Aztec vs Inca Empire: Two American Empires on a 3D Globe

The two great empires of the Americas rose at the same time, thousands of kilometres apart, and never met. The Aztecs ruled central Mexico from an island city in a lake. The Incas ruled a long strip of the Andes from Cusco, linked by thousands of kilometres of roads. Both fell to small Spanish forces in the 1500s.

Two ways to run an empire

The Aztec Empire was a Triple Alliance of three cities, led by Tenochtitlan. Conquered cities kept their own rulers but had to send tribute such as food, cloth and feathers. The Inca state was more tightly run from Cusco. It moved whole communities, kept huge storehouses, and asked people to work for the state for part of the year, a system called mit’a.

Why both fell so fast

The Spanish had steel weapons, horses and guns, but numbers were not on their side. Diseases such as smallpox killed huge numbers of people before and during the conquests. Cortés won with tens of thousands of Indigenous allies who wanted to break Aztec rule. Pizarro arrived just after an Inca civil war between two brothers, Atahualpa and Huáscar.

Quick facts

  • Inca roads ran for around 40,000 km, with rope bridges across deep gorges.
  • Machu Picchu was built by the Incas around 1450.
  • Chocolate, tomatoes and maize were grown in Mexico long before the Aztecs.
  • The Incas had no wheeled carts and no written alphabet, yet ran an empire of millions.
