The Second World War (1939–1945) was the largest and deadliest conflict in history. It was fought across the world and touched almost every nation, ending in 1945.
A war across the world
Using fast-moving Blitzkrieg ("lightning war") tactics, Germany overran much of Europe by 1940. Key events in outline included:
- The Battle of Britain (1940), when the RAF defended Britain from air attack.
- Fighting in North Africa, where Allied and Axis armies fought for control of the desert.
- Germany's invasion of the Soviet Union in 1941, opening a vast Eastern Front.
- The Pacific war, which began when Japan attacked Pearl Harbor in December 1941, bringing the USA fully into the war.
Put these events of the Second World War in order, earliest first:
- Germany invades Poland, starting the war (September 1939)
- The Battle of Britain (1940)
- Germany invades the Soviet Union (1941)
- Japan attacks Pearl Harbor and the USA enters the war (December 1941)
- D-Day landings in Normandy (6 June 1944)
The Home Front
This was a "total war", involving whole societies, not just armies. On the Home Front, civilians faced air raids (in Britain, the Blitz), rationing of food and goods, evacuation of children to safer areas, and women taking on many jobs in factories and on the land.
The turning of the tide
- The Allies (chiefly Britain and its empire, the Soviet Union and the United States) gradually gained the upper hand from 1942–1943.
- On D-Day, 6 June 1944, Allied forces landed in Normandy in the largest seaborne invasion in history, beginning the liberation of occupied Western Europe.
On the Eastern Front, the vast battles between Germany and the Soviet Union, such as the fighting at Stalingrad, marked a decisive turning point at enormous cost.
The end of the war, 1945
Germany surrendered in May 1945 (marked as VE Day, Victory in Europe). The war in the Pacific ended later in 1945 (VJ Day). The immense loss of life led directly to the founding of the United Nations to help keep world peace.
The world emerged determined to build institutions that could prevent such a catastrophe from happening again.
