The word "heartland" combines "heart," symbolizing the vital center (from Old English heorte), and "land," denoting territory. It emerged in the early 20th century, influenced by geopolitical theories (e.g., Mackinder’s "Heartland Theory"), to describe a nation’s strategic core. The metaphor reflects the heart’s biological centrality, extended to geography and ideology.
