January 28 incidentThe January 28 incident or Shanghai incident (January 28 – March 3, 1932) was a conflict between the Republic of China and the Empire of Japan. It took place in the Shanghai International Settlement which was under international control. Japanese army officers, defying higher authorities, had provoked anti-Japanese demonstrations in the International Settlement following the Japanese invasion of Manchuria. The Japanese government sent a sect of militant ultranationalist Japanese Buddhist priests belonging to the Nichiren sect to Shanghai.
Atomic bombings of Hiroshima and NagasakiOn 6 and 9 August 1945, the United States detonated two atomic bombs over the Japanese cities of Hiroshima and Nagasaki. The bombings killed between 129,000 and 226,000 people, most of whom were civilians, and remain the only use of nuclear weapons in an armed conflict. Japan surrendered to the Allies on 15 August, six days after the bombing of Nagasaki and the Soviet Union's declaration of war against Japan and invasion of Japanese-occupied Manchuria. The Japanese government signed the instrument of surrender on 2 September, effectively ending the war.
Suicide attackA suicide attack is any violent attack, usually entailing attackers detonating an explosive, where any attackers have accepted their own death as a direct result of the attacking method used. Suicide attacks have occurred throughout history, often as part of a military campaign (as with the Japanese kamikaze pilots of 1944–1945 during World War II), and more recently as part of Islamic terrorist campaigns (such as the September 11 attacks in 2001).
Second Sino-Japanese WarThe Second Sino-Japanese War was a military conflict primarily between the Republic of China and the Empire of Japan from 1937 to 1945, as part of World War II. In China, the war is called the War of Resistance against Japanese Aggression (). This total war between China and the Empire of Japan is often regarded as the beginning of World War II in Asia, although some scholars consider the European War and the Pacific War to be entirely separate, albeit concurrent.
Japanese war crimesThe Empire of Japan committed war crimes and crimes against humanity in many Asian-Pacific countries during the period of Japanese imperialism, primarily during the Second Sino-Japanese and Pacific Wars. These incidents have been described as "the Asian Holocaust". Some war crimes were committed by Japanese military personnel during the late 19th century, but most were committed during the first part of the Shōwa era, the name given to the reign of Emperor Hirohito.
Interwar periodIn the history of the 20th century, the interwar period (or interbellum) lasted from 11November 1918 to 1September 1939 (20years, 9months, 21 days)the end of the First World War to the beginning of the Second World War. The interwar period was relatively short, yet featured many significant social, political, and economic changes throughout the world. Petroleum-based energy production and associated mechanisation led to the prosperous Roaring Twenties, a time of both social mobility and economic mobility for the middle class.
