The Inca Empire
The Inca Empire was the largest empire in pre-Columbian America, spanning the Andes Mountains and known for its remarkable road system, architecture, and administrative organization.
Ruling without a system of writing as understood elsewhere in the ancient world, this empire nonetheless organized an extraordinarily vast and mountainous territory through ingenious alternative systems of record-keeping and communication.
Rapid Andean Expansion
The Inca Empire expanded rapidly from its capital at Cusco beginning around 1438, eventually stretching along the Andes Mountains to become the largest empire in the pre-Columbian Americas.
An Extensive Road Network
The Inca built an extraordinary system of roads spanning over 24,000 miles, connecting the far reaches of their mountainous empire and enabling rapid communication through relay runners.
Record-Keeping Without Writing
Lacking a conventional writing system, the Inca recorded information using quipu, an intricate system of knotted cords, to track census data, tribute records, and historical narratives.
Remarkable Stone Architecture
Inca builders achieved extraordinary precision in stone construction, exemplified by sites like Machu Picchu, fitting massive stone blocks together so precisely that no mortar was needed.
Conquest by Spain
The Inca Empire fell rapidly to Spanish conquistador Francisco Pizarro in the 1530s, aided by internal succession conflicts and the devastating impact of European diseases that preceded the conquistadors' arrival.
