Aztec Tax Collector System

Timeline

1. c. 1325–1350Tenochtitlan · Valley of MexicoIn the early period of the city's founding, Mexica leaders entrusted trusted associates with managing tribute from subject settlements, primarily in kind (maize, cotton cloth, feathers, cocoa beans); tribute was transported by water to the capital's warehouses, laying the practical foundation for the tax collector system.
2. 1365City-states of the Valley of Mexico · Valley of MexicoAfter the Mexica conquered neighboring city-states in the 1360s, calpixqui were stationed in newly subject territories, registering the types and quantities of tribute owed by each town according to tribute lists like those in the Codex Mendoza; tax collectors also supervised corvée labor (misteca) conscription, forming a hierarchical collection network.
3. 1428–1519Provinces of the Aztec Empire · MexicoAt the empire's height, tax collectors were divided into city-state level (calpixque) and imperial central level (huecalpixque), the latter reporting directly to the emperor; tribute was funneled to Tenochtitlan via relay stations and canal networks, supporting the military, temples, and elite consumption, with institutional complexity unmatched in pre-Columbian America.
