Rimland Theory

The Rimland Theory, proposed by geopolitician Nicholas Spykman in the 1940s, emphasizes the strategic importance of coastal regions, or "rimlands," surrounding Eurasia. Spykman argued that these areas, which include parts of Europe, the Middle East, and Asia, are crucial for controlling global power dynamics. He believed that whoever dominates the rimlands can influence the heartland of Eurasia and, by extension, global politics and security. Essentially, the theory highlights how coastal and border areas can be more significant than inner territories in determining a nation's strength and stability in international relations.
