Welcome to the Inter-War Years!

Hi there! Welcome to your study notes for History 8145: Conflict and Tension, 1918–1939. This chapter is all about the "messy middle"—the 21 years between the end of the First World War and the start of the Second. We are going to look at why peace was so hard to keep, how the world tried to prevent another war, and why it eventually failed. Think of it like a giant group project where nobody can agree on the rules, and eventually, the whole thing falls apart.

Don't worry if some of these names or treaties seem tricky at first. We’ll break them down into bite-sized pieces so you can master them for your exam!


Part One: Peacemaking (1918–1919)

After the fighting of WWI stopped with the Armistice, the winners met in Paris to decide what to do with Germany. This was the Treaty of Versailles.

The Big Three

Imagine three people trying to settle a playground fight. They all want different things:

1. Woodrow Wilson (USA): He wanted a "fair peace." He had Fourteen Points to make the world safer, including national self-determination (letting countries rule themselves) and setting up a League of Nations.
2. Georges Clemenceau (France): He was "The Tiger." France had suffered the most, so he wanted to crush Germany so they could never attack again.
3. David Lloyd George (Britain): He was stuck in the middle. He wanted to punish Germany (because the British public were angry), but he also wanted Germany to stay strong enough to trade with Britain.

The Terms of the Treaty: Remember "BRAT"

A great way to remember the main points of the Treaty of Versailles is the word BRAT:

B - Blame: Article 231 (the War Guilt Clause) forced Germany to accept all the blame for the war.
R - Reparations: Germany had to pay £6.6 billion for the damage caused (a massive amount of money!).
A - Armed Forces: Germany’s army was cut to 100,000 men, they were allowed no tanks or planes, and their navy was restricted.
T - Territory: Germany lost 13% of its land, including the Polish Corridor and its overseas colonies.

Quick Review: How did Germany feel?

Germany called the treaty a Diktat (a dictated peace). They felt it was unfair because they weren't allowed to negotiate. It was like being blamed for a broken window you didn't break alone, and then being forced to pay for the whole house!

Key Takeaway: The Treaty was a compromise that satisfied no one. It left Germany weak and angry, and the Allies divided.


Part Two: The League of Nations and the 1920s

The League of Nations was supposed to be a "world parliament" where countries could talk about their problems instead of fighting. This was called Collective Security.

Successes in the 1920s

The League wasn't a total failure! In the 1920s, it actually helped:

• Aaland Islands (1921): Settled a dispute between Sweden and Finland.
• Upper Silesia (1921): Organized a vote to divide land between Germany and Poland.
• Bulgaria (1925): Stopped Greece from invading Bulgaria.
• Agencies: The League did great work helping refugees and fighting diseases like leprosy.

The Weaknesses of the League

Even though it had good intentions, the League had major "flaws in its armor":

1. The USA didn't join: Even though it was their idea! This meant the League lacked money and power.
2. No Army: If a country ignored the League, it had no way to force them to stop.
3. Slow Decision Making: Everyone had to agree (unanimity), which took forever.

The Turning Point: The Great Depression

In 1929, the world economy crashed. Think of it like a global power cut. When people lost their jobs and money, they started voting for extremist leaders like Hitler. Countries became selfish and stopped cooperating with the League.

Two Big Failures in the 1930s

1. Manchuria (1931): Japan invaded part of China. The League sent a report but did nothing else. Japan simply left the League. It showed the League was toothless.
2. Abyssinia (1935): Mussolini (Italy) invaded Abyssinia (Ethiopia). Britain and France tried to make a secret deal (the Hoare-Laval Pact) to give Mussolini the land. This ruined the League's reputation.

Key Takeaway: By 1936, the League was seen as a failure. It couldn't stop powerful countries from being bullies.


Part Three: The Road to the Second World War

While the League was falling apart, Adolf Hitler was busy breaking the rules of the Treaty of Versailles.

Hitler's Aims

Hitler had three main goals: Abolish the Treaty of Versailles, expand German territory (Lebensraum or "living space"), and unite all German-speakers.

Step-by-Step Escalation

• Rearmament: Hitler started building up the army and brought back conscription (forced military service).
• The Saar (1935): This coal-rich area voted to rejoin Germany. It was a legal victory for Hitler.
• Rhineland (1936): Hitler moved troops into the Rhineland (a "no-go" zone for the German army). The League was too busy with Abyssinia to stop him.
• Anschluss (1938): Hitler united Germany and Austria. This was banned by the Treaty, but Britain and France did nothing.

Appeasement: "The Bully Analogy"

Britain (under leader Neville Chamberlain) followed a policy called Appeasement.
Analogy: Imagine a bully demands your chocolate bar. You give it to him, hoping he will leave you alone. But then he demands your sandwich. Appeasement is giving the bully what he wants to avoid a fight.

The Munich Agreement and Sudetenland

Hitler demanded the Sudetenland (part of Czechoslovakia). At the Munich Conference, Britain and France agreed to let him have it if he promised not to take anything else. Chamberlain returned home claiming "Peace for our time." Spoiler alert: It didn't last.

The Outbreak of War (1939)

Two final shocks led to war:

1. Nazi-Soviet Pact: Hitler and Stalin (enemies!) signed a secret deal to not fight each other and to split Poland between them. This shocked the world.
2. Invasion of Poland: On September 1, 1939, Hitler invaded Poland. Britain and France had promised to protect Poland, so they finally declared war.

Key Takeaway: War broke out because Hitler's aggression finally went too far, and the policy of Appeasement failed to stop him.


Quick Review Box

Wait! Make sure you know these:
• Diktat: The German word for the "forced" Treaty of Versailles.
• Article 231: The "War Guilt" clause.
• Collective Security: The idea that League members would protect each other.
• Appeasement: Giving in to a bully to keep the peace.
• Nazi-Soviet Pact: The 1939 agreement that allowed Hitler to invade Poland without fear of Russia.

Don't worry if this seems like a lot of dates! Focus on the "Why"—why did people make these choices? If you understand the motives, the dates will follow. Good luck with your revision!
