Lesson 3: The Columbian Exchange

The contact between the Old World (Europe/Africa/Asia) and the New World (Americas) triggered the Columbian Exchange—the global transfer of foods, plants, and animals. The Americas gave the world Corn and Potatoes, nutrient-rich crops that boosted populations in Europe and China.

In return, Europeans brought Horses, cattle, and pigs to the Americas, transforming Native American lifestyles. However, they also brought invisible killers: diseases like Smallpox and measles. Native Americans had no natural immunity, and millions died (up to 90% of the population in some areas), causing the collapse of civilizations like the Aztec and Inca.

The wealth flowing from colonies changed Europe's economy. Nations adopted an economic policy called Mercantilism, which held that a country's power depended on its wealth (gold and silver). The goal was to export more than you import. Colonies were vital because they provided raw materials and a market for finished goods.

At the same time, Capitalism emerged. This system is based on private ownership and the investment of money for profit. Merchants, not just nobles, began to grow rich. They formed Joint-Stock Companies to fund expensive voyages, sharing both the risks and the profits of colonization.

European colonists in the Americas established huge Plantations to grow cash crops like sugar and tobacco. Initially, they tried to enslave Native Americans, but the indigenous people died rapidly from disease.

To replace this labor force, Europeans turned to Africa. Unlike earlier forms of slavery, the Atlantic Slave Trade was based on race and was hereditary (children of slaves were also slaves). This system, known as Chattel Slavery, treated human beings as property to be bought and sold, dehumanizing millions of Africans to fuel the European economy.
