What happened
Spanish prospectors discovered the Potosi silver deposit at Cerro Rico, in modern Bolivia, in 1545. World History Encyclopedia records that at its peak around 1600 the mines numbered over 600 individual operations and yielded some 9 million silver pesos a year, more than every other silver mine on Earth combined at the time, and that by 1600 Spain had transported roughly 25,000 tons of silver from the Americas to Spain, with silver making up more than 85 percent of annual precious-metal shipments back to the Spanish crown by 1540. This flood of bullion coincided with a sustained rise in prices across 16th-century Europe that historians call the price revolution: commodity prices in Spain rose roughly 400 percent over the century. Economic historians have long debated how much of this inflation the American silver actually caused. Earl Hamilton's classic study attributed the price revolution chiefly to the silver influx, but later research points to population growth, credit expansion, and monetary factors that predate the arrival of large American silver shipments as equally important drivers.
Why it matters
The price revolution was Europe's first experience of sustained, continent-wide inflation tied to a specific, traceable monetary cause, and it funded the Spanish Empire's wars and administration for over a century while destabilizing prices and wages everywhere Spanish silver circulated, from Antwerp to the Ottoman Empire, showing for the first time how a single country's mining discoveries could reshape prices across an entire international economy.
How we know
Spanish crown shipping records (the registered treasure fleets) and Seville customs data, first systematically compiled by economic historian Earl Hamilton, document the scale of silver imports, while surviving price records from Spanish and other European markets allow historians to track the resulting inflation directly.
