The Post-War Conferences

---

Overview

Subject: History
Level: GCSE (Key Stage 4) – Year 10/11
Curriculum Area: AQA GCSE History (Germany, 1890–1945: Democracy and Dictatorship OR Conflict and Tension Between East and West, 1945–1972)
Topic: The Tehran, Yalta, and Potsdam Conferences: their impact on the Cold War

This lesson focuses on the three major wartime conferences: Tehran (1943), Yalta (February 1945), and Potsdam (July-August 1945). It will analyse and compare their key decisions and discuss how they contributed to tensions that led to the Cold War. The lesson avoids group activities and will hone students’ ability to think critically about whether these conferences marked collaboration, conflict, or a mixture of both.

---

Lesson Objectives

By the end of the lesson, students will be able to:

1. Identify the key decisions made at Tehran, Yalta, and Potsdam.
2. Analyse how these decisions set the groundwork for Cold War tensions.
3. Compare and contrast the conferences, evaluating common threads and points of divergence.
4. Support a coherent argument about the conferences' role in the origins of the Cold War.

Materials Needed

• Whiteboard/Interactive board
• Printed handouts for clarity on key information and timelines
• Visual stimuli: map showing agreed zones of Germany, iconic photographs from the conferences, and an excerpt from Winston Churchill's “Iron Curtain” speech (for context)
• A3 paper and markers for a plenary timeline task

Lesson Plan Details

Starter (0-5 mins): Memory Check Prompt

Write on the board:

• “What do you already know about the Cold War? Who were the major nations involved, and how did their relationships change after WWII?”

Students take 2 minutes to note their initial ideas (in silence). Each student shares 1 point, and teacher annotates the board, linking answers to themes of trust and tension.

Purpose: Begin framing the idea of alliances shifting from unity in WWII to division in the Cold War.

Mini-Lecture Part 1 (5-15 mins): Tehran and Yalta

1. Introduce Tehran (1943):

   • Primary Attendees: Roosevelt (USA), Churchill (UK), Stalin (USSR).
   • Key Agreements: Opening of a second front in Western Europe, divisions of Europe post-war (idea of zones of influence).
   • Highlight early optimism and cooperation but looming tensions (e.g., Churchill sceptical about Stalin).

2. Transition to Yalta (Feb 1945):

   • Discuss WWII nearing its end and Allied victory imminent.
   • Primary Decisions: Division of Germany into four zones; free elections in Eastern Europe; United Nations creation.
   • Subtle tension: Describe how Stalin’s plans for Eastern Europe began to worry Churchill and Roosevelt.

Use visual aids: Show a map displaying post-WWII zonal agreements in Germany.

---

Mini-Lecture Part 2 (15-25 mins): Potsdam (July–Aug 1945)

1. Context: WWII victory realised; Roosevelt replaced by Truman (harsher stance on USSR); Churchill replaced mid-conference by Attlee.
2. Major Developments:
   • Agreed: Finalisation of the German zones and details of war reparations (struggled over amounts USSR demanded).
   • Disputes: Stalin’s growing control over Eastern Europe, refusal for free elections in Poland, and Truman’s revelation of the atomic bomb.
   • High Tensions: Breakdown of trust and growing ideological divisions between the capitalist West and communist East.

Illustrations: Show archival images of the three conferences to visually track the changing tone.

Ask students: “How do you think Germany’s future was influencing these tensions?” Take 2-3 short answers to guide analysis.

---

Analysis Task (25-35 mins): Comparison Table

Distribute handouts with blank comparison tables titled: “Tehran, Yalta, and Potsdam: Key Agreements and Sources of Tension”.

Instructions:

• Column 1: Summarise key agreements at each conference.
• Column 2: Identify tensions or disagreements.
• Column 3: Predict how these tensions might fuel the Cold War.

Students complete the table individually. While they work, teacher checks progress, offering brief clarification where needed.

---

Plenary (35-45 mins): Cause-Effect Timeline Activity

Ask: “Were the conferences more about collaboration or conflict? Let’s build a timeline to help us decide.”

Steps:

1. Draw a blank timeline on the whiteboard (1943–1945). Divide it into three sections for Tehran, Yalta, and Potsdam.
2. Teacher guides students to place key decisions and tensions in appropriate places on the timeline (use A3 paper if they prefer to do this on their desks first). For example:
   • Tehran = Collaboration (agreed second front, zones of influence).
   • Yalta = Mixed (agreement over Germany, but concerns over Stalin’s intentions).
   • Potsdam = Conflict (disputes over reparations and Eastern Europe).

Final Question:

• Was the Cold War inevitable by the end of Potsdam? Each student delivers a short 1-2 sentence verbal response based on what they’ve learned.

---

Extension/Homework

Write a brief GCSE-style exam response:

“To what extent were the conferences of Tehran, Yalta, and Potsdam responsible for the outbreak of the Cold War?” (12 marks)

• Include 3 key points (one for each conference).
• Explain how agreements or tensions contributed to mistrust and ideological conflict.

Notes for Teachers

• This lesson aligns with AQA’s Conflict and Tension specifications. Adjust for other boards by tailoring the focus (e.g., Stalin’s behaviour in Eastern Europe for OCR or Edexcel).
• It avoids group-based tasks to meet the teacher’s preference but still uses interactive elements like visuals, timelines, and prompts.
• This format emphasises structured thinking to improve critical analysis skills required for GCSE assessments.
