Asia
- Japanese soldiers during the final assault on Nanjing’s gates in the Battle of Nanjing
The most significant event in Asian history on December 13 is the beginning of the Nanjing Massacre in 1937. On this day, during the Second Sino-Japanese War, Japanese forces captured Nanjing (then the capital of the Republic of China) and began a period of mass killings and atrocities against Chinese civilians and disarmed soldiers. The violence, which continued for several weeks, resulted in the deaths of an estimated 100,000 to over 300,000 people, with widespread reports of mass executions, rape, and destruction. In recognition of this tragedy, China observes December 13 as the National Memorial Day for the Victims of the Nanjing Massacre. Established in 2014, this annual memorial day honors not only the victims of the massacre but also all Chinese who suffered during the Second Sino-Japanese War, including those affected by chemical and biological warfare, forced labor, and other war crimes. The day is marked by ceremonies at the Memorial Hall in Nanjing, moments of silence, air raid sirens, and public remembrance activities to ensure the events are not forgotten and to promote peace. - International Impact and Remembrance
The Nanjing Massacre is globally recognized as one of the most horrific episodes of World War II in Asia. The events have been commemorated by UNESCO, and new evidence and survivor testimonies continue to emerge, reinforcing the importance of historical memory.
