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.
Allied war crimes during World War IIDuring World War II, the Allies committed legally proven war crimes and violations of the laws of war against either civilians or military personnel of the Axis powers. At the end of World War II, many trials of Axis war criminals took place, most famously the Nuremberg Trials and Tokyo Trials. In Europe, these tribunals were set up under the authority of the London Charter, which only considered allegations of war crimes committed by people who acted in the interests of the Axis powers.
Soviet war crimesThe war crimes and crimes against humanity which were perpetrated by the Soviet Union and its armed forces from 1919 to 1991 include acts which were committed by the Red Army (later called the Soviet Army) as well as acts which were committed by the country's secret police, NKVD, including its Internal Troops. In many cases, these acts were committed upon the orders of the Soviet leaders Vladimir Lenin and Joseph Stalin in pursuance of the early Soviet government's policy of Red Terror.
Italian war crimesItalian war crimes have mainly been associated with Fascist Italy in the Pacification of Libya, the Second Italo-Ethiopian War, the Spanish Civil War, and World War II. In 1911, Italy went to war with the Ottoman Empire and invaded Ottoman Tripolitania. One of the most notorious incidents during this conflict was the October Tripoli massacre, wherein many civilian inhabitants of the Mechiya oasis were killed over a period of three days as retribution for the execution and mutilation of Italian captives taken in an ambush at nearby Sciara Sciat.
