World War 1

The total number of casualties in World War I, both military and civilian, were about 37 million: 16 million deaths and 21 million wounded. The total number of deaths includes 9.7 million military personnel and about 6.8 million civilians. The Entente Powers (also known as the Allies) lost 5.7 million soldiers and the Central Powers about 4 million.

Classification of casualty statistics

Estimates of casualty numbers for World War I vary to a great extent; estimates of total deaths range from 9 million to over 16 million Military casualty statistics listed here include 6.8 million combat related deaths as well as 2 million military deaths caused by accidents, disease and deaths while prisoners of war. The table lists total deaths; the footnotes give a breakout between combat and non-combat losses. The figures listed below include about 6 million civilian deaths due to war related famine and disease, these civilian losses are often omitted from other compilations of World War I casualties. The war disrupted trade resulting in acute shortages of food which resulted in famine in Europe, the Ottoman Empire and Africa. Civilian deaths include the Armenian Genocide, and it is debated if this event should be included with war losses. Civilian deaths due to the Spanish flu have been excluded from these figures, whenever possible. Furthermore, the figures do not include deaths during the Turkish War of Independence and the Russian Civil War.

Atomic Bomb

The atomic bombings of Hiroshima and Nagasaki were nuclear attacks near the end of World War II against the Empire of Japan by the United States at the executive order of U.S. President Harry S. Truman on August 6 and 9, 1945. After six months of intense fire-bombing of 67 other Japanese cities, the nuclear weapon "Little Boy" was dropped on the city of Hiroshima on Monday,August 6, 1945, followed on August 9 by the detonation of the "Fat Man" nuclear bomb over Nagasaki. These are to date the only attacks with nuclear weapons in the history of warfare.

The bombs killed as many as 140,000 people in Hiroshima and 80,000 in Nagasaki by the end of 1945, roughly half on the days of the bombings. Amongst these, 15 to 20% died from injuries or illness attributed to radiation poisoning. Since then, more have died from leukemia (231 observed) and solid cancers (334 observed) attributed to exposure to radiation released by the bombs. In both cities, the overwhelming majority of the dead were civilians.

Six days after the detonation over Nagasaki, on August 15, Japan announced its surrender to the Allied Powers, signing the Instrument of Surrender on September 2, officially ending the Pacific War and therefore World War II. (Germany had signed its unavoidableInstrument of Surrender on May 7, ending the war in Europe.) The bombings led, in part, to post-war Japan adopting Three Non-Nuclear Principles, forbidding that nation from nuclear armament.
