To what extent can Germany be held responsible for causing the two World Wars? Discuss critically.

Assigning guilt for the two World Wars requires separating Germany's undeniable role from the wider systemic failures of each era.

World War I: heavy but shared responsibility

• Germany's Weltpolitik, the naval race with Britain and the "blank cheque" to Austria-Hungary in July 1914 escalated a Balkan crisis, while the Schlieffen Plan's invasion of neutral Belgium turned it into a general war. Fritz Fischer famously argued that Berlin consciously grasped for world power.
• Yet responsibility was collective: rival alliance blocs, imperialist competition, Balkan nationalism after Sarajevo, Austria's ultimatum and Russia's early mobilisation fed an escalatory spiral — Europe, in Lloyd George's phrase, "slithered over the brink". The Versailles war-guilt clause (Article 231) was more a victors' verdict than balanced history.

World War II: primarily German responsibility

• Hitler's programme — rearmament, remilitarising the Rhineland (1936), the Anschluss and Sudetenland annexation (1938), and the invasion of Poland (1939) driven by Lebensraum ideology — was deliberate, planned aggression.
• Others built the enabling conditions: Versailles' punitive terms bred revanchism, the Depression carried Nazism to power, Anglo-French appeasement at Munich (1938) and the League's paralysis over Manchuria and Abyssinia emboldened aggression, and the Nazi-Soviet Pact (1939) sealed Poland's fate.

Germany can therefore be held substantially, but not solely, responsible for the First World War, and overwhelmingly — though within an environment shaped by others' failures — for the Second. The systemic lesson endures: unchecked militarism, humiliating peace settlements and the collapse of collective security are what make world wars possible.
