International Relations: the changing international order 1918–1975 with The USA 1919–1948

This topic explores the dramatic shifts in international relations from the end of World War I to the mid-1970s, focusing on the rise and fall of great powers, the impact of ideology, and the quest for collective security. It covers the failure of the League of Nations, the causes and consequences of World War II, the Cold War, and decolonisation. Understanding this period is crucial because it explains the origins of many contemporary global issues, such as nuclear proliferation, the Israeli-Palestinian conflict, and the role of international organisations like the UN.

Simultaneously, the USA 1919–1948 component examines America's transformation from isolationism to global superpower. Key themes include the economic boom of the 1920s, the Great Depression and New Deal, the social impact of World War II, and the early Cold War tensions. This dual focus allows students to see how domestic US policies influenced international relations and vice versa, providing a holistic view of the 20th-century world order.
