The Fall of the Inca Empire

1533 CE — Andes, Inca Empire / Spain

Today: Peru (Cajamarca and Cusco)

Francisco Pizarro reached Peru with fewer than 200 men and captured the largest empire in the Americas within a year. He arrived at the perfect moment: smallpox, spreading overland ahead of any European, had already killed the Inca emperor and his heir, plunging the empire into a civil war between two brothers. Pizarro seized the exhausted victor at their first meeting. Again the decisive weapons were disease and a succession crisis — an empire that fell not because it was weak, but because it was caught mid-collapse.

Worth knowing: The captured Inca emperor offered to fill a room with gold for his ransom — and did, from across the empire. The Spanish took the gold, melted it into bars, and executed him anyway.

Pattern: Demographic shock & recovery — A sudden collapse in population (plague, famine, mass violence) creates labor scarcity that reorders economy and society.
