Summary
Adolf Hitler was the leader of Nazi Germany and the principal political author of the war of conquest, racial empire, and exterminatory violence that defined the European core of World War II.
Historical role
He matters because his regime fused revisionist geopolitics, mass dictatorship, antisemitic ideology, and militarized expansion into a project that destabilized Europe and escalated into continent-wide destruction and genocide.
Connections
Useful for linking the collapse of the interwar order, the Nazi state, World War II in Europe, and the Holocaust.
