Eurasia is the world’s most expansive region. It connects the East to the West, forming a land bridge that borders Europe, the Asia-Pacific, the Middle East and South Asia. Forming the borders of this massive tract of land are the Northern European Plain, the Carpathian Mountains, the Southern Caucasus Mountains, the Tien Shan Mountains and Siberia. At the heart of Eurasia is Russia, a country that throughout history has tried, to varying degrees of success, to extend its influence to Eurasia’s farthest reaches — a strategy meant to insulate it from outside powers. But this strategy necessarily creates conflict throughout Russia’s borderlands, putting Eurasia a near constant state of instability.
