The Blitz, Dunkirk and the home front, 1939-1945.

Key ideas

The Second World War reached everyone

Unlike earlier wars, the Second World War struck civilians directly: the Blitz bombed British cities, rationing reshaped daily life, and women entered factories and services in huge numbers. 'Total war' meant the home front was a front line too.

The peace of 1919 sowed future conflict

The Treaty of Versailles punished Germany with the 'war guilt' clause, reparations and lost territory. Many Germans felt humiliated, and economic collapse in the Depression years helped extremists like Hitler win support. Historians debate how directly Versailles caused the Second World War — but few deny it mattered.

Key term — Alliance: An agreement between countries to support each other. Rival alliance systems helped turn a Balkan crisis into a world war.

Common mistakes
  • Blaming the First World War on one country or person The war had multiple interacting causes. Even the assassination only led to war because alliances and war plans turned a local crisis into a continental one.
  • Saying appeasement was simply stupid British leaders feared another war, worried about the economy, and believed Germany had genuine grievances. Judging appeasement requires understanding their constraints, not just hindsight.
