Key topic 2 · The impact of Depression and war, 1928–45

What a Grade 9 answer knows here. Learie Constantine won his case in 1944 because the hotel had breached a contract, not because refusing him was unlawful — there was no law against racial discrimination in Britain until 1965. The remedy reveals the gap.

The 3 lessons

Class and disability in Depression: eugenics and Jarrow

Why is the most famous protest of the 1930s remembered as a triumph when it achieved nothing? The Depression's effects in Britain were regionally concentrated.

Examined through continuity and consequence. Learn class and disability in Depression: eugenics and Jarrow →

Immigration, ethnic tension and the BUF

How does stopping a march in one street produce an Act of Parliament? The interwar minority population was small and concentrated.

The Second World War: national service, aliens, the colour bar and Constantine

What does it tell you that a man had to sue for breach of contract because refusing him a room was legal? Conscription of men began in 1939 and was extended progressively.

The dates that earn marks in this key topic

Two from each lesson, in the order the topic is taught — each with the reason it is worth a mark, and the lesson that places it.

1931 — The household means test is introduced for those whose insurance benefit has expired.: It assessed a family's whole income, which broke up households and produced lasting resentment. (Class and disability in Depression: eugenics and Jarrow)
1934 — Palmers shipyard closes; the Brock Committee recommends voluntary sterilisation and Parliament does not legislate.: One event created Jarrow's unemployment and the other shows eugenic argument being made officially and refused. (Class and disability in Depression: eugenics and Jarrow)
1932 — Mosley founds the British Union of Fascists.: It establishes an organised movement whose later antisemitic turn produced the East End confrontations. (Immigration, ethnic tension and the BUF)
June 1934 — Violence at the BUF's Olympia rally costs it much respectable support.: It shows the movement's methods damaging it before any legislation was passed. (Immigration, ethnic tension and the BUF)
1940 — About 27,000 enemy aliens are interned, including refugees from Nazism; most are released within a year.: It shows how quickly rights can be suspended, and the release shows the policy being recognised as indiscriminate. (The Second World War: national service, aliens, the colour bar and Constantine)
December 1941 — Britain becomes the first country to conscript women.: Compulsory mobilisation made arguments about what women could not do much harder to sustain afterwards. (The Second World War: national service, aliens, the colour bar and Constantine)

The people to place

Ellen Wilkinson — Member of Parliament for Jarrow who accompanied the march and wrote its account. (Class and disability in Depression: eugenics and Jarrow)
Laurence Brock — Chaired the 1934 committee that recommended voluntary sterilisation, which Parliament did not enact. (Class and disability in Depression: eugenics and Jarrow)
Oswald Mosley — Founder and leader of the British Union of Fascists; interned in 1940. (Immigration, ethnic tension and the BUF)
John Simon — Home Secretary who declined to ban the October 1936 march and introduced the Public Order Bill afterwards. (Immigration, ethnic tension and the BUF)
Learie Constantine — Cricketer and Ministry of Labour welfare officer who sued the Imperial Hotel successfully in 1944. (The Second World War: national service, aliens, the colour bar and Constantine)
Ernest Bevin — Minister of Labour and National Service who directed the wartime mobilisation of labour, including the conscription of women. (The Second World War: national service, aliens, the colour bar and Constantine)

What students say — and what is actually the case

“The Jarrow Crusade succeeded in getting help for the town.” — The petition was received, the Prime Minister declined to meet the marchers, and their benefit was reduced for the period they had been away. Jarrow's position improved with rearmament, not with the march. (Class and disability in Depression: eugenics and Jarrow)
“Cable Street defeated British fascism.” — The BUF continued and Mosley was interned in 1940 under wartime powers. What the day did was make a permitted march impossible, which produced the Public Order Act. (Immigration, ethnic tension and the BUF)
“Constantine's case made racial discrimination illegal.” — He won on the innkeeper's duty and breach of contract. Racial discrimination remained lawful in Britain until the Race Relations Act of 1965. (The Second World War: national service, aliens, the colour bar and Constantine)
