Mackinder's Heartland Theory

Mackinder's Heartland Theory suggests that the central landmass of Eurasia, called the "Heartland," holds the key to global power due to its size, resources, and strategic position. Control over this region, spanning Eastern Europe to Central Asia, could enable dominance over the "World Island" (Eurasia and Africa), and potentially the entire world. Mackinder believed that whoever controlled the Heartland could become the world's most powerful force, highlighting the importance of geographical advantage in geopolitics and military strategy.
