20th Century Ideas

The ideological movements and intellectual frameworks that drove the century’s politics — fascism, Stalinism, social democracy, neoliberalismMonetarism Monetarism is the economic school of thought associated with Milton Friedman, which rose to dominance as a counter to Keynesian economics. It posits that inflation is always a monetary phenomenon and that the government’s role should be limited to managing the currency rather than stimulating demand. Key Mechanisms: Inflation Targeting: Using interest rates to keep inflation low, even if high interest rates cause recession or unemployment. Fiscal Restraint: Opposing government deficit spending to boost the economy during downturns. Critical Perspective:Critics argue that monetarism breaks the post-war social contract. By prioritizing “sound money” and low inflation above all else, monetarist policies often induce deliberately high unemployment to discipline the labor force and suppress wages. It represents a technical solution to political problems, removing economic policy from democratic accountability. , anticolonialism, and more.

20th Century Interpretations

The major historiographical debates — intentionalism vs functionalism, Cold WarCold War The geopolitical and ideological confrontation between the United States and the Soviet Union that dominated global politics from 1947 to 1991. It was fought not through direct military conflict between the superpowers but through proxy wars, arms races, espionage, and ideological competition across the developing world. The Cold War began before the Second World War had fully ended: American and Soviet disagreements over the post-war order in Europe were visible at Yalta in February 1945 and had hardened into open confrontation by 1947, when the Truman Doctrine committed the United States to resisting Soviet expansion and the Marshall Plan began binding Western Europe to American economic leadership. The term itself was popularised by journalist Walter Lippmann in 1947, capturing the essential quality of a conflict that neither side could allow to become hot — because both possessed nuclear weapons capable of annihilating the other’s cities. The resulting stalemate was managed through deterrence, alliance systems (NATO in the West, the Warsaw Pact in the East), and the deliberate avoidance of direct superpower confrontation even while both sides fought intense proxy wars in Korea, Vietnam, Angola, Afghanistan, and dozens of other theatres. The Cold War was simultaneously a strategic competition and an ideological one: each side claimed to represent the future of humanity, and each used development aid, propaganda, cultural diplomacy, and covert action to advance its model in the non-aligned world. It ended not with a military defeat but with the internal collapse of the Soviet system between 1989 and 1991. The Cold War’s most important characteristic was its globality: what began as a European dispute about occupation zones became a worldwide competition that shaped the politics of every continent. For the United States, it justified interventions that overthrew democratic governments (Iran 1953, Guatemala 1954, Chile 1973) on the grounds that any leftist government was a Soviet beachhead; for the Soviet Union, it justified the crushing of reform movements within its own bloc (Hungary 1956, Czechoslovakia 1968) on the grounds that any deviation threatened the socialist camp. The Cold War’s legacy is therefore not only the fall of the Berlin Wall but the long list of democracies destroyed, developmental alternatives foreclosed, and civil wars fuelled in the name of containing the other side. The Third World paid the price for a confrontation between two powers that never actually fought each other. origins, Stalinist terror, decolonisation — built specifically to support AO3 across AQA, Edexcel, OCR, and WJEC.
