Background to Modern Migration (Edexcel GCSE History) : Revision Note
Why did migration to Britain change after 1900?- Timeline & Summary
IMAGE
Migration to Britain changed significantly in the 20th and 21st centuries. After the World Wars, Britain needed workers to help rebuild the country. People from across the Commonwealth, like the Caribbean, India, and Pakistan, were encouraged to move. Migrants also came to escape war or persecution, such as Jewish refugees in the 1930s and Ugandan Asians in the 1970s. Over time, migrants came from more countries than ever before, including parts of Africa, Eastern Europe, and the Middle East.
The government began to control migration more through immigration laws, especially from the 1960s onwards. These laws made it harder for people from the Commonwealth and other non-European countries to settle in Britain. At the same time, Britain's role in the world changed. The British Empire ended, and new links were formed through the Commonwealth and the European Union. These changes all helped shape who could come to Britain, why they came, and where they settled.
Examiner Tips and Tricks
As the name of the topic is Migrants in Britain, c.800-present, there is no end time limit. Use your own knowledge and experiences of migration today in an exam question. The war in Ukraine is a fantastic piece of evidence in a modern migration exam answer about the patterns, experiences and impact of migration.
Changes in Modern British society
The impact of the First and Second World Wars
Britain fought in two world wars
First World War, 1914-1918
Second World War, 1939-1945
In both wars, Britain relied on its empire to provide troops and labourers

Lascars played a vital role transporting food, weapons, and troops across dangerous waters
Migrants and their descendants helped run transport, factories, and hospitals in wartime Britain
Britain had been heavily bombed in the Second World War
German attacked destroyed ports, roads and railway networks
Britain needed workers to rebuild the country
The wars had caused major labour shortages in Britain

End of the British Empire
After 1945, the British Empire began to collapse because:
Britain was in debt after the Second World War
It did not have the money needed to maintain an empire
After the war, global powers like the USA and new organisations like the United Nations supported self-determination
This was the right of people to rule themselves
Many countries in Asia, Africa and the Caribbean began to demand independence
India was the first colony to become independent in 1947
By the 1960s, most of Britain's empire had collapsed
Creation of the Commonwealth and the European Union
The Commonwealth
In 1931, Britain created the Commonwealth of Nations
All members were former colony of the British Empire
Commonwealth countries:
Traded with Britain
Shared language and education systems
Some countries had dual nationality rights with Britain
Examiner Tips and Tricks
A common mistake in exam answers is treating the Commonwealth as if it was just the same as the British Empire.
People were forced to be a colony of the British Empire; membership to the Commonwealth was voluntary.
If you’re talking about post-1945 migration, make sure you're referring to Commonwealth migration, not 'imperial' or 'colonial migration'.
The European Union
In 1973, Britain became one of the nine members of the European Economic Community (EEC)
This later became the European Union (EU)
Member countries could:
Trade freely with each other without tariffs
Move freely so citizens could live, work, and study in any other EU country
In 2016, Britain voted to leave the European Union
Controlling migration
A common theme throughout the 20th century is some native English people believing that there were too many migrants living in Britain
In the 1970s, anti-immigration groups such as the National Front appeared in Britain
The government responded by passing laws to restrict who could and could not enter the country
Immigration laws
Aliens Act (1905)
Aimed at restricting Eastern European Jewish migrants
People could only migrate to Britain if they had money or a job
British Nationality Act (1948)
Gave Commonwealth citizens the right to settle in Britain
Commonwealth Immigrants Act (1962)
Only migrants with valuable skills in professions with labour shortages could live in Britain
Eligible migrants were given a voucher
Commonwealth Immigrants Act (1968)
A reduction in the number of jobs that made migrants eligible for vouchers
Could only migrate if they had grandparents or parents born in Britain
Immigration Act (1971)
Voucher system replaced with work permits only valid for a specified period of time
This rule did not apply to those with British parents or grandparents
Nationality Act (1981)
Non-British citizens no longer had the right to stay in Britain
Examiner Tips and Tricks
Students often struggle to remember each immigration law in this section. To help you to remember, you could use the mnemonic "All British Citizens Come In Numbers":
Aliens Act – 1905
British Nationality Act – 1948
Commonwealth Immigrants Act – 1962
Commonwealth Immigrants Act –1968
Immigration Act – 1971
Nationality Act – 1981
Change & continuity in Modern migration & patterns of settlements
Change
The Commonwealth
Many migrants came from the Commonwealth
They were escaping war and persecution
They wanted a better quality of life
India and Pakistan (1947)
The partition of India and Pakistan caused war
Kenya (1967)
After independence, President Jomo Kenyatta made all citizens decide whether they wanted to be British or Kenyan
By 1968, 20,000 Kenyans migrated to Britain and settled mainly in London or Leicester
Uganda (1972)
President Idi Amin ordered the removal of all Asians from Uganda, despite their input to the economy
After failed negotiations, the British government offered either British or Indian citizenship to all Asian Ugandans
27,000 moved to Britain, many settling in Leicester
Asylum seekers
In 1951, Britain agreed to the United Nations Convention on Refugees
Britain agreed to offer asylum for people facing war and persecution
In recent decades, many asylum seekers have come to Britain from:
Syria
Afghanistan
Ukraine
Many migrants come to Britain legally through asylum
Once they have been granted asylum they are referred to as refugees
There are a growing number of migrants who, out of desperation, come to Britain illegally by:
Paying smugglers to transport them in unsafe boats across the English Channel
Hiding in delivery vehicles, such as lorries, without the driver's knowledge
Examiner Tips and Tricks
There is a key differences between asylum seekers and refugees.
An asylum seeker is asking for safety.
A refugee has received it.
For example, a person fleeing war in Syria might arrive in Britain and apply for asylum. At this stage, they are an asylum seeker.
If the UK government agrees they are at risk and gives them protection, the person has now become a refugee.
The European Union
After 2004, nine Eastern European nations joined the EU
Migration from Poland, Bulgaria and Romania to Britain increased dramatically
Many EU migrants could find better paid jobs in Britain than what was available to them in their origin country
Continuity
Similar to the Early Modern period, the government invited migrants from certain countries to settle in Britain
The Windrush Generation
The government encouraged Caribbean migrants to help rebuild Britain after the Second World War
They filled labour shortages in:
The NHS
The London Transport System
Migrants commonly drove buses and trains
The name 'Windrush' comes from the third, and most well-known, boat to bring Caribbean migrants to Britain
This arrived in Tilbury in June 1948
From 1948 to 1955, over 18,000 migrants had moved from the Caribbean to Britain

