Getting Started

Between approximately 1200 and 1450, long before European contact, the Americas were home to a wide array of sophisticated and powerful states. Far from being an undeveloped region, the Americas saw the rise and fall of empires, the flourishing of city-states, and the growth of vast trade networks. This chapter explores the diversity, innovation, and expansion of these state systems, from the large, centralized empires of the Mexica and Inca to the complex regional societies of North America.

What You Should Be Able to Do

  • Explain the key features of different state systems in the Americas.

  • Compare the methods of political and economic organization used by large empires and smaller-scale societies.

  • Analyze how American states expanded their scope and reach over time.

  • Describe examples of continuity and innovation in American state-building.

Key Developments & Analysis

State systems in the Americas developed in diverse ways, reflecting unique cultural and environmental contexts. While some states grew into massive, centralized empires through conquest, others were organized as networks of city-states or large regional chiefdoms built on trade and cultural influence. The following table compares the political and economic structures of these different types of states.

ThemeLarge Imperial States (Mexica, Inca)Decentralized & Regional Polities (Maya, Chaco, Mesa Verde, Cahokia)Why This Difference/Similarity Matters
Political OrganizationHighly centralized, with a single powerful ruler (emperor) and an extensive bureaucracy. The state was built on military conquest and the administration of conquered peoples.Politically fragmented. The Maya city-states, for example, were a collection of independent kingdoms that often competed or allied with one another. Others, like Cahokia, were likely powerful chiefdoms that exerted influence over a region rather than direct control.This shows there was no single model for statecraft in the Americas. Political power could be concentrated in an imperial capital or distributed among various centers, demonstrating significant diversity in governance.
Methods of ExpansionExpansion occurred through organized military conquest. The Mexica (Aztecs) used their powerful army to conquer neighboring peoples and incorporate them into a vast tribute system. The Inca used a combination of conquest and assimilation, moving conquered peoples and building infrastructure to unify their empire.Expansion was often based on trade, cultural influence, and alliances rather than direct conquest. The societies at Chaco and Mesa Verde built extensive road and communication networks that suggest a wide-reaching economic and religious influence, but not necessarily a unified imperial state.The methods of expansion reveal different state priorities. Imperial states focused on extracting resources through force, while regional polities often expanded their influence through commerce and shared cultural practices.
Economic SystemsEconomies were managed by the central state to extract wealth and labor from conquered populations. The Mexica demanded a tribute system, where conquered subjects paid in goods and labor. The Inca state used the mita system, a mandatory public service requirement for all subjects to work on state projects like roads and farms.Economies were often based on regional trade networks. Cahokia, located near major rivers, was a massive commercial hub for the entire Mississippi River valley. The Maya city-states maintained vibrant trade for luxury goods like obsidian and jade.This contrast highlights different relationships between the state and its people. In empires, the economy was a tool of state control, while in decentralized systems, it was often a source of shared prosperity and cultural exchange among distinct groups.

Evidence Bank

  • Maya city-states: A collection of independent, competing kingdoms in Mesoamerica that shared a culture but were not politically unified. They demonstrate a decentralized approach to state-building, contrasting with the later empires of the region.

  • Mexica (Aztecs): A powerful Mesoamerican empire centered at the city of Tenochtitlan. The Mexica state expanded through military conquest and controlled its subjects through a tribute system, which required payments of goods and labor.

  • Inca: A vast, centralized empire in the Andean region of South America. The Inca state maintained control through an extensive bureaucracy, a comprehensive road network, and the mita system of coerced labor.

  • Chaco: A society in present-day New Mexico that built large, planned towns with monumental public architecture. It served as a major ceremonial, administrative, and economic center for a wide region, connected by roads.

  • Mesa Verde: A settlement of the Ancestral Puebloan people in present-day Colorado, known for its impressive cliff dwellings. This society shows a remarkable adaptation of settlement and agriculture to a challenging canyon environment.

  • Cahokia: The largest urban center of the Mississippian culture, located near modern-day St. Louis. It featured enormous earthen mounds and was the hub of a vast regional trade network, demonstrating state-like complexity in North America.

  • Tribute System: A system of payment used by the Mexica to extract wealth from conquered peoples. Conquered states were required to send goods, raw materials, and sometimes people to the imperial capital as a sign of submission.

  • Mita System: A mandatory public service system used by the Inca Empire. Every citizen was required to perform labor for the state for a set period each year, which allowed for the construction of massive public works like roads and temples.

Skill Snapshots

  • Causation: The development of surplus agriculture in the Mississippi River Valley caused the growth of a large, dense urban center at Cahokia. The Mexica’s powerful military caused the rapid expansion of their empire and the creation of a tribute system to manage conquered peoples.

  • Comparison: The Mexica state was organized as a tribute-based empire, while the Maya were organized into competing city-states. The Inca used a state-managed labor system (mita), whereas Cahokia’s influence was based more on its role as a commercial and cultural hub.

  • CCOT: A key continuity in the Americas was the foundation of states on agriculture. A significant change was the consolidation of power from smaller city-states, like those of the Maya, into large, bureaucratic empires like the Inca. Another change was the increasing scale and reach of state-controlled infrastructure, such as the Inca road system.

Common Misconceptions & Clarifications

  1. Misconception: The Americas were sparsely populated and lacked complex societies before 1492.

    • Clarification: The Americas were home to millions of people organized into a wide range of societies, including city-states, regional chiefdoms, and massive empires with large urban centers like the Mexica capital of Tenochtitlan.
  2. Misconception: The Mexica (Aztecs) and Inca were the only significant states in the Americas.

    • Clarification: While the Mexica and Inca were the largest empires at the time of European contact, other complex state systems existed, including the decentralized Maya city-states and the large mound-building societies of North America, such as Cahokia.
  3. Misconception: All American states were centrally-controlled empires.

    • Clarification: State organization was highly diverse. The Inca Empire was extremely centralized, but the Maya were a collection of independent kingdoms, and the influence of Chaco and Cahokia was likely based more on trade and culture than direct political rule.

One-Paragraph Summary

From c. 1200 to c. 1450, state systems in the Americas demonstrated remarkable diversity, innovation, and growth, developing entirely independent of Afro-Eurasian networks. These states ranged from decentralized collections of city-states, like those of the Maya, to powerful regional centers like Cahokia in North America. The period also saw the rise of large, centralized empires, such as the Mexica in Mesoamerica, who used a tribute system to control their subjects, and the Inca in the Andes, who managed their vast territory through a bureaucratic mita labor system. Together, these examples show that state-building in the Americas followed multiple paths, resulting in a complex political landscape of varied and sophisticated societies.
