Karl Haushofer

Karl Haushofer (1869–1946) was a German geographer and a prominent advocate of geopolitical ideas in the early 20th century. He is best known for his association with the concept of Lebensraum and his influence on Nazi ideology, which used his ideas to justify territorial expansion. Haushofer's work emphasized the importance of geography in shaping national power and was characterized by a deterministic view of state behavior.
