IB History: Refugees in Europe and Indochina — notes, maps and essay plans

After 1945 Europe’s borders moved and millions were made to follow them; after 1975 three million people fled Vietnam, Cambodia and Laos. Two maps, one question: what drove people out, and who took them in?

This page gathers the atlas’s IB notes: where each of its 12 chapters fits the syllabus, the concepts and evidence it supports, practice questions with model essay plans, primary sources, and starting points for the Internal Assessment.

Where it fits the course

Every chapter’s IB notes name the parts of the course it serves. Across the atlas they add up to this: It is the paired atlas for the Paper 1 Focused Study Conflict and Displacement, whose page holds a free source-question set.

Chapter by chapter

The atlas holds 72 points of evidence and 40 primary sources across 12 chapters. Chapters 1 and 2 are free, so their evidence is shown here in full; for the others you get one point and the practice question, and the rest waits in the atlas. Each chapter title opens the chapter’s free page, with the full explanation.

  1. By August 1944 about 7.6 million foreign civilians and prisoners of war worked in the Reich, more than a quarter of its labour force, so Germany’s defeat was bound to strand millions of people far from home at once.
  2. Nazi Germany expelled about 920,000 Poles from the western Polish lands it annexed in 1939 and settled more than 300,000 ethnic Germans there by 1941, which shows that moving peoples to fit borders began as Nazi policy.
  3. At Yalta in February 1945 Roosevelt, Churchill and Stalin agreed to move Poland’s eastern border to roughly the Curzon Line and to return each other’s liberated citizens, decisions that turned the end of the war into a second, planned displacement.
  4. Nearly six million displaced persons were repatriated from the western zones of Germany by the end of September 1945, yet more than a million refused or were unable to go home and became the “last million” of the camps.
  5. The Allied category of “displaced person” covered citizens of Allied states and excluded Germans, so the millions of German civilians who fled west in early 1945 received no international aid and became the defeated state’s own problem.
  6. Estimates of Europe’s uprooted in May 1945 range from about seven to eight million DPs on German soil to more than 40 million displaced Europeans, a spread that reflects who did the counting and which categories they used.

  1. Section XIII of the Potsdam agreement of 2 August 1945 stated that the transfer of Germans from Poland, Czechoslovakia and Hungary “will have to be undertaken”, asking only that it be “orderly and humane”, which gave the expulsions great-power consent.
  2. On 20 November 1945 the Allied Control Council fixed a plan to move 6.65 million Germans, including 3.5 million from Poland and 2.5 million from Czechoslovakia, turning expulsion into an administrative programme of trains and quotas.
  3. The “wild expulsions” of May to August 1945 drove some 700,000 to 800,000 Germans out of Czechoslovakia before Potsdam, including about 20,000 residents of Brno marched toward Austria, showing that national authorities acted before the Allies decided.
  4. Winston Churchill told the House of Commons on 15 December 1944 that expulsion was the most “satisfactory and lasting” method and that “a clean sweep will be made”, evidence that Britain accepted mass transfer long before the war ended.
  5. The West German census of 1950 counted 7.9 million expellees, 16.5 percent of the population, while East Germany held about 4.3 million, so the expulsions reshaped both German states.
  6. Estimates of German deaths range from about 500,000 documented cases (Overmans, Haar) to 2.2 million in the 1958 West German calculation, and the Czech–German historians’ commission put deaths in Czechoslovakia at 15,000 to 30,000.

Practice questions and essay plans

Every chapter ends with a practice question and a model plan: a thesis, three points with evidence and a link back to the question, a counter-argument and a judgement. The plan for chapter 1 is shown in full; for the others, here is the outline, and the rest is in the atlas.

PAPER 2 · UPROOTED · CHAPTER 1

Examine the reasons why the end of the Second World War in Europe led to mass displacement.

THESIS

The end of the war produced mass displacement because three forces met in May 1945: the Nazi labour and population policies that had already moved millions, the collapse of the Eastern Front that set Germans fleeing, and Allied decisions at Yalta that made borders and populations movable. The last of these turned a temporary emergency into a lasting policy of moving people.

THE THREE POINTS
  1. Nazi policy had already uprooted the largest group of people before the war ended.

    EVIDENCEAbout 7.6 million foreign workers and prisoners worked in the Reich in August 1944, and around 920,000 Poles had been expelled from annexed lands.

    LINKDefeat freed these people at once, so the DP problem was a direct legacy of Nazi rule. Herbert’s research shows the system was built into the war economy, not improvised at the end.

  2. The military collapse of 1945 created a second, German exodus that the Allies did not count as refugees.

    EVIDENCEMillions fled East Prussia and Silesia from January 1945, often too late because officials such as Erich Koch had banned evacuation.

    LINKFlight emptied districts before any border decision and set up the expulsions that followed. The distinction between flight and expulsion matters for any count of German losses.

  3. Allied wartime agreements ensured that peace would move even more people.

    EVIDENCEThe Yalta accords of February 1945 moved Poland’s border to the Curzon Line and bound Britain and the United States to repatriate Soviet citizens.

    LINKDisplacement after May 1945 therefore became deliberate policy, which explains its scale. Repatriation and border change were political choices made before the guns fell silent.

COUNTER-ARGUMENT

One could argue that the war alone caused the crisis, since every category of displaced person in May 1945, from forced labourers to fleeing Germans, had been created by the fighting and by Nazi occupation before any peace terms were applied. Germans who fled in January 1945 had no decision of the Allies behind them at all.

JUDGEMENT

The war created the emergency, but the peace decided its scale and duration. Nearly six million DPs went home within months, while border changes and transfers agreed by the victors uprooted far larger numbers for years, so Allied decisions were the decisive reason why displacement outlasted the fighting.

