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 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.

World War II or the Second World War was a global conflict between two major alliances: the Allies and the Axis powers. The vast majority of the world's countries, including all the great powers, fought as part of these military alliances. Many participating countries invested all available economic, industrial, and scientific capabilities into this total war, blurring the distinction between civilian and military resources. Aircraft played a major role, enabling the strategic bombing of population centres and delivery of the only two nuclear weapons ever used in war. It was by far the deadliest conflict in history, resulting in 70–85 million fatalities. Millions died due to genocides, including the Holocaust, as well as starvation, massacres, and disease. In the wake of Axis defeat, Germany, Austria, and Japan were occupied, and war crime tribunals were conducted against German and Japanese leaders.
The Axis powers, originally called the Rome–Berlin Axis and also Rome–Berlin–Tokyo Axis, was a military coalition that initiated World War II and fought against the Allies. Its principal members were Nazi Germany, the Kingdom of Italy and the Empire of Japan. The Axis were united in their far-right positions and general opposition to the Allies, but otherwise lacked comparable coordination and ideological cohesion.
In World War II, the Polish armed forces were the fourth largest Allied forces in Europe, after those of the Soviet Union, United States, and Britain.[a] Poles made substantial contributions to the Allied effort throughout the war, fighting on land, sea, and in the air.
The Invasion of Poland, also known as the September Campaign, Polish Campaign, War of Poland of 1939, and Polish Defensive War of 1939, was a joint attack on the Republic of Poland by Nazi Germany, the Slovak Republic, and the Soviet Union; which marked the beginning of World War II. The German invasion began on 1 September 1939, one week after the signing of the Molotov–Ribbentrop Pact between Germany and the Soviet Union, and one day after the Supreme Soviet of the Soviet Union had approved the pact. The Soviets invaded Poland on 17 September. The campaign ended on 6 October with Germany and the Soviet Union dividing and annexing the whole of Poland under the terms of the German–Soviet Frontier Treaty. The invasion is also known in Poland as the September campaign or 1939 defensive war and known in Germany as the Poland campaign.
The European theatre of World War II was one of the two main theatres of combat during World War II. It saw heavy fighting across Europe for almost six years, starting with Germany's invasion of Poland on 1 September 1939 and ending with the Western Allies conquering most of Western Europe, the Soviet Union conquering most of Eastern Europe including the German capital Berlin, and Germany's unconditional surrender on 8 May 1945 although fighting continued elsewhere in Europe until 25 May. On 5 June 1945, the Berlin Declaration proclaiming the unconditional surrender of Germany to the four victorious powers was signed. The Allied powers fought the Axis powers on two major fronts, but there were other fronts varying in scale from the Italian campaign, to the Polish Campaign, as well as in a strategic bombing offensive and in the adjoining Mediterranean and Middle East theatre.
The Eastern Front was a theatre of World War II fought between the European Axis powers and Allies, including the Soviet Union (USSR) and Poland. It encompassed Central Europe, Eastern Europe, Northeast Europe (Baltics), and Southeast Europe (Balkans), and lasted from 22 June 1941 to 9 May 1945. Of the estimated 70–85 million deaths attributed to World War II, around 30 million occurred on the Eastern Front, including 9 million children. The Eastern Front was decisive in determining the outcome in the European theatre of operations in World War II, eventually serving as the main reason for the defeat of Nazi Germany and the Axis nations. It is noted by historian Geoffrey Roberts that "More than 80 percent of all combat during the Second World War took place on the Eastern Front".
The causes of World War II have been given considerable attention by historians. The immediate precipitating event was the invasion of Poland by Nazi Germany on September 1, 1939, and the subsequent declarations of war on Germany made by Britain and France, but many other prior events have been suggested as ultimate causes. Primary themes in historical analysis of the war's origins include the political takeover of Germany in 1933 by Adolf Hitler and the Nazi Party; Japanese militarism against China, which led to the Japanese invasion of Manchuria and the Second Sino-Japanese War; Nationalist uprising in Spain, which led to the Spanish Civil War; or Italian aggression against Ethiopia, which led to the Second Italo-Ethiopian War.
Almost every country in the world participated in World War II. Most were neutral at the beginning, but only a relative few nations remained neutral to the end. The Second World War pitted two alliances against each other, the Axis powers and the Allied powers. It is estimated that 74 million people died, with estimates ranging from 40 million to 90 million dead. The leading Axis powers were Nazi Germany, the Empire of Japan and the Kingdom of Italy; while the British Empire, the United States, the Soviet Union and China were the "Big Four" Allied powers.
This timeline of events preceding World War II covers the events that affected or led to World War II.
The Allies, formally referred to as the United Nations from 1942, were an international military coalition formed during World War II (1939–1945) to oppose the Axis powers. Its principal members by the end of 1941 were the "Big Four" – United Kingdom, United States, Soviet Union, and China.
During World War II, resistance movements operated in German-occupied Europe by a variety of means, ranging from non-cooperation to propaganda, hiding crashed pilots and even to outright warfare and the recapturing of towns. In many countries, resistance movements were sometimes also referred to as The Underground.
The following events occurred in August 1944:
The Allied leaders of World War II listed below comprise the important political and military figures who fought for or supported the Allies during World War II. Engaged in total war, they had to adapt to new types of modern warfare, on the military, psychological and economic fronts.
The Axis leaders of World War II were important political and military figures during World War II. The Axis was established with the signing of the Tripartite Pact in 1940 and pursued a strongly militarist and nationalist ideology; with a policy of anti-communism. During the early phase of the war, puppet governments were established in their occupied nations. When the war ended, many of them faced trial for war crimes. The chief leaders were Adolf Hitler of Nazi Germany, Benito Mussolini of Fascist Italy, and Hirohito of Imperial Japan. Unlike what happened with the Allies, there was never a joint meeting of the main Axis heads of government, although Mussolini and Hitler met on a regular basis.

This is a timeline of events that occurred during World War II in 1943.
The foreign relations of Third Reich were characterized by the territorial expansionist ambitions of Germany's dictator Adolf Hitler and the promotion of the ideologies of anti-communism and antisemitism within Germany and its conquered territories. The Nazi regime oversaw Germany's rise as a militarist world power from the state of humiliation and disempowerment it had experienced following its defeat in World War I. From the late 1930s to its defeat in 1945, Germany was the most formidable of the Axis powers - a military alliance between Imperial Japan, Fascist Italy, and their allies and puppet states. Adolph Hitler made most of the major diplomatic policy decisions, while foreign minister Konstantin von Neurath handled routine business.
