Spain's rise from a modest Iberian kingdom to the first empire to span the globe begins with Columbus's 1492 voyage and the Habsburg monarchs who followed him. The film traces how conquistadors like those who toppled the Aztec and Inca empires turned New World silver and gold into the engine of Spanish power, financing armies, navies, and a court that dominated Europe for a century. It then follows the cracks in that Golden Age: wars fought on multiple fronts, English and Dutch piracy picking apart Spanish shipping lanes, and a crown that borrowed against bullion still crossing the Atlantic until the debts caught up with it. Historians walk through the mechanics of conquest and the economic mismanagement that followed, using maps, period art, and archival sources to show how an empire built on extracted wealth became dependent on it. The result is less a tale of inevitable decline than a case study in how quickly imperial fortune can curdle into imperial fragility.
