The Americas Before Contact

Before the Word "America" Existed

In the year 1000 CE, the largest city north of Mexico stood on the eastern bank of the Mississippi River, where East St. Louis, Illinois sits today. It was called Cahokia, and at its peak around 1100 CE, it housed between 10,000 and 20,000 people — making it larger than London at the time.

Its central pyramid, Monks Mound, rose 100 feet and covered more ground than the Great Pyramid of Giza. Cahokia's residents played a ball game, maintained long-distance trade networks stretching from the Gulf Coast to the Great Lakes, and built astronomical alignments — woodhenges — to track the solstices. Then, sometime around 1350 CE, Cahokia was abandoned. We don't know exactly why. Climate change, political collapse, soil exhaustion — historians still debate it.

Here is what we do know: for centuries after Cahokia, European explorers, colonists, and settlers arrived in North America and saw an "empty wilderness." They were wrong. They were looking at a continent that had been shaped — forests managed by controlled burns, soil enriched by centuries of farming, animal populations influenced by selective hunting — by millions of people for thousands of years. The emptiness they saw was mostly the silence of catastrophic depopulation caused by the very diseases they had brought with them.

This unit begins where American history actually begins: not in 1492, but millennia earlier, with the people who were already here.

A Continent of Diversity

North America in 1491 was home to somewhere between 2 million and 18 million people — historians debate the numbers fiercely, because European diseases spread faster than European observers and killed people before anyone counted them. These people spoke hundreds of distinct languages and organized themselves into vastly different social, political, and economic systems.

Grouping them as a single "Native American culture" is like grouping the French, Japanese, and Aztec together as a single "non-European culture." The diversity was that profound.

The Eastern Woodlands were home to farming and hunting peoples who built permanent villages, maintained complex political alliances, and managed the forests around them through controlled burning to create better hunting grounds. The Haudenosaunee (Iroquois) Confederacy in present-day New York united five nations — later six — under a constitution that governed war, diplomacy, and internal disputes.

The Great Plains were bison country before the horse, and bison country with the horse after the Spanish reintroduced them in the 1500s. Peoples like the Lakota, Comanche, and Cheyenne built mobile civilizations around the massive bison herds, developing a rich material culture, elaborate spiritual practices, and formidable military traditions.

The Southwest was the domain of the Pueblo peoples — Hopi, Zuni, and others — who built multi-story adobe apartment complexes, engineered sophisticated irrigation systems in the desert, and maintained trade networks stretching to central Mexico. Their ancestors, the Ancestral Puebloans, had constructed the breathtaking cliff cities at Mesa Verde and Chaco Canyon.

The Pacific Northwest sustained some of the densest populations in pre-contact North America, fed by the extraordinary salmon runs of rivers like the Columbia. Peoples like the Chinook, Haida, and Tlingit developed complex social hierarchies, accumulated substantial wealth, and created some of the most sophisticated art traditions on the continent.

The Haudenosaunee: Democracy Before the Founders

Of all the pre-contact political achievements in North America, the Haudenosaunee Confederacy — the Iroquois League — deserves particular attention, because it directly influenced the political thinking of the people who would eventually write the United States Constitution.

The Haudenosaunee Confederacy was founded, according to oral tradition, by a prophet called the Peacemaker and his spokesperson Hiawatha. They persuaded the five warring nations — Mohawk, Oneida, Onondaga, Cayuga, and Seneca — to lay down their weapons and unite under a Great Law of Peace, the Gayanashagowa.

❝

"We, the people, to form a union, to establish peace, equity, and order among us and our posterity. Hearken to the Words of the Great Law. At the wood's edge of our meeting place, the chiefs of the five nations shall gather and council. No chief shall act independently in matters affecting the confederacy."

The Great Law established a bicameral legislature of sorts — decisions required agreement between the Mohawk, Seneca, and Cayuga on one side, and the Oneida and Cayuga on the other, with the Onondaga serving as a kind of supreme court and final arbiter. Leaders could be impeached. Women clan mothers held the power to appoint and remove male chiefs.

Benjamin Franklin attended Haudenosaunee councils. Historians debate exactly how much the Founders borrowed, but in 1751, Franklin wrote: "It would be a very strange thing if six nations of ignorant savages should be capable of forming a scheme for such a union... and yet that a like union should be impracticable for ten or a dozen English colonies." He called them "ignorant savages" while acknowledging they had built what he wanted to build. That tension — admiration wrapped in contempt — would define Anglo-American relations with Indigenous peoples for the next three centuries.

The Columbian Exchange: A Preview

Before we reach 1492, it is worth understanding what was at stake. The Americas in 1491 contained roughly 60% of the world's agricultural species — corn, potatoes, tomatoes, sweet potatoes, peanuts, squash, peppers, chocolate, vanilla, tobacco. These crops would transform the global food supply within a century of contact.

The Americas also lacked some things that would prove decisive: large domesticated animals (no cattle, horses, pigs, or sheep), and crucially, the diseases that come from living close to livestock for thousands of years. Smallpox, measles, influenza — Eurasian diseases to which Indigenous Americans had no immunity.

When those two things met in 1492 — the unprecedented agricultural wealth of the Americas and the unprecedented biological weapons of Eurasia — the result was the largest demographic catastrophe in human history. Some scholars estimate that 50 to 90 percent of the pre-contact Indigenous population died within 150 years of contact. The "empty wilderness" European settlers saw was, in many cases, land emptied by plague.

"It pleased God to visit these Indians with a great sickness, and such a mortality that of a thousand, above nine and a half hundred of them died, and many of them did rot above ground for want of burial. And the living were not able to bury the dead."

Bradford saw this as God's providence, clearing the land for the Pilgrims. He did not ask why God had sent the disease, or where the disease had come from, or what the people who died had been building before they died. That omission — that refusal to see the full picture — is itself a form of history-making. What you don't ask shapes what you know.

Civilizations the Textbooks Ignore

Most 8th-grade textbooks begin American history in 1492. That choice is not neutral. It defines the starting point as the moment Europeans arrived, which subtly suggests that what happened before Europeans arrived was not really "history" — or at least, not American history.

But the Ancestral Puebloans were building Chaco Canyon's Great House — an 800-room structure aligned to the cardinal directions — while Charlemagne was ruling Europe. The Mississippian cultures were constructing Cahokia while the Normans were invading England. The Haudenosaunee were debating constitutional philosophy while England was still a collection of warring feudal kingdoms.

None of that history disappeared when Columbus landed. It continued, adapted, resisted, and in many ways survived. Understanding it is not just an act of fairness to Indigenous peoples — though it is that. It is also essential to understanding the full story of what became the United States.

What is the 'myth of the empty continent,' and what evidence contradicts it?

▸

The myth holds that North America was essentially wilderness — sparsely populated, unmanaged, unclaimed — before European arrival, which justified colonization as 'settling' empty land. Evidence against it includes: archaeological findings of large cities like Cahokia; sophisticated governance systems like the Haudenosaunee Confederacy; managed landscapes including burned forests and engineered irrigation; extensive trade networks; and demographic evidence suggesting populations of millions. The 'emptiness' Europeans saw was largely the result of epidemic disease that killed up to 90% of the population before sustained European settlement began.
