Since the dawn of time, geography has shaped the fate of nations. This three-part documentary explores how mountains, rivers, seas, and deserts have influenced the decisions of governments, as well as the rise of civilisations. Geography remains a constant force in history, from determining a nation’s location on the world map to its access to natural resources.

While the USA’s ascent as a global power was driven by its unique position between two oceans, Russia’s history has been defined by its relentless search for warm-water ports. China’s geopolitical importance stems from its historical position as the hub of Eurasian trade, from the ancient Silk Road to its current maritime dominance in the Pacific. Today’s global powers owe their status and significance to natural forces. Geography is the ultimate creator of nations.
