Final answer:
The purpose of Adolf Hitler's Lebensraum policy was to expand German territory in Eastern Europe to provide 'living space' for the German population, according to Nazi ideology.
Step-by-step explanation:
The purpose of German leader Adolf Hitler's Lebensraum policy was to expand German territory. This concept sought additional 'living space' for the German population by annexing territories, primarily in Eastern Europe. Lebensraum was a key component of Nazi ideology, driven by the belief in the superiority of the Aryan race and the need for territorial expansion to support a growing German nation.
The goal was to resettle German families in these seized lands, thereby displacing the native Slavic populations and securing more space for the alleged 'master race'. Hitler's foreign policy actions, including the annexation of Austria and Czechoslovakia's Sudetenland, were steps towards achieving this objective under the guise of reuniting German-speaking people and creating a Greater Reich.
