States may make alliances out of self-interest, fear, or ideology. The ensuing relationships are rarely easy, however, especially when put to the test of war. Alliances can either make and keep the peace, or they can lead to conflict. In so doing, they have helped to shape, for better or worse, the modern world. This series of lectures examines the nature, dynamics, and types of alliances, suggesting reasons why they either succeed or fail. While alliances have been a feature of state-to-state relations since the ancient world, the main focus of these lectures will be on the 20th century – in particular, the great global conflicts of the First and Second World Wars.
The Grand Alliance between the Big Three – the British Empire, the Soviet Union and the United States – emerged through total war, and each power had its own specific aims and concerns. This final lecture examines the tensions in forging Allied strategy and the planning of the post-war world, asking whether the Grand Alliance could have survived the end of the war or whether the Cold War was indeed inevitable.
