Was the Treaty of Versailles fair?

The treaty was signed on 28 June 1919. The Big Three wanted different things: Clemenceau (France) wanted Germany crippled; Wilson (USA) wanted his Fourteen Points and a League of Nations; Lloyd George (Britain) wanted German trade to survive but faced voters who wanted revenge.

Main terms:

• War guilt (Article 231) — Germany accepted blame for the war.
• Reparations — fixed in 1921 at £6,600 million.
• Armed forces — army capped at 100,000, no air force, no submarines, six battleships; the Rhineland demilitarised.
• Territory — Alsace-Lorraine to France, the Saar under League control for 15 years, land to Poland, all colonies taken as mandates; Anschluss with Austria forbidden.

Impact by 1923: Germans called it a Diktat. When Germany fell behind with reparations, French and Belgian troops occupied the Ruhr (1923); passive resistance and government printing produced hyperinflation.

The most resented clause

To what extent was the League of Nations a success?

The League had an Assembly, a Council, a Secretariat, a Permanent Court and agencies. Its weaknesses were built in: the USA never joined, Germany and the USSR were initially excluded, it had no army, and decisions in the Council needed unanimity.

• 1920s successes: the Aaland Islands (1920–21) and Bulgaria (1925) — small disputes settled.
• 1920s failures: Vilna (1920) and Corfu (1923) — when a Great Power (Poland, Italy) defied it, the League was powerless.
• Humanitarian work — refugees, health, working conditions and the campaign against slavery: a genuine and lasting success.
• 1930s collapse: the Manchurian crisis (1931–33) — Japan ignored the Lytton Report and left the League; the Abyssinian crisis (1935–36) — sanctions were half-hearted and the Hoare–Laval Pact discredited Britain and France.

The Depression mattered: economic collapse after 1929 made countries selfish. They wanted trade, empires and jobs — not collective security.

Why was the League weak?

Hitler's foreign policy and appeasement

Hitler aimed to destroy Versailles, unite German speakers and win Lebensraum in the east. Step by step:

• 1935 — the Saar plebiscite returned the Saar to Germany; conscription and rearmament announced; the Anglo-German Naval Agreement.
• 1936 — troops remilitarised the Rhineland; the Rome–Berlin Axis and the Anti-Comintern Pact; German and Italian intervention in the Spanish Civil War.
• 1938 — Anschluss with Austria (March); the Czech crisis and the Munich Agreement (September), which handed Germany the Sudetenland.
• 1939 — Hitler took the rest of Czechoslovakia (March); the Nazi–Soviet Pact (23 August); the invasion of Poland (1 September). Britain and France declared war on 3 September 1939.

Was appeasement justified? Arguments for: Britain was unready to fight, the public feared bombing, many thought Versailles unfair, and the USSR was distrusted. Arguments against: it fed Hitler's appetite, betrayed Czechoslovakia, and gave Germany time to rearm.

Sort the Cold War flashpoints

Tap an event, then tap the decade it belongs to.

Who was to blame for the Cold War?

The wartime alliance broke down fast. At Yalta (February 1945) the Allies agreed to divide Germany and hold free elections in Eastern Europe; by Potsdam (July–August 1945) trust had evaporated — Roosevelt had died, the atomic bomb had been tested, and Soviet troops occupied Eastern Europe.

• Soviet expansion: communist governments were installed across Eastern Europe by 1948. Churchill's Iron Curtain speech came in March 1946.
• American reaction: the Truman Doctrine (containment) and the Marshall Plan (economic aid), both 1947.
• Berlin: Stalin's blockade (June 1948 – May 1949) was answered by the airlift. Result: two Germanies, and the founding of NATO in 1949. The Warsaw Pact followed in 1955.

How effectively did the USA contain communism?

Cambridge tests three case studies.

• Korea, 1950–53: North Korea invaded the South in June 1950. The USA led a UN force (the USSR was boycotting the Security Council). MacArthur pushed to the Chinese border; China intervened; an armistice in 1953 left the border roughly at the 38th parallel. Containment held — at heavy cost.
• Cuba, 1959–62: Castro's revolution, the failed Bay of Pigs invasion (1961), then the Cuban Missile Crisis (October 1962). Kennedy imposed a naval blockade; Khrushchev removed the missiles in return for a US pledge not to invade Cuba (and the quiet removal of US missiles from Turkey). Cuba stayed communist.
• Vietnam, 1955–75: the USA escalated after the Gulf of Tonkin incident (1964). Despite huge firepower, the Tet Offensive (1968) shattered US confidence. The USA withdrew after the Paris Peace Accords (1973); Saigon fell in 1975. Containment failed.

Judging containment

How secure was the USSR's control, 1948–c.1989?

Soviet control was repeatedly challenged — and, until 1989, repeatedly reimposed by force.

• Hungary, 1956: Nagy promised free elections and withdrawal from the Warsaw Pact. Soviet tanks crushed the rising; Nagy was later executed.
• Berlin Wall, 1961: built to stop the flood of skilled workers escaping to the West through Berlin — a propaganda disaster that nonetheless worked.
• Czechoslovakia, 1968: Dubček's "socialism with a human face" (the Prague Spring) ended with a Warsaw Pact invasion and the Brezhnev Doctrine.
• Poland, 1980–81: Solidarity, led by Lech Wałęsa, became a mass free trade union; martial law was declared in December 1981, but Solidarity survived underground.
• Gorbachev: glasnost and perestroika, and his refusal to send tanks, let the satellite regimes fall in 1989. The Berlin Wall opened on 9 November 1989.

Paper 1 and Paper 2 in Option B

Structured questions usually come in three parts: describe (recall), explain why (causation) and how far do you agree (judgement).

• For "explain why", give developed reasons: point → precise evidence → link back to the question.
• For "how far", argue both sides and then decide. E.g. "Hitler's foreign policy was the main cause of war in 1939, but appeasement and the failures of the League made his gambles safe."
• Paper 2 is a source paper: use provenance (who wrote it, when, why) as well as content.

Reading a source

From one peace to another

Option B tells one long story about collective security:

• 1919–23: a peace many Germans rejected, and a League built without the USA.
• 1931–39: aggressors (Japan, Italy, Germany) tested the system; it failed, and appeasement bought time rather than peace.
• 1945–89: two superpowers replaced collective security with deterrence and blocs — NATO and the Warsaw Pact — until Soviet control collapsed from within.

The Nazi–Soviet Pact

Who was to blame? Three interpretations

Cambridge wants you to handle interpretations:

• Blame the USSR: Stalin broke the Yalta promise of free elections, imposed communist regimes and blockaded Berlin.
• Blame the USA: the atomic bomb, the Truman Doctrine and the Marshall Plan looked to Moscow like an attempt to dominate Europe economically and militarily.
• Blame neither alone: deep ideological difference plus mutual fear and misreading after 1945 made confrontation almost inevitable.
