Deadliest Civil War Was the Taiping Rebellion

Superfact 93 : Around 20 to 30 million people died in the Taiping Rebellion, 1850 to 1864. It is the deadliest civil war in known history, the deadliest war in the 19th century, and the second deadliest war in all of known history. World War II was the deadliest.

The graphics show differently colored circles corresponding to selected large wars. World War II – 80 million, Mongol conquests – 45 million, Taiping Rebellion – 25 million, World War I – 18 million, Russian Civil War – 10 million, Chinese Civil War 7 million, 30 years’ war 6 million, Napoleonic Wars – 5 million, Second Congo Civil War 4 million, Vietnam War 2.45 million, American Civil War 0.7 million.
The number of deaths cited in the graphics above are rough midpoint values of the estimates. The area of the circles corresponds to these midpoint estimates. Note Mongol conquests correspond to multiple wars during a time period of 162 years. The ‘M” corresponds to millions.

The Taiping rebellion is estimated to have caused the deaths of 20-30 million people. However, some estimates estimate that as many as 70 million people might have died in the Taiping rebellion. The Mongol invasions and conquests cost 30-60 million lives, but they comprised many wars and took place during a time period of 162 years (1206 – 1368). Therefore, you typically don’t count that as one war. Also note that the estimate for deaths caused by World War I does not include the Spanish flu.

I consider this a super fact because it is true, an important history fact and despite the enormous losses in the Taiping rebellion, a lot of people have never heard of it.

The Taiping Rebellion

The Taiping Rebellion was a civil war in China between the Qing dynasty and the Taiping Heavenly Kingdom. The Taiping Heavenly Kingdom was a theocratic monarchy that tried to overthrow the Qing dynasty. It was led by Hong Xiuquan, a religious leader who believed he was Jesus younger brother. In the end the Qing dynasty prevailed but at a great cost.

My name is Thomas Wikman. I am a software/robotics engineer with a background in physics. I am currently retired. I took early retirement. I am a dog lover, and especially a Leonberger lover, a home brewer, craft beer enthusiast, I’m learning French, and I am an avid reader. I live in Dallas, Texas, but I am originally from Sweden. I am married to Claudia, and we have three children. I have two blogs. The first feature the crazy adventures of our Leonberger Le Bronco von der Löwenhöhle as well as information on Leonbergers. The second blog, superfactful, feature information and facts I think are very interesting. With this blog I would like to create a list of facts that are accepted as true among the experts of the field and yet disputed amongst the public or highly surprising. These facts are special and in lieu of a better word I call them super-facts.

    1. Still, that is just a short list of the worst. Well the top half of the list is the worst. The second half is the worst of the more recent wars. There’s been thousands of wars claiming several hundreds of millions of lives throughout history. The worst war in this century was the Congo Civil War.
