Panthay Rebellion
ND – MPE: 0.6
White cites three sources, which claim than 1 million people died during the Panthay Rebellion in China from 1855 to 1873. It remains unclear how many of these war deaths were civilians and how many of them died from war-related diseases. Plausible estimates for the number of innocent people killed during the Panthay Rebellion range from 0.3 to 0.9 million. I choose 0.6 million as the most plausible estimate.
The imperial government was helped by French military experts.
