Which theory states that whoever controlled the European/Asian coastal land would rule Eurasia and, in turn, the destinies of the world?

• A. Heartland theory
• B. Containment theory
• C. Rimland theory
• D. Continental theory

Answer: (C)

This question tests how geographic thinking links the control of specific spaces to global power. The Rimland theory, proposed by Nicholas Spykman, holds that the coastal belt around Eurasia—the rim from Western Europe through the Middle East to South and East Asia—houses the world’s most important population centers, industrial capacity, and sea‑lanes. Whoever dominates these coastal regions can project naval power, secure crucial chokepoints, and build broad alliances, thereby shaping the destinies of the world. This focus on the coastal rim explains why control of European/Asian littoral lands is seen as decisive for global dominance. The Heartland theory emphasizes Eurasia’s interior, not the rim; Containment is a Cold War policy rather than a geographic theory; and a purely continental approach misses the strategic importance of maritime routes and coastal chokepoints.
