Was the twentieth century the most violent in history? Are religions or tyrants, capitalism or communism the cause of most human suffering? Has violence increased or decreased over the course of history?In this wholly original and remarkably ambitious work, 'Atrocitologist' Matthew White considers man's inhumanity to man across several thousand years of history. From the First Punic War and the collapse of Mayan rule, to the reign of Peter the Great and the cataclysmic events of the Second World War, White's epic book spans centuries and civilisations as it measures the hundred most violent events in human history. While sceptical of any grand theory for the causes of human violence, White does share three big lessons gleaned from his careful statistical analysis: one, chaos is more deadly than tyranny; two, the world is even more disorganised than we realise; and three, wars kill more civilians than soldiers (in fact, the army is usually the safest place to be).If we study history to avoid the mistakes of the past, then there can be no more important place to start than this eye-opening and entertaining book.
