How did Adolf Hitler’s idea of Lebensraum shape German foreign policy?

Adolf Hitler’s concept of Lebensraum (living space) was the central pillar of Nazi Germany’s foreign policy, driving the regime toward aggressive territorial expansion in Eastern Europe. Hitler believed that Germany required vast new territories to secure food, raw materials, and land for colonization, which he argued were essential for the survival and dominance of the "Aryan race".12

This ideology shaped foreign policy in several critical ways:

• Targeting the East: Hitler explicitly sought to conquer lands in the Soviet Union, specifically coveting the agricultural wealth of Ukraine and resources in the Urals and Siberia.12
• Racial Justification: He framed this expansion as a moral right, viewing Slavic and Jewish populations as Untermenschen (subhumans) who should be displaced, enslaved, or exterminated to make room for German settlers.12
• Strategic Rearmament: To achieve these goals, Hitler prioritized rapid military buildup, repudiating the Treaty of Versailles and preparing the economy for war.2
• Diplomatic Maneuvering: Hitler used deceptive diplomacy, such as the German-Soviet Nonaggression Pact, to secure his flanks before launching Operation Barbarossa in 1941 to seize his desired Lebensraum.12

Ultimately, this pursuit of territorial expansion led to the Holocaust and the catastrophic destruction of World War II.1
