In the years leading up to and including World War II, the Japanese invaded China, committing war crimes and atrocities that some say rivaled those committed by the German National Socialist (Nazi) Party in Europe. However, due to a number of factors following the
end of World War II, many conflicting points of view about Nanjing have arisen, including views from Japanese ultranationalists, Chinese victims and their descendants, and from other outside parties, including Americans and Europeans.
In the present day, the evidence and the different testimonies of what may have happened in Nanjing have become so convoluted that it would be impossible to come up with a purely factual, unbiased historical account of the events in Nanjing during the Japanese invasion on
December 13, 1937 and the weeks leading up to and following that invasion. By looking at some of the most popular sources and references pertaining to the Nanjing Massacre, one can assess just how disputed the topic has become and how truly impossible it is for historians to
arrive at a single, agreed upon history of the event.
