World War II: Thirteen thousand British and French troops surrender to Major General Erwin Rommel at Saint-Valery-en-Caux.

Johannes Erwin Eugen Rommel (pronounced [vin ml] (listen)) (15 November 1891 14 October 1944) was a German field marshal during World War II. Popularly known as the Desert Fox (German: Wstenfuchs, pronounced [vystnfks] (listen)), he served in the Wehrmacht (armed forces) of Nazi Germany, as well as serving in the Reichswehr of the Weimar Republic, and the army of Imperial Germany.

Rommel was a highly decorated officer in World War I and was awarded the Pour le Mrite for his actions on the Italian Front. In 1937, he published his classic book on military tactics, Infantry Attacks, drawing on his experiences in that war. In World War II, he commanded the 7th Panzer Division during the 1940 invasion of France. His leadership of German and Italian forces in the North African campaign established his reputation as one of the ablest tank commanders of the war, and earned him the nickname der Wstenfuchs, "the Desert Fox". Among his British adversaries he had a reputation for chivalry, and his phrase "war without hate" has been uncritically used to describe the North African campaign. A number of historians have since rejected the phrase as myth and uncovered numerous examples of war crimes and abuses towards both enemy soldiers and native populations in Africa during the conflict. Other historians note that there is no clear evidence Rommel was involved or aware of these crimes, with some pointing out that the war in the desert, as fought by Rommel and his opponents, still came as close to a clean fight as there was in World War II. He later commanded the German forces opposing the Allied cross-channel invasion of Normandy in June 1944.

With the Nazis gaining power in Germany, Rommel gradually came to accept the new regime, with historians giving different accounts on the specific period and his motivations. He was a supporter of Adolf Hitler, at least until near the end of the war, if not necessarily sympathetic to the party and the paramilitary forces associated with it. In 1944, Rommel was implicated in the 20 July plot to assassinate Hitler. Because of Rommel's status as a national hero, Hitler desired to eliminate him quietly instead of immediately executing him, as many other plotters were. Rommel was given a choice between committing suicide, in return for assurances that his reputation would remain intact and that his family would not be persecuted following his death, or facing a trial that would result in his disgrace and execution; he chose the former and committed suicide using a cyanide pill. Rommel was given a state funeral, and it was announced that he had succumbed to his injuries from the strafing of his staff car in Normandy.

Rommel has become a larger-than-life figure in both Allied and Nazi propaganda, and in postwar popular culture, with numerous authors considering him an apolitical, brilliant commander and a victim of Nazi Germany, although this assessment is contested by other authors as the Rommel myth. Rommel's reputation for conducting a clean war was used in the interest of the West German rearmament and reconciliation between the former enemies the United Kingdom and the United States on one side and the new Federal Republic of Germany on the other. Several of Rommel's former subordinates, notably his chief of staff Hans Speidel, played key roles in German rearmament and integration into NATO in the postwar era. The German Army's largest military base, the Field Marshal Rommel Barracks, Augustdorf, is named in his honour. The longtime mayor of Stuttgart, Germany and namesake of Stuttgart Airport, Manfred Rommel, was his son.

World War II or the Second World War, often abbreviated as WWII or WW2, was a global war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. In a total war directly involving more than 100 million personnel from more than 30 countries, the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and the only two uses of nuclear weapons in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, a majority being civilians. Tens of millions of people died due to genocides (including the Holocaust), starvation, massacres, and disease. In the wake of the Axis defeat, Germany and Japan were occupied, and war crimes tribunals were conducted against German and Japanese leaders.

The exact causes of World War II are debated, but contributing factors included the Second Italo-Ethiopian War, the Spanish Civil War, the Second Sino-Japanese War, the Soviet–Japanese border conflicts and rising European tensions since World War I. World War II is generally considered to have begun on 1 September 1939, when Nazi Germany, under Adolf Hitler, invaded Poland. The United Kingdom and France subsequently declared war on Germany on 3 September. Under the Molotov–Ribbentrop Pact of August 1939, Germany and the Soviet Union had partitioned Poland and marked out their "spheres of influence" across Finland, Estonia, Latvia, Lithuania and Romania. From late 1939 to early 1941, in a series of campaigns and treaties, Germany conquered or controlled much of continental Europe, and formed the Axis alliance with Italy and Japan (along with other countries later on). Following the onset of campaigns in North Africa and East Africa, and the fall of France in mid-1940, the war continued primarily between the European Axis powers and the British Empire, with war in the Balkans, the aerial Battle of Britain, the Blitz of the UK, and the Battle of the Atlantic. On 22 June 1941, Germany led the European Axis powers in an invasion of the Soviet Union, opening the Eastern Front, the largest land theatre of war in history.

Japan, which aimed to dominate Asia and the Pacific, was at war with the Republic of China by 1937. In December 1941, Japan attacked American and British territories with near-simultaneous offensives against Southeast Asia and the Central Pacific, including an attack on the US fleet at Pearl Harbor which resulted in the United States declaring war against Japan. Therefore the European Axis powers declared war on the United States in solidarity. Japan soon captured much of the western Pacific, but its advances were halted in 1942 after losing the critical Battle of Midway; later, Germany and Italy were defeated in North Africa and at Stalingrad in the Soviet Union. Key setbacks in 1943—including a series of German defeats on the Eastern Front, the Allied invasions of Sicily and the Italian mainland, and Allied offensives in the Pacific—cost the Axis powers their initiative and forced it into strategic retreat on all fronts. In 1944, the Western Allies invaded German-occupied France, while the Soviet Union regained its territorial losses and turned towards Germany and its allies. During 1944 and 1945, Japan suffered reversals in mainland Asia, while the Allies crippled the Japanese Navy and captured key western Pacific islands.

The war in Europe concluded with the liberation of German-occupied territories, and the invasion of Germany by the Western Allies and the Soviet Union, culminating in the fall of Berlin to Soviet troops, Hitler's suicide and the German unconditional surrender on 8 May 1945. Following the Potsdam Declaration by the Allies on 26 July 1945 and the refusal of Japan to surrender on its terms, the United States dropped the first atomic bombs on the Japanese cities of Hiroshima, on 6 August, and Nagasaki, on 9 August. Faced with an imminent invasion of the Japanese archipelago, the possibility of additional atomic bombings, and the Soviet’s declared entry into the war against Japan on the eve of invading Manchuria, Japan announced on 15 August its intention to surrender, then signed the surrender document on 2 September 1945, cementing total victory in Asia for the Allies.

World War II changed the political alignment and social structure of the globe. The United Nations (UN) was established to foster international co-operation and prevent future conflicts, with the victorious great powers—China, France, the Soviet Union, the United Kingdom, and the United States—becoming the permanent members of its Security Council. The Soviet Union and the United States emerged as rival superpowers, setting the stage for the nearly half-century-long Cold War. In the wake of European devastation, the influence of its great powers waned, triggering the decolonisation of Africa and Asia. Most countries whose industries had been damaged moved towards economic recovery and expansion. Political and economic integration, especially in Europe, began as an effort to forestall future hostilities, end pre-war enmities and forge a sense of common identity.
