Middle Kingdom Lost: From the Invention of Gunpowder to the Nanjing Massacre explores one of history's great paradoxes: if China invented gunpowder, firearms, the compass, and many other technologies centuries before the West, how did foreign powers later defeat China using those same innovations? Tracing the development of gunpowder weapons from Tang China to World War II, Nan-Yao Su examines the institutional divergence that separated China, Europe, and Japan. Gunpowder originated in China and spread across Eurasia through the Mongol Empire. In Europe, the Black Death, Renaissance, Scientific Revolution, and intense interstate warfare fostered continuous military and technological innovation. In China, a centralized imperial system increasingly prioritized stability over military competition. Japan, after centuries of warfare, rapidly modernized during the Meiji era and successfully adopted Western institutions and technology. The result was a widening military gap that culminated in China's defeats during the Opium Wars, the First Sino-Japanese War, and ultimately the Nanjing Massacre. This book argues that China's decline was not caused by cultural inferiority, but by centuries of institutional divergence.
