A failed scholar falls into a fever dream and wakes convinced he is the younger brother of Jesus Christ. Within a decade, that conviction has become an army of a million believers, a captured capital, and a kingdom that rules over more people than most nations on earth. This book traces the full, staggering arc of the Taiping Rebellion, the deadliest civil war in human history, from the eroding soil and simmering ethnic tensions of a collapsing Qing empire to the palace intrigues, purges, and battlefield triumphs of a movement that nearly remade China entirely. Hong Xiuquan's visions carry the Heavenly Kingdom from a Guangxi hillside to the walls of Nanjing, while generals like Li Xiucheng and Chen Yucheng fight to hold together a cause fracturing from within even as foreign powers, missionaries, and mercenaries circle a war too vast to ignore. It ends in famine, fire, and a starving capital's final collapse, but not before raising questions about faith, justice, and revolution that would outlive the kingdom itself by a century. Drawing on firsthand testimony, missionary letters, and the rediscovered confession of a condemned general, this is narrative history at its most immersive: intimate, brutal, and impossible to put down.
