This chapter is the starting point for the entire AMSCO U.S. History sequence. It covers the tens of thousands of years of human habitation in the Americas before Europeans arrived, the diversity of Native American societies across the continent, and the major civilisations that developed in Central and South America. If you are coming in cold, this is the right place to begin: everything that follows in the course (European colonisation, the Columbian Exchange, colonial settlement) builds on what was already here. The core question the chapter sets up is: who lived in the Americas, how did they live, and what was the state of the hemisphere when European contact finally happened in the late 1400s?
People first arrived in the Americas up to 40,000 years ago, likely crossing a land bridge from Asia to Alaska. By the 1490s, an estimated 50 to 75 million Native Americans lived across the hemisphere, in societies ranging from small semi-permanent settlements to massive urban civilisations like the Aztecs. Europeans, Asians, and Americans had no knowledge of each other until Columbus's voyages brought the hemispheres into contact.
Native Americans
The original inhabitants of North and South America. In simple terms, this is the umbrella label for all the indigenous peoples living in the Americas before European contact.
Tribes
A group of Native Americans who share the same culture, language, and territory. Think of it as the primary political and social unit for most indigenous peoples, though the size and structure varied enormously.
Nomadic
Moving from place to place, often in search of food or other resources. In simple terms, nomadic peoples did not settle permanently in one location; they followed seasonal food sources like buffalo herds.
Civilisation
A complex society with a high level of organisation, culture, and government. In this chapter, the term specifically refers to the Maya, Aztec, and Inca societies, which had cities, trade networks, and scientific achievements.
Land bridge (Beringia)
The strip of land that once connected Siberia and Alaska, now submerged under the Bering Sea. This is the most widely accepted explanation for how the first humans reached the Americas.
Mound-building cultures
Native American societies (Adena, Hopewell, Mississippian) in the Mississippi and Ohio River valleys that constructed large earthen mounds. Think of these as the most architecturally ambitious cultures in pre-contact eastern North America.
League of the Iroquois
A political confederacy formed by Iroquois tribes in the Northeast (present-day New York). In simple terms, it was an alliance that allowed multiple tribes to coordinate defence and governance across a wide region.
Colonisation
The process of establishing and maintaining control over a territory or region by a foreign power. This term sets up the entire rest of the course.
Exploration
The act of travelling to and examining new or unknown places. In this context, it refers to the European voyages of the 15th and 16th centuries that brought the hemispheres into contact.
Cahokia
A major Mississippian settlement near present-day East St. Louis, Illinois, with as many as 30,000 inhabitants. Think of it as the largest pre-contact city in North America.
Archaeologists estimate the first people arrived in North America as much as 40,000 years ago
They likely crossed a land bridge (Beringia) connecting Siberia and Alaska, now submerged under the Bering Sea
Over thousands of years, successive generations migrated southward from the Arctic Circle to the southern tip of South America
By the 1490s, Native populations across the entire hemisphere are estimated at 50 to 75 million people
Most North American Native Americans lived in semi-permanent settlements with populations seldom exceeding 300
Gender roles were common: men made tools and hunted, women grew crops (corn, beans, tobacco)
Societies varied widely in complexity and lifestyle:
Great Plains (Sioux, Pawnee): nomadic peoples who followed buffalo herds
Southwest (Pueblos): lived in multistoried buildings, developed intricate irrigation systems for farming
Eastern Woodlands: prospered near the Mississippi River with a rich, varied food supply
Mound builders (Adena, Hopewell, Mississippian): evolved in the Mississippi and Ohio River valleys; built permanent settlements supported by hunting, fishing, and agriculture
Cahokia: the largest Mississippian settlement, with up to 30,000 inhabitants, near present-day East St. Louis
Northeast (Iroquois): formed the League of the Iroquois, a political confederacy that held off rival Native Americans and Europeans through the 17th and 18th centuries
Mississippian culture began to decline in the 15th century for reasons that remain unknown
The majority of Native Americans in the 1490s (estimates up to 25 million) lived in Central and South America
Three major civilisations emerged in this region:
Maya (c. A.D. 300–800): built cities in the rain forests of the Yucatan Peninsula (present-day Guatemala, Belize, southern Mexico)
Aztecs: ruled a vast empire from central Mexico; their capital, Tenochtitlan, rivalled Europe's largest cities in size and population
Incas: ruled a vast empire in Peru
All three civilisations developed highly organised societies, extensive trade networks, and calendars based on accurate scientific observations
Until the late 1400s, Americans, Europeans, and Asians had no knowledge of each other's continents
Viking voyages and settlements around the year 1000 (Greenland, North America) had no lasting impact
Columbus's voyages of exploration finally brought Europe and the Americas into sustained contact
The land bridge migration theory is still actively debated by archaeologists and geneticists. Modern DNA evidence from indigenous populations on both continents broadly supports the Siberian migration route, though the timing and number of migration waves are still being refined. This is a good example of how historical narratives are updated as scientific tools improve.
