The Rimland Theory, proposed by Nicholas Spykman in the 1940s, emphasizes the geopolitical significance of the coastal fringes of Eurasia, which he referred to as the 'rimland.' According to this theory, control over the rimland is essential for global power, as it serves as a buffer zone between land-based powers and sea powers. This theory connects to various geographical factors influencing global issues by highlighting how strategic locations can impact political dynamics and security concerns across regions.
