Definition: Trench Warfare 1914-1918

Life and death on the Western Front, and why the war lasted so long.

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 First World War had long and short causes

Long-term causes — alliances, militarism, imperial rivalry and nationalism — built the tension over decades. The short-term trigger was the assassination of Archduke Franz Ferdinand in Sarajevo in June 1914. GCSE answers must connect the trigger to the deeper causes rather than blaming one event alone.

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.
