Nanking

Nanking (Nanjing) was the Chinese capital city where, in 1937-1938 during the Second Sino-Japanese War, the Imperial Japanese Army massacred and brutalized hundreds of thousands of Chinese civilians, making it a major example of mass atrocities after 1900 in AP World Topic 7.8.

What is Nanking?

Nanking (today spelled Nanjing) was the capital of Nationalist China when Japanese forces captured it in December 1937 during the Second Sino-Japanese War. What followed over roughly six weeks is known as the Nanjing Massacre or the Rape of Nanking. Japanese soldiers killed, tortured, and sexually assaulted civilians and surrendered soldiers on a massive scale, with death toll estimates reaching as high as 300,000.

For AP World, Nanking is more than a single horrific event. It sits inside Topic 7.8, Mass Atrocities After 1900, which asks you to explain the causes and consequences of genocide, ethnic violence, and attempted destruction of populations in the 20th century. Nanking shows how extreme nationalism, imperial expansion, and total war created the conditions for state militaries to target civilians. It also connects directly to other Japanese wartime policies, like the systematic sexual enslavement of "comfort women" and forced labor camps across occupied Asia.

Why Nanking matters in AP World

Nanking lives in Unit 7 (Global Conflict, 1900-Present), Topic 7.8, and supports learning objective AP World 7.8.A, which asks you to explain the causes and consequences of mass atrocities from 1900 to the present. The CED's essential knowledge points to extremist ideologies in power driving the attempted destruction of specific populations, and Nanking is a textbook case. Japanese ultranationalism and imperial ideology dehumanized the Chinese population, and that dehumanization turned a military conquest into a mass atrocity. Nanking also matters because it widens your evidence base beyond Europe. If every example you bring to an essay is the Holocaust, you're missing the global pattern the course is built around. Nanking lets you show that mass violence against civilians in this era happened across multiple continents and ideologies, which is exactly the kind of broad, comparative thinking LEQs and DBQs reward.

How Nanking connects across the course

Second Sino-Japanese War (Unit 7)

Nanking happened in the opening months of this war, which began in 1937 and later merged into World War II. The massacre shows how Japan's invasion of China was already total war against civilians two years before fighting started in Europe.

War Crimes (Unit 7)

Nanking is one of the clearest examples of war crimes in the 20th century, and Japanese commanders were prosecuted for it at the postwar Tokyo trials. It pairs with the Nuremberg trials as evidence that WWII pushed the world toward holding individuals legally responsible for atrocities.

The Holocaust and extremist ideology (Unit 7)

Both Nanking and the Holocaust came from the same root the CED highlights, extremist regimes in power dehumanizing a target population. Comparing them lets you argue that mass atrocity in this era wasn't one regime's aberration but a pattern produced by ultranationalism and total war.

Armenian Genocide (Unit 7)

Like Nanking, the Armenian Genocide shows civilians targeted under the cover of a larger war (World War I). Together they support a continuity argument that wartime conditions repeatedly gave states the opportunity and excuse to destroy populations.

Is Nanking on the AP World exam?

No released FRQ has used Nanking by name, but it earns its keep as evidence. Topic 7.8 questions ask you to explain causes and consequences of mass atrocities, and Nanking works as outside evidence in a DBQ on global conflict or as one half of a comparison in an LEQ. Practice questions on this topic ask things like how Japanese war crimes in Nanking mirrored Nazi atrocities, and how Japanese imperialism before and during WWII produced mass atrocities. So the move you need to make is causal and comparative, not just descriptive. Don't stop at "Nanking was a massacre." Connect it upstream to Japanese imperial expansion and ultranationalist ideology, and sideways to other atrocities like the Holocaust or the Armenian Genocide, to show the global pattern.

Nanking vs Nagasaki

The names sound similar but these are completely different events on opposite sides of the war. Nanking is a Chinese city where the Japanese army massacred Chinese civilians in 1937-1938. Nagasaki is a Japanese city the United States destroyed with an atomic bomb in August 1945. Nanking belongs in a mass-atrocities argument (Topic 7.8); Nagasaki belongs in discussions of total war technology and the end of WWII. Mixing them up in an essay signals you don't know who did what to whom.

Key things to remember about Nanking

  • Nanking (Nanjing) was the Chinese Nationalist capital captured by Japan in December 1937, and the massacre that followed killed hundreds of thousands of Chinese civilians.

  • The massacre happened during the Second Sino-Japanese War, which began in 1937 and merged into World War II.

  • For Topic 7.8 and learning objective AP World 7.8.A, Nanking is evidence that extremist nationalist ideology and imperial expansion caused mass atrocities against civilians.

  • Nanking pairs well with the Holocaust, the Armenian Genocide, and the Cambodian Genocide in comparative essays because all show states or regimes targeting specific populations during the 20th century.

  • Japanese forces in occupied Asia also ran forced labor camps and the comfort women system, so Nanking fits a broader pattern of Japanese wartime atrocities, not an isolated event.

  • Don't confuse Nanking (Japanese atrocity in China, 1937) with Nagasaki (US atomic bombing of Japan, 1945).

Frequently asked questions about Nanking

What was the Nanking Massacre in AP World History?

The Nanking Massacre (also called the Rape of Nanking) was the mass killing, torture, and sexual assault of Chinese civilians and prisoners by the Imperial Japanese Army after it captured the Chinese capital of Nanjing in December 1937. Death toll estimates reach as high as 300,000, and it's a major example for Topic 7.8, Mass Atrocities After 1900.

Did the Nanking Massacre happen during World War II?

Technically it started before WWII began in Europe. The massacre occurred in 1937-1938 during the Second Sino-Japanese War, two years before Germany invaded Poland in 1939. That war later merged into WWII, which is why Nanking is usually discussed alongside WWII atrocities.

How is Nanking different from Nagasaki?

Nanking is a Chinese city where Japanese forces massacred Chinese civilians in 1937-1938. Nagasaki is a Japanese city the United States hit with an atomic bomb in August 1945. Different countries, different victims, different parts of the exam.

Is the Nanking Massacre considered a genocide?

It's usually classified as a mass atrocity and war crime rather than a genocide, since genocide refers to the attempted destruction of an entire group. Japanese commanders were prosecuted for it at the postwar Tokyo war crimes trials. On the exam, it fits the CED's broader category of atrocities and ethnic violence under learning objective AP World 7.8.A.

Is Nanking on the AP World exam?

Nanking isn't one of the CED's named illustrative examples for Topic 7.8, but it's fair game and a strong piece of evidence. Multiple-choice and short-answer questions on mass atrocities often use it, and it works well as outside evidence in DBQs and LEQs about global conflict and 20th-century violence against civilians.
