The Mexica and Inca States

The Mexica (Aztec) empire, centered on Tenochtitlan, was not a territorial empire like Rome. Rome sent governors and garrisons to administer provinces directly. The Mexica instead conquered a city, left its existing ruler in place, and demanded regular tribute: maize, cacao, cotton cloth, gold, captives for sacrifice. Tribute collectors visited on a set schedule. As long as goods kept flowing and the city showed submission, Tenochtitlan left daily governance alone. The threat of a punishing return visit by Mexica warriors, not a permanent occupying bureaucracy, kept the system running. This made the empire a patchwork of tribute relationships rather than a uniformly governed territory.

The Inca empire worked on a different principle: labor instead of goods. The state owned little use for money and instead drafted subjects through the mit'a, a rotational labor tax. Communities sent workers for fixed stretches to build and maintain roads, farm terraces, staff storehouses, or serve in the army. In return, the state fed, clothed, and housed them during service and stored surplus food for famine and festivals. This labor, not currency, built the road network, the terraced mountainsides, and the irrigation that fed cities at high altitude. A chinampa, by contrast, shows how the Mexica built food supply locally: mud and lake vegetation piled into a raised plot in shallow Lake Texcoco, staked with willow trees for root systems, producing several crops a year to feed Tenochtitlan.

Both systems answer the same problem differently: how to run an empire without wheeled transport, draft animals, or writing as we'd recognize it. The quipu, a device of knotted colored cords, let Inca administrators record census counts, tribute quotas, and labor obligations numerically without a writing system. Comparing the Mexica and Inca sets up the unit's larger theme: empires organized government, labor, and belief in strikingly different ways before 1450.
