Nazi ideology, primarily associated with the National Socialist German Workers' Party, emphasized extreme nationalism, racial purity, and anti-Semitism. It promoted the belief that the Aryan race was superior and sought to create a homogeneous society by excluding and persecuting those deemed inferior, particularly Jews, Romani people, and others. Central to Nazi ideology was the idea of Lebensraum, or "living space," which justified territorial expansion to provide resources for the growing German population. This belief led to aggressive military campaigns and the establishment of a totalitarian state that suppressed dissent and promoted propaganda to maintain control over the populace.
