Outline of World War II

From Wikipedia, the free encyclopedia

The following outline is provided as an overview of and topical guide to World War II:

World War II, or the Second World War was a global military conflict that was fought between September 1, 1939 and September 2, 1945. The war was pitted two major military alliances against each other: the Allies of the United States, Soviet Union, United Kingdom, China and others against the Axis of Germany, Japan, Italy and others. Over 60 million people, the majority of them civilians, were killed, making it the deadliest conflict in human history.[1]

The Second World War was known for modern warfare and tactics such as air warfare, strategic bombing, blitzkrieg and the first, and only, use of nuclear weapons in warfare. It is also known for the numerous war crimes committed during its duration, mostly by Axis forces but also by Allied forces, that left tens of millions of civilians dead through genocides, massacres and starvation; such as the Holocaust, Three Alls Policy, Genocide of ethnic Poles, Unit 731, Nanjing massacre, Hunger Plan and the Warsaw Uprising.

  9. ^ The emperor was the titular leader of Japan and had the final say on decisions, but his power was still (somewhat) limited. The Prime Minister (Fumimaro Konoe and later Hideki Tojo for most of the war) held immense political power, and thus the emperor was not a dictator in the way Hitler or Mussolini were[2]
  10. ^ Victor Emmanuel III was the Italian head of state and did overrule Mussolini on certain occasions (such as refusing to join the Second World War until 1940 and even deposing him in 1943), but Mussolini used more de facto power and influence than the king
