International Relations: the changing international order 1918–1975 with The USA 1945–1974

This topic explores the dramatic shifts in international relations from the end of World War I to the mid-1970s, focusing on the collapse of empires, the rise of new ideologies, and the emergence of a bipolar world. It covers the failure of the League of Nations, the causes and consequences of World War II, the Cold War, decolonisation, and the changing role of the USA as a global superpower. Understanding this period is crucial for grasping how the modern world order was shaped by conflict, diplomacy, and ideological rivalry.

The USA 1945–1974 section examines America's transformation from an isolationist power to the leader of the Western bloc. Key themes include the Truman Doctrine, the Marshall Plan, the Korean and Vietnam Wars, the Civil Rights Movement, and the presidencies of Truman, Eisenhower, Kennedy, Johnson, and Nixon. This period saw the USA confront both external communist threats and internal social upheaval, making it a pivotal era in American and world history.

Together, these topics allow students to analyse the interplay between superpower competition, decolonisation, and domestic change. By studying the successes and failures of international organisations, the impact of nuclear weapons, and the struggle for human rights, students gain a deeper understanding of the forces that continue to shape global politics today.
