Definition
The Inca Empire was the largest empire in the pre-Columbian Americas, spanning the Andes Mountains and the Pacific coast of South America in the fifteenth and early sixteenth centuries CE. Its people called it Tawantinsuyu, meaning the four united regions.
Ruled from its capital at Cusco, the empire stretched for thousands of miles through some of the most difficult terrain on earth, binding together dozens of distinct peoples under a single, highly organized administration.
Why it matters
How it works
The Inca state was centralized and tightly managed. Conquered peoples owed labor — building roads, farming state land, serving in the army — rather than taxes in goods or coin. Officials redistributed food and supplies through a network of storehouses, providing a safety net the central government controlled.
This organization gave the empire impressive reach, but its dependence on a single ruler made it vulnerable. A succession war had just weakened the empire when the Spanish arrived, and they were able to topple it with a small force by seizing its leadership and turning internal divisions to their advantage.
