Taiping Rebellion

The Taiping Rebellion (1850–1864) was a civil war in late imperial China fought between the ruling Qing dynasty and the rebelling Taiping Heavenly Kingdom. It was the deadliest civil war in history and the second-deadliest conflict in history overall. Estimates of the war's death toll range from 20–30 million, around 5–10% of the total Chinese population at the time, to 73–100 million, around 25% of the population.