The Iroquois Confederacy is sometimes cited as an influence on the framers of the U.S. Constitution, particularly its model of representative governance among distinct political units. Whether the influence was direct or indirect is debated, but the connection is raised frequently in AP exam contexts.
Students often assume Native Americans were a single, uniform group. They were not. Hundreds of distinct tribes, languages, and cultures existed, from nomadic plains societies to city-states with tens of thousands of inhabitants.
Students sometimes think "civilisation" in this context means only European-style cities. The Maya, Aztec, and Inca civilisations had urban centres, trade networks, and scientific achievements that matched or exceeded contemporary European equivalents.
It is a common error to treat pre-contact North America as empty or sparsely populated. Population estimates for the 1490s range from 50 to 75 million across the hemisphere, with major settlements like Cahokia reaching 30,000 people.
Students sometimes confuse the Maya, Aztec, and Inca civilisations or place them in the wrong regions. Maya: Yucatan/Central America. Aztecs: central Mexico. Incas: Peru.
⚠️ The AP exam frequently tests the diversity of Native American societies. Be prepared to compare different regional groups (Plains nomads vs. Pueblo irrigators vs. Mississippian mound builders vs. Iroquois confederacy).
⚠️ Know the three major Central/South American civilisations and what distinguished each: Maya (cities in rain forests, A.D. 300–800), Aztecs (Tenochtitlan, central Mexico), Incas (Peru).
⚠️ The land bridge theory and the estimated population of the Americas in the 1490s are commonly tested factual points.
⚠️ Understand the concept of hemispheric isolation: neither side knew the other existed until the late 1400s.
True or false: The first people to arrive in the Americas came from Europe.
A: False. They migrated from Asia across a land bridge connecting Siberia and Alaska.
Fill in the blank: The estimated Native population in the Americas in the 1490s ranged from ______ to ______ million.
A: 50 to 75 million.
True or false: The League of the Iroquois was a military alliance in the Great Plains.
A: False. It was a political confederacy of Iroquois tribes in the Northeast (present-day New York).
Fill in the blank: The largest Mississippian settlement, ______, had as many as 30,000 inhabitants.
A: Cahokia.
True or false: Viking settlements in North America around the year 1000 had a lasting impact on the continent.
A: False. They had no lasting impact.
Q: How did the first people arrive in the Americas, and approximately when?
A: They crossed a land bridge (Beringia) connecting Siberia and Alaska, possibly as early as 40,000 years ago. They then migrated southward over thousands of years.
Q: Describe two examples of complex Native American societies in North America before European contact.
A: The Pueblos in the Southwest built multistoried buildings and developed intricate irrigation systems. The Mississippian culture in the river valleys built permanent settlements, including Cahokia with up to 30,000 inhabitants.
Q: What were the three major civilisations of Central and South America, and where was each located?
A: The Maya in the Yucatan Peninsula (Guatemala, Belize, southern Mexico), the Aztecs in central Mexico, and the Incas in Peru.
Q: What did the Maya, Aztec, and Inca civilisations have in common?
A: All three developed highly organised societies, carried on extensive trade, and created calendars based on accurate scientific observations.
Q: Why did Europeans and Americans have no contact before the late 1400s?
A: Neither side knew the other's continent existed. Viking voyages around the year 1000 reached North America but left no lasting impact. It was Columbus's voyages that finally brought the hemispheres into sustained contact.
This material connects directly to AMSCO Chapter 2 and APUSH Period 1, where European exploration and the Columbian Exchange transform the hemisphere. Understanding what Native American societies looked like before contact is essential for analysing the impact of colonisation.
The Iroquois Confederacy reappears later in discussions of colonial-era alliances and the political ideas that influenced the U.S. Constitution. The diversity of indigenous societies is also a recurring theme in exam questions about cultural interaction and conflict.
