The Unparalleled Invasion is a rare political anticipation short story written by Jack London and first published in McClure's in July 1910 and later in the book The Strength of the Strong (New York, Macmillan, 1914). The story begins in 1910s China. Under the influence of Japan, China modernizes and has its own Meiji Reforms. In 1922, China breaks away from Japan and fights a brief war that culminates in the Chinese annexation of the Japanese possessions of Korea, Formosa, and Manchuria. Over the next half century, China's population steadily grows, and eventually migration overwhelms European colonies in Asia. The United States of America and the other Western powers launch a biological warfare campaign against China, resulting in the decimation of China's population. China is then colonized by the Western powers.
