America Before Columbus: The Untold Story of the New World | Extra Long Documentary

Summary

The documentary argues that the Americas in 1491 were not an empty or untouched wilderness. They supported large populations, diverse societies, and deliberately managed landscapes. The arrival of Columbus and the later movement of people, plants, animals, and diseases between the Americas and Europe transformed both continents, though the changes were especially devastating in the Americas.

The Americas Before Columbus

• The Americas contained many different societies, from farming and fishing communities to cities, kingdoms, and empires. The documentary estimates their population at about 100 million.
• Major civilizations included the Mississippian mound-building societies, the Inca Empire in the Andes, the Aztecs in Mesoamerica, the Anasazi in the Southwest, and settled communities in the Amazon region.
• American agriculture relied on crops domesticated over long periods. Corn supported large populations in parts of North America, while potatoes were central to life in the Andes.
• Inca farmers grew many varieties of potato, built mountain terraces to conserve soil and cultivate crops at high elevations, and preserved potatoes as chuño for storage.
• Indigenous peoples also shaped their environments. On the Plains, communities deliberately burned grasslands and undergrowth to encourage fresh grazing and make hunting easier. The documentary stresses that the landscape was managed, not pristine.

Differences Between American and European Food Systems

• European agriculture combined grain cultivation with livestock. Animals supplied meat, milk, hides, manure, and draft power, while ploughs, carts, and animal power helped produce food on limited land.
• Most American societies had fewer large domesticated animals. Llamas provided wool, hides, manure, and some transport in the Andes, but could not be ridden or used to pull ploughs. Turkeys were important in Mesoamerica.
• The documentary links the scarcity of domesticable large mammals to the extinction of much American megafauna after the Ice Age, attributing the extinction to both climate change and hunting.
• European landscapes were already heavily altered by farming, cities, timber use, and fishing. Rivers had been affected by sediment and dams, while forests were heavily exploited for fuel, construction, ships, and war.

Environmental Change and the Limits of Resource Use

• The documentary challenges the idea that Indigenous societies always lived in perfect harmony with nature.
• It presents Chaco Canyon as an example of environmental pressures contributing to societal decline. The Anasazi built large settlements, but deforestation, erosion, drought, and population pressure may have made agriculture unsustainable. The documentary notes that climate change and overharvesting may both have contributed.
• The documentary also describes the Amazon as a more densely settled and deliberately modified landscape in the past, with orchards, settlements, causeways, canals, and fire-managed grasslands.
• Europe, too, had depleted resources: forests were cut for buildings and ships, and freshwater fish populations declined due to agricultural sediment and dams. Europeans increasingly relied on marine fishing.

Columbus and the Beginning of Conquest

• Columbus sought a westward route to Asian trade and eventually secured support from Queen Isabella of Spain.
• His first voyage reached the Caribbean in 1492, though he believed he had reached Asia. The documentary presents the voyage as the beginning of European conquest and colonization, not the discovery of an empty land.
• Columbus’s report of the lands and riches he encountered circulated widely in Europe, encouraging more people to seek wealth and opportunity overseas.
• Later Spanish expeditions brought soldiers and settlers, and the horse gave the Spanish a major military and practical advantage. The documentary describes the fall of the Aztec and Inca empires within a few decades.

The Biological Exchange

The documentary’s central theme is that conquest was accompanied by a vast transfer of living things, often called the Columbian Exchange.

• Animals brought to the Americas: Horses, pigs, cattle, sheep, goats, and chickens spread across the continent. Horses later became central to the lives of many Plains peoples. Feral pigs damaged Indigenous crops, while livestock and European weeds reshaped ecosystems.
• Plants brought to the Americas: Europeans introduced grains such as wheat, barley, oats, and rye, along with fruit trees and other crops. The documentary describes European livestock and agriculture as transforming forests and grasslands into pastures and farms.
• American crops brought to Europe: Corn, chili peppers, pumpkins, tomatoes, and potatoes crossed the Atlantic. Potatoes eventually became a major European food, helping support population growth; the turkey also entered European diets.
• The exchange was uneven. The documentary attributes this partly to the catastrophic decline of Indigenous populations in the Americas, which created ecological and economic openings for European crops, animals, and weeds. Europe’s population, by contrast, was not similarly reduced by introduced diseases.

Disease, Slavery, and Colonial Economies

• Diseases such as smallpox, measles, and influenza spread among Indigenous populations, often faster than European explorers. The documentary says that Native peoples had no prior immunity and that estimates of mortality range from about 50% to 90% or more.
• The resulting population collapse made it harder for Indigenous communities to maintain their societies and land-management systems. The documentary estimates that roughly 90% of Native Americans died during the broader period of conquest and colonization.
• The documentary also describes syphilis as a disease carried from the Americas to Europe.
• European colonists developed large plantations for commodities such as sugar, tobacco, rice, and cotton. To meet colonial labor demands amid Indigenous depopulation, Europeans forcibly transported millions of Africans and enslaved them.
• The documentary concludes that the modern Americas were shaped not only by migration and conquest but also by ecological changes: crops, livestock, weeds, and microbes helped make European settlement possible.

Methods and Practices Described

• Making chuño for long-term storage: Potatoes were spread out to freeze overnight, exposed to sunlight during the day, and trampled to remove water. The dried product could be stored for years as protection against crop failures.
• Building Andean terraces: Farmers cut step-like plots into mountainsides to reduce soil erosion, create level ground, and capture more sunlight for crops.
• Managing grasslands with fire: Indigenous communities burned undergrowth and prairie areas to encourage fresh grass, attract grazing animals, and improve hunting conditions.
• Investigating past environments:
  • Researchers examine packrat middens—nests containing preserved plant remains, seeds, and sometimes archaeological fragments—to reconstruct the local ecology at particular times.
  • Dendrochronologists count tree rings in old logs to date when trees were cut and track changes in construction and woodland use.
• Explaining fish declines: The documentary describes how agricultural sediment clouded rivers and dams blocked migratory fish, while later commercial fishing depleted marine stocks.
