War is a terrible phenomenon and one can uncover multiple layers of evil when evaluating just how bad a war is. One way to compare wars in history is to look at the loss of life during each war. Using that calculation, the worst wars in history become horrifically obvious.
Seven of the Worst Wars in History:
1. The Napoleonic Wars (1803-1815) – Between 3.5 and 6 million people were killed in the wars Napoleon Bonaparte waged in the early 19th century. The Napoleonic Wars were some of the worst wars in history partly because of the widespread use of mass conscription, which was applied at an unprecedented scale during this war.
2. The Russian Civil War (1917-1922) – Some five to nine million people died in the Russian Civil War, which took place in the years that followed the collapse of the Russian Empire and the death of the last Russian Czar.
3. World War I (1914-1918) – An estimated 20 million people were killed in the first World War, then also known as the Great War. Erupting in Europe after the death of Archduke Franz Ferdinand, World War I is one of the worst wars in history partially because it was among the first wars to have been fought using modern warfare tactics. Up until then, no one had ever seen a war of such scale, and the resulting trauma rippled through several generations.
4. An Lushan Rebellion (755-763 AD) – The An Lushan Rebellion happened in the Chinese Tang Dynasty when a Tang general established a rival dynasty in the North. Despite some disagreements about the reliability of the census system during the time, experts estimate between 13 and 36 million casualties.
5. Qing Dynasty Conquest of the Ming (1618-1683) – The Qing Dynasty is known for being the last of the old Chinese dynasties before the beginning of the Republic, but an estimated 25 million people died in the Conquest of the Ming before the Qing Dynasty began.
6. Taiping Rebellion (1850) – During the Taiping Rebellion, a convert to Christianity named Hong Xiquan led a rebellion against the Manchu Qing Dynasty, during which anywhere between 20 to 100 million people (mostly civilians) were killed.
7. World War II (1938-1945) – With a death toll between 40 and 85 million, the Second World War was the deadliest and worst war in history. Experts estimate with such a high death toll, about three percent of the world’s population in 1940 died.
While the wars listed above are some of the worst wars in history, one must be careful not to forget that deadly wars are being fought today all around the globe as well. These may be the worst wars in history, but who’s to say that the worst war of all isn’t one being fought right now?
