The story of the collapse of British Imperial Power. At the height of its power there was a popular saying that the sun never set on the British Empire. It was the largest Empire in history and was the world s foremost global power for over a century. In 1922, the British Empire ruled over a quarter of the world s population, comprising 458 million people. Yet despite being history s largest Empire at the start of the 20th century, the British Empire today is a shadow of its former self, with just 14 nations remaining under British sovereignty. What happened in those intervening years to cause the break-up of this once mighty realm? In the following three programmes we examine the factors that led to the British Empire dissolving. From the impact of the two World Wars to Gandhi s role in securing India s independence in 1947 and the damaging Suez Crisis, rarely seen footage from the Movietone archives provides a unique insight into The Fall of the British Empire.
