The Second World War - Why did the Second World War begin?

This clear, engaging lesson introduces students to the key causes of the Second World War. Learners explore how the Treaty of Versailles created deep resentment in Germany through harsh reparations, territorial losses and the “war guilt” clause. They then analyse how the Great Depression destabilised global politics and fuelled the rise of extremist dictators across Europe and Asia.

Students investigate Hitler’s expansionist aims, including rearmament, the remilitarisation of the Rhineland and the pursuit of Lebensraum. The lesson concludes with an evaluation of why Appeasement and the League of Nations failed to prevent war, encouraging students to weigh misjudgement, economic weakness and international division.

Throughout the lesson, students engage in peer talk, group discussion, and short in‑lesson tasks that build confidence, deepen understanding and support analytical thinking.
