The term "Rimland" refers to the coastal fringes of a continent, particularly in the context of geopolitics. It was popularized by political scientist Nicholas Spykman, who argued that the Rimland is crucial for controlling global power dynamics. This area includes regions surrounding the Eurasian landmass, such as parts of Western Europe, the Middle East, and Southeast Asia. Rimland theory suggests that nations controlling these coastal areas can exert significant influence over the interior landmasses. This concept highlights the strategic importance of maritime access and the ability to project power across oceans, making the Rimland a focal point for military and economic interests throughout history.
