The global relations of power were altered fundamentally after the turbulent period between 1914 and 1945. In 1914, Britain was the world’s leading industrial state. She controlled the global infrastructure for trade and finance on which the world’s stability depended. Thirty years later in 1944 and 1945, Britain had lost nearly everything she had fought for over the previous 400 years. The USA took over global leadership. Worse, as far as Britain was concerned: she was about to lose control of her huge global empire and become again a small island nation in the North Atlantic.

The 30 years from 1914 to 1944 represent years of such death and turmoil at every level that it is hard to exaggerate the suffering across the globe. Many of the events of this period have become so seared into people’s memory, contemporary events are frequently compared and contrasted with them. More people than ever were involved in, or affected by war, and at the times when there was no war, there was chaos across the global economy, which affected everyone’s lives.

Following on from last week’s blog, a second possibility was that Germany was responsible for the war in 1914. All the winning powers agreed with this proposition in 1919. The new Germany was the "contending" nation for world power. In the 25 years before 1914, the German economy was growing significantly faster than Britain's. Germany had only been unified as a single state in 1870, and therefore had missed out in the race for colonies: the ‘common sense’ of European foreign policy of the era. And Germany was competing for oil, the new super energy in the ground in the Middle East.
