1937–1945 CE (full-scale resistance to Japan) / East Asia
Full-Scale Resistance to Japan and Civilians at War
After the Marco Polo Bridge Incident, the Sino-Japanese War became a full-scale conflict; military and civilian resistance, urban relocation, and severe wartime atrocities profoundly changed Chinese society.

The story
After the Marco Polo Bridge Incident in July 1937, Japan expanded its war of aggression against China, and China entered full-scale resistance. Nationalist government forces, armed groups led by the Communist Party, and people in different regions took part in resistance, while schools, factories, and residents relocated inland. After Nanjing fell in December 1937, Japanese troops committed large-scale killings, rape, and other atrocities known as the Nanjing Massacre. The war was both a military conflict and a process that caused enormous devastation to civilian lives, families, and social organizations. The map uses Marco Polo Bridge to mark the turning point into full-scale war; the period 1937–1945 does not include earlier resistance already underway in Northeast China and elsewhere.
Elsewhere in the world
After the Pacific War broke out in 1941, the Chinese theater became more closely connected with the global Allied war against the Axis powers.
