International Relations, 1919–29 | Cambridge AS History 9489 | Unit 8 Complete Bundle

The decade after the First World War moved from bitter disagreement over the peace settlement to renewed crises, diplomatic experimentation and, eventually, an apparent period of international cooperation. This complete Cambridge International AS Level History (9489) Unit 8 bundle brings together all four curriculum enquiries: 8.1 dissatisfaction with the peace settlements of 1919–20; 8.2 the creation of the League of Nations and its challenges in the 1920s; 8.3 continuing international tensions after Versailles; and 8.4 the improvement of international relations between 1924 and 1929. Across the four presentations, students encounter the major issues and developments shaping the decade: the post-war peace treaties and reparations, the League of Nations and collective security, Fiume, Corfu and the Ruhr crisis, the problems of the successor states, the Dawes and Young Plans, Locarno, the Kellogg-Briand Pact and other attempts to build a more stable international order. Importantly, the resources help students connect these events rather than study them in isolation—showing how economic pressures, nationalism, security concerns, great-power interests and diplomacy shaped international relations throughout the 1920s. Together, the four resources provide a coherent teaching sequence for the entire International Relations, 1919–29 unit. Detailed historical knowledge is consistently connected to causation, comparison, significance and supported judgement, making the bundle valuable for classroom teaching, revision, independent study and Cambridge exam preparation. For teachers, it offers a substantial ready-to-use foundation for the whole unit; for students, it builds the understanding needed to judge whether the apparent international stability achieved by 1929 represented genuine progress—or a fragile peace vulnerable to the pressures ahead.
