Sep 9, 2025

Overview

This lecture reviews state-building in the Americas from 1200 to 1450, focusing on political structures, continuity, and innovations among Maya, Aztec, Inca, Mississippian, Chaco, and Mesa Verde societies.

Mesoamerican Civilizations

  • The Maya civilization (250–900 CE) featured decentralized city-states focused on tributary relationships, not territory.
  • Maya states collected tribute (goods, not direct control) and practiced human sacrifice for religious reasons.
  • Aztec Empire (Mashika people, 1345–1528) arose via military strength and strategic alliances.
  • Aztec governance was decentralized, relying on tributary states similar to the Maya model.
  • Conquered peoples paid tribute in goods like food and building materials; human sacrifice was central for religious legitimacy.
  • Aztecs claimed heritage from prestigious previous Mesoamerican civilizations to establish legitimacy.
  • Tenochtitlan, their capital, had 150,000–200,000 people, large marketplaces, palaces, and pyramid temples.

Andean Civilizations

  • Wari civilization preceded the Inca and influenced their structures.
  • The Inca Empire (mid-1400s onward) expanded quickly via military power.
  • Inca state-building was highly centralized with a large bureaucracy ensuring the ruler’s directives were followed.
  • Conquered peoples owed labor through the Mita system (state projects, mining, military).
  • The Incas expanded infrastructure (roads and bridges) and had religion-centered politics.

North American Civilizations

  • Mississippian culture (8th–9th century CE) developed in the Mississippi River Valley, relied on agriculture, and had a hierarchical society led by powerful chiefs (Great Sun).
  • Known for building large burial and ceremonial mounds, especially in Cahokia, their largest city.
  • Ability to mobilize large labor forces for public works indicated strong political organization.

Southwestern Societies

  • Chaco and Mesa Verde societies thrived in the arid American Southwest after the Mississippians.
  • Developed advanced techniques for water transportation and storage due to dry climate.
  • Chacoans built large stone structures with imported timber; Mesa Verde people constructed cliff dwellings from sandstone.

  • Bureaucracy β€” A system of managing government through specialized departments or officials.
  • Great Sun β€” Title for chiefs in Mississippian culture with supreme political authority.

Action Items / Next Steps

  • Review class notes on major American civilizations (Maya, Aztec, Inca, Mississippian, Chaco, Mesa Verde).
  • Prepare a comparison chart of political structures from each civilization for next class discussion.
