Beset by social and economic problems at home and challenging confrontations in the empire, Britain becomes involved in a second world-wide conflict.
Britain emerged into a new world when the war ended. The map of Europe was radically altered with the German and Austro-Hungarian empires replaced by new countries. In the East a strange new state, the Soviet Union, was being created to replace the Russian empire. Across the Atlantic, the United States was flexing its economic strength and, in the Pacific, Japan had taken its place alongside western industrial and military powers.
However, the British Empire still sprawled across the globe in many different forms. The dominions of Canada, Australia, New Zealand, Newfoundland and South Africa were self-governing entities, but they acknowledged the king as their ruler and took their forms of government and legal procedures from the British model.