Read the chapter behind this plan: Europe Uprooted.

PAPER 2 · UPROOTED · CHAPTER 3

Compare and contrast the population transfers carried out in Poland and in Finland between 1944 and 1950.

THESIS

Both transfers followed the same cause, the Soviet Union’s annexation of eastern borderlands in 1944–45, and both aimed at ethnically uniform states. They differed sharply in method and outcome: Finland resettled its own citizens by democratic choice and law, while Poland’s communist state combined exchanges, expulsions and internal deportation by force.

THE THREE POINTS
  1. The causes were similar: Soviet territorial gains forced both states to absorb people from lost lands.

  2. The methods differed: Finland relied on choice and compensation, Poland on coercion.

  3. The outcomes differed in who paid the cost.

The evidence for each point, the counter-argument and the judgement are in the IB notes of chapter 3 in the atlas. Read the chapter first: Borders Move, People Follow.

PAPER 3 · UPROOTED · CHAPTER 10

To what extent did the Geneva meeting of July 1979 resolve the Indochinese refugee crisis?

THESIS

The Geneva meeting resolved the immediate crisis of closed shores by restoring the bargain of first asylum for resettlement, but it did not resolve the underlying causes of flight or the Cambodian emergency, and its success depended on Vietnam restricting departures and on Western generosity that later faded.

THE THREE POINTS
  1. Geneva reopened the shores by expanding resettlement.

  2. Much of the fall in arrivals came from controls inside Vietnam.

  3. Geneva left the Cambodian emergency and long-term questions unresolved.

The evidence for each point, the counter-argument and the judgement are in the IB notes of chapter 10 in the atlas. Read the chapter first: Geneva and the US Response.

PAPER 2 · UPROOTED · CHAPTER 4

Evaluate the reasons why repatriation failed to resolve the problem of displaced persons in Europe between 1945 and 1947.

THESIS

Repatriation succeeded for most DPs but failed for the people who mattered most to the post-war order, because border changes put their homes under Soviet rule, because the Holocaust and post-war antisemitism left Jews nowhere to return, and because forced return proved morally and politically unsustainable in the West.

THE THREE POINTS
  1. Soviet annexations made return unacceptable for many eastern Europeans.

  2. Jewish survivors had no home to return to.

  3. Forced repatriation discredited itself.

The evidence for each point, the counter-argument and the judgement are in the IB notes of chapter 4 in the atlas. Read the chapter first: The DP Camps.

TEXT · CHAPTER 1

Agreement relating to prisoners of war and civilians liberated by forces operating under Soviet command and forces operating under United States command

CREATOR
Maj. Gen. John R. Deane (United States) and Lt. Gen. A. A. Gryzlov (Soviet Union)
DATE
11 February 1945
ORIGIN
Bilateral agreement signed at the Crimea (Yalta) Conference; text from C. Bevans, Treaties and Other International Agreements of the United States of America 1776–1949, vol. 3 (US Government Printing Office, 1969)

Context. This agreement, with a parallel British–Soviet one signed the same day, governed how liberated Soviet citizens in western Europe were handed back to Soviet authorities after the war.

The Government of the United States of America on the one hand and the Government of the Union of Soviet Socialist Republics on the other hand, wishing to make arrangements for the care and repatriation of United States citizens freed by forces operating under Soviet command and for Soviet citizens freed by forces operating under United States command, have agreed as follows: Article 1. All Soviet citizens liberated by the forces operating under United States command and all United States citizens liberated by the forces operating under Soviet command will, without delay after their liberation, be separated from enemy prisoners of war and will be maintained separately from them in camps or points of concentration until they have been handed over to the Soviet or United States authorities, as the case may be, at places agreed upon between those authorities. …

TEXT · CHAPTER 1

Report of Earl G. Harrison on displaced persons in Germany and Austria (extract on camp conditions)

CREATOR
Earl G. Harrison, US representative on the Intergovernmental Committee on Refugees
DATE
August 1945
ORIGIN
Typescript report to President Truman, Official File 127, Truman papers; US National Archives (NAID 169048805), p. 12

Context. President Truman sent Harrison, dean of the University of Pennsylvania law school, to inspect displaced persons’ camps in Germany and Austria in July 1945, with particular attention to Jewish survivors.

But speaking more broadly, there is an opportunity here to give some real meaning to the policy agreed upon at Potsdam. … then it is difficult to understand why so many displaced persons, particularly those who have so long been persecuted and whose repatriation or resettlement is likely to be delayed, should be compelled to live in crude, over-crowded camps while the German people, in rural areas, continue undisturbed in their homes. As matters now stand, we appear to be treating the Jews as the Nazis treated them except that we do not exterminate them. They are in concentration camps in large numbers under our military guard instead of S.S. troops. One is led to wonder whether the German people, seeing this, are not supposing that we are following or at least condoning Nazi policy.

PICTURE · CHAPTER 1

Displaced persons at the camp at Wittlich, Germany

CREATOR
US Army photographer
DATE
18 April 1945
ORIGIN
Photograph published in History of the Fifteenth United States Army (1946), p. 118

Context. The original caption states that 48 people shared this room. Wittlich, in the Rhineland, was one of hundreds of assembly centres the Allied armies opened for liberated forced labourers in the spring of 1945.

Picture: Displaced persons crowded into a barracks room full of iron beds at the Wittlich camp in Germany, April 1945.

Internal Assessment starting points

Each starting point is an idea for an investigation: a question, the concept it tests, the kinds of sources you could use and where they are held, and one caution. The investigation must be your own work, and your teacher approves the question.
