International Relations: the changing international order 1918–1975 with The USA 1919–1948 exam tips
Topic Overview
This topic explores the shifting landscape of international relations from the end of World War I to the mid-1970s, with a particular focus on the role of the USA between 1919 and 1948. You will examine the collapse of old empires, the rise of new ideologies, and the attempts to create a stable world order through organisations like the League of Nations and the United Nations. The period covers the interwar years, World War II, and the early Cold War, highlighting how the USA transitioned from isolationism to global superpower.
Understanding this topic is crucial because it explains the origins of many contemporary global issues, such as the division of Europe, the nuclear arms race, and the role of international institutions. For the OCR GCSE, you need to analyse the causes and consequences of key events like the Treaty of Versailles, the Great Depression, the rise of fascism, and the breakdown of the Grand Alliance. The USA's journey from a reluctant participant in world affairs to a leading power is central to this narrative.
This topic fits into the wider subject of History by showing how international relations are shaped by economic pressures, ideological conflicts, and the actions of key individuals. It also connects to themes of power, diplomacy, and human rights, providing a foundation for understanding later developments such as the Cold War and decolonisation. Mastery of this period will help you evaluate historical interpretations and write analytical essays.
Key Concepts
- →Isolationism vs. Internationalism: The USA's shift from avoiding foreign entanglements in the 1920s to taking a leading role in global affairs after 1941, exemplified by the Lend-Lease Act and the Marshall Plan.
- →Collective Security: The idea that peace could be maintained through international cooperation, as attempted by the League of Nations (failed) and the United Nations (more successful initially).
- →Ideological Conflict: The clash between democracy, fascism, and communism, which drove alliances and tensions, especially the US-Soviet rivalry after 1945.
- →Economic Interdependence: How the Great Depression and trade policies (e.g., Smoot-Hawley Tariff) affected international relations, leading to protectionism and the rise of aggressive regimes.

Examiner Tips
- 💡Ensure you can link the impact of the war to broader themes of the US 1919-1948 depth study.
- 💡Be prepared to use primary source material to investigate the social impact of the war.
- 💡Focus on how the state's relationship with the people changed due to wartime requirements.
- 💡Use specific examples: When discussing US isolationism, mention the rejection of the Treaty of Versailles and the League of Nations, not just general statements. This shows detailed knowledge.
- 💡Link causes and consequences: For example, explain how the Treaty of Versailles caused resentment in Germany, which contributed to WWII, and how that led to the US becoming a superpower. This demonstrates analytical skills.
- 💡Evaluate interpretations: In essay questions, consider different historical perspectives (e.g., was the Cold War inevitable or due to US/Soviet actions?). This shows higher-level thinking.
Common Mistakes
- Misconception: The League of Nations was a complete failure. Correction: While it failed to prevent WWII, it had some successes in the 1920s (e.g., resolving the Åland Islands dispute) and laid the groundwork for the UN.
- Misconception: The USA was entirely isolationist until Pearl Harbor. Correction: The USA was involved in international affairs through the Washington Naval Conference (1921-22), the Kellogg-Briand Pact (1928), and the Good Neighbor Policy in Latin America.
- Misconception: The Cold War started immediately after WWII. Correction: Tensions grew gradually; the breakdown of the Grand Alliance occurred over issues like the future of Germany and Eastern Europe, with key events like the Truman Doctrine (1947) marking a clear shift.
Frequently Asked Questions
Why did the USA reject the Treaty of Versailles?
The USA rejected the Treaty of Versailles primarily due to concerns about the League of Nations. Many Americans, including influential senators like Henry Cabot Lodge, feared that joining the League would drag the USA into future wars and undermine its sovereignty. President Woodrow Wilson's refusal to compromise on the treaty's terms led to its defeat in the Senate. This decision marked a return to isolationism, which shaped US foreign policy until World War II.
How did the Great Depression affect international relations?
The Great Depression had a profound impact on international relations by causing economic nationalism and protectionism. Countries like the USA introduced high tariffs (e.g., Smoot-Hawley Tariff), which worsened global trade and led to retaliatory measures. This economic collapse fuelled political extremism, contributing to the rise of fascist regimes in Germany and Japan, who sought expansionist policies to secure resources. The depression also weakened the League of Nations, as member states focused on domestic issues rather than collective security.
What was the Lend-Lease Act and why was it important?
The Lend-Lease Act (1941) allowed the USA to supply Allied nations, particularly Britain and the Soviet Union, with war materials without immediate payment. It was important because it marked a shift from neutrality to active support for the Allies, effectively ending US isolationism. The act provided crucial aid that helped Britain survive the Blitz and the Soviet Union resist the German invasion, strengthening the Grand Alliance and paving the way for US entry into World War II after Pearl Harbor.
Why did the Grand Alliance break down after WWII?
The Grand Alliance between the USA, Britain, and the Soviet Union broke down due to ideological differences and conflicting post-war goals. The USSR wanted to create a buffer zone of friendly states in Eastern Europe, while the USA sought to promote democracy and open markets. Disagreements over the future of Germany, reparations, and the spread of communism led to increasing mistrust. Key events like the Truman Doctrine (1947) and the Berlin Blockade (1948-49) solidified the division into two hostile blocs, marking the start of the Cold War.
What was the Marshall Plan and how did it help the USA?
The Marshall Plan (1948-1951) was a US program that provided over $12 billion in economic aid to rebuild Western European economies after WWII. It helped the USA by creating stable, prosperous markets for American goods, thus preventing a post-war recession. Additionally, it countered the spread of communism by reducing poverty and political instability, which could have made countries vulnerable to Soviet influence. The plan also strengthened US alliances and established the USA as a leader in the Western bloc.
How did the USA become a superpower between 1919 and 1948?
The USA became a superpower through a combination of economic strength, military expansion, and diplomatic leadership. After WWI, the USA was already the world's largest economy, but it remained isolationist. During WWII, the US economy boomed as it supplied the Allies, and its military grew to become the most powerful in the world. The use of atomic bombs in 1945 demonstrated its technological superiority. After the war, the USA took on a leadership role through institutions like the UN, the Marshall Plan, and NATO, cementing its status as a global superpower.
