  deaths during wars that were purposefully committed or caused by military or quasi-military forces with the intent of harm (deaths due to wartime shortages, for example, are not included as they are a side effect of war). They may not particularly target ethnic, religious, or political groups but are usually part of a military strategy that disregards civilian lives, or they may be arbitrary acts of cruelty."
