It’s one of the bloodiest conflicts in human history. In 1851, the Taiping Rebellion exploded in Qing dynasty China, causing death on an unprecedented scale. Over 14 years of civil war, an estimated 20 million people died, more than were killed in the whole of WWI. It was, simply, the deadliest war of the nineteenth century, and it was all thanks to one man: Hong Xiuquan.
