Operation Barbarossa was the invasion of the Soviet Union by Nazi Germany and many of its Axis allies, starting on Sunday, 22 June 1941, during the Second World War. It was the largest land offensive in human history, with around 10 million combatants taking part. The operation, code-named after Frederick Barbarossa, a 12th-century Holy Roman Emperor and Crusader, put into action Nazi Germany's ideological goal of conquering the western Soviet Union to repopulate it with Germans. The German Generalplan Ost aimed to use some of the conquered people as forced labour for the Axis war effort while acquiring the oil reserves of the Caucasus as well as the agricultural resources of various Soviet territories, including Ukraine and Byelorussia. Their ultimate goal was to create more Lebensraum for Germany, and the eventual extermination of the native Slavic peoples by mass deportation to Siberia, Germanisation, enslavement, and genocide.
World War II or the Second World War was a global conflict that lasted from 1939 to 1945. The vast majority of the world's countries, including all the great powers, fought as part of two opposing military alliances: the Allies and the Axis. 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, 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.
Western betrayal is the view that the United Kingdom, France, and sometimes the United States failed to meet their legal, diplomatic, military, and moral obligations with respect to the Czechoslovak and Polish states during the prelude to and aftermath of World War II. It also sometimes refers to the treatment of other Central and Eastern European states at the time.
Military production during World War II was the production or mobilization of arms, ammunition, personnel and financing by the belligerents of the war, from the occupation of Austria in early 1938 to the surrender and occupation of Japan in late 1945.
The Mediterranean and Middle East Theatre was a major theatre of operations during the Second World War. The vast size of the Mediterranean and Middle East theatre saw interconnected naval, land, and air campaigns fought for control of the Mediterranean, North Africa, the Horn of Africa, the Middle East and Southern Europe. The fighting lasted from 10 June 1940, when Italy entered the war on the side of Germany, until 2 May 1945 when all Axis forces in Italy surrendered. However, fighting would continue in Greece – where British troops had been dispatched to aid the Greek government – during the early stages of the Greek Civil War.
The term "home front" covers the activities of the civilians in a nation at war. World War II was a total war; homeland military production became vital to both the Allied and Axis powers. Life on the home front during World War II was a significant part of the war effort for all participants and had a major impact on the outcome of the war. Governments became involved with new issues such as rationing, manpower allocation, home defense, evacuation in the face of air raids, and response to occupation by an enemy power. The morale and psychology of the people responded to leadership and propaganda. Typically women were mobilized to an unprecedented degree.
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.

This is a timeline of events of World War II in 1939, from the start of the war on 1 September 1939. For events preceding September 1, 1939, see the timeline of events preceding World War II.
Hans Krebs was a German Army general of infantry who served during World War II. A career soldier, he served in the Reichswehr and the Wehrmacht. He served as the last Chief of Staff of the Oberkommando des Heeres (OKH) during the final phase of the war in Europe. Krebs tried to open surrender negotiations with the Red Army; he committed suicide in the Führerbunker during the early hours of 2 May 1945, two days after Adolf Hitler killed himself.
When the United Kingdom declared war on Nazi Germany in September 1939 at the start of World War II, it controlled to varying degrees numerous crown colonies, protectorates, and India. It also maintained unique political ties to four of the five independent Dominions—Australia, Canada, South Africa, and New Zealand—as co-members of the then "British Commonwealth". In 1939 the British Empire and the Commonwealth together comprised a global power, with direct or de facto political and economic control of 25% of the world's population, and of 30% of its land mass.
The Wehrmacht were the unified armed forces of Nazi Germany from 1935 to 1945. It consisted of the Heer (army), the Kriegsmarine (navy) and the Luftwaffe. The designation "Wehrmacht" replaced the previously used term Reichswehr and was the manifestation of the Nazi regime's efforts to rearm Germany to a greater extent than the Treaty of Versailles permitted.
After the Munich Agreement, the Soviet Union pursued a rapprochement with Nazi Germany. On 23 August 1939 the Soviet Union signed a non-aggression pact with Germany which included a secret protocol that divided Eastern Europe into German and Soviet "spheres of influence", anticipating potential "territorial and political rearrangements" of these countries. Germany invaded Poland on 1 September 1939, starting World War II. The Soviets invaded eastern Poland on 17 September. Following the Winter War with Finland, the Soviets were ceded territories by Finland. This was followed by annexations of the Baltic states and parts of Romania.
Military intelligence on the V-1 and V-2 weapons developed by the Germans for attacks on the United Kingdom during the Second World War was important to countering them. Intelligence came from a number of sources and the Anglo-American intelligence agencies used it to assess the threat of the German V-weapons.
Convoy PQ 18 was the last of the PQ/QP series of arctic convoys during World War II, bound from US and British ports via Reykjavík in Iceland to the Barents Sea and White Sea ports of the Soviet Union, particularly Murmansk and Archangel. The convoy sailed on 2 September 1942 and arrived three weeks later on 21 September 1942. It was opposed by German sea and air forces based in occupied Norway.

This list aims to include memoirs written by participants of World War II about their wartime experience, as well as larger autobiographies of participants of World War II that are at least partially concerned with the author's wartime experience.