European migration
Like in Medieval times, migrants continued to come from Europe
The First World War caused 250,000 Belgians to migrate to Britain
Most migrants returned to Belgium in 1919

The Second World War triggered 160,000 Polish migrants to travel to Britain
Many Polish migrants stayed in Britain
Their country had become a communist satellite state of the USSR after the war
Polish communities thrived, especially in Bradford, Yorkshire
After Ireland became independent from Britain in 1922, Irish migrants continued to migrate to Britain
Irish migrants were exempt from the 1905 Aliens Act
Most joined existing Irish communities across Britain
Jewish migration
Jewish migration continued into the 20th century
After 'Kristallnacht', many Jewish people no longer felt safe in Nazi-occupied territories
Between December 1938 and September 1939, around 10,000 Jewish children arrived in Britain from:
Germany
Austria
Czechoslovakia
Poland
The evacuation of Jewish children to Britain was called Kindertransport (Children’s Transport)
Many of the children remained in Britain permanently
The Holocaust killed many of their relatives
Their homes had been destroyed or taken during or after the Second World War

Partial answer:
One reason migration to Britain changed was because of the impact of the Second World War. During the war, Britain relied heavily on support from people across the British Empire, including over 8 million soldiers and workers from places like India, Africa, and the Caribbean. After the war, Britain faced serious labour shortages and needed workers to rebuild its economy. As a result, people from former colonies were encouraged to migrate, especially to work in the NHS, London Transport, and factory jobs. This was a major change because, for the first time, large numbers of non-European migrants were actively recruited and settled in Britain, This made Britain more diverse than in any previous period.
Examiner Tips and Tricks
Focus on the word “why.” This question is not just asking what changed, but why those changes happened. Always link back to causes such as:
The creation of the Commonwealth.
Britain joining the European Union.
An increase in asylum seekers.
The passing of immigration laws.
