Geopolitical Theory examines how geographical factors influence political behavior and international relations. It considers elements like location, resources, and physical terrain, which can shape a nation's power and strategy. This theory helps explain why certain regions are more prone to conflict or cooperation based on their geographic characteristics. Key figures in Geopolitical Theory include Halford Mackinder, who proposed the "Heartland Theory," suggesting that control of central Eurasia could dominate global politics. Another important concept is Nicholas Spykman's "Rimland Theory," which emphasizes the significance of coastal regions in global power dynamics. These theories provide frameworks for understanding global interactions.
