How and why did the Nanking Massacre begin?
The Nanking Massacre, commonly known as the Rape of Nanking, was an infamous genocidal war crime committed by the Japanese military in Nanjing, then capital of the Republic of China, after it fell to the Imperial Japanese Army on December 13, 1937. The duration of the massacre is not clearly defined, although the violence lasted well into the next six weeks, until early February 1938.
