Mackinder, Halford J.

Halford Mackinder was a British geopolitical theorist known for his "Heartland Theory," proposed in the early 20th century. He argued that the most important area for global power lies in the central region of Eurasia, which he called the "Heartland." According to Mackinder, whoever controls this landmass would dominate the world. His ideas influenced military strategy and international relations, particularly during the Cold War. Mackinder’s work highlighted the significance of geography in politics and how access to resources and strategic locations shapes global power dynamics.
