International Relations: the changing international order 1918–1975 with Germany 1925–1955

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 the League of Nations, the causes of World War II, the Cold War, and decolonisation. It also examines Germany's turbulent journey from the Weimar Republic through Nazi dictatorship to division into East and West Germany. Understanding this period is crucial because it explains how the world moved from a multipolar to a bipolar order, and how Germany's position in Europe shaped global conflicts.

The OCR GCSE specification requires you to analyse key events such as the Treaty of Versailles (1919), the League of Nations' failures in the 1930s, the origins of the Cold War (1945–1949), and the Berlin Blockade (1948–49). For Germany, you need to know the impact of the Great Depression on the Weimar Republic, Hitler's foreign policy (e.g., remilitarisation of the Rhineland, Anschluss), and the division of Germany after 1945. This topic is essential because it links domestic German history with international relations, showing how internal politics can trigger global change.

By studying this period, you'll understand key concepts like collective security, appeasement, spheres of influence, and the nuclear arms race. The OCR exam often asks you to evaluate the effectiveness of international organisations (e.g., League of Nations vs. UN) and to explain why Germany became a flashpoint in the Cold War. Mastering this topic will help you write analytical essays that connect events across time and space, a skill vital for top marks.
