Unit 7 Notes

What was the Columbian Exchange?

• The explorers created contact between Europe & the Americas.

• Interaction with Native Americans led to big cultural changes.

• Exchange of people, animals, plants, diseases, weapons, ideas, etc.

The Columbian Exchange

The introduction of beasts of burden to the Americas was a significant development from the Columbian Exchange. The introduction of the horse provided people in the Americas with a new source of labor and transportation.

• Explorers created contact between Europe and Americas.

• Interaction with Native Americans led to big cultural changes.

• Contact between the two groups led to the exchange of people, ideas, plants, animals, and disease—the Columbian Exchange.

• Plants, animals developed in very different ways in hemispheres

• Europeans—no potatoes, corn, sweet potatoes, turkeys

• People in Americas—no coffee, oranges, rice, wheat, sheep, cattle

The Exchange of Goods

The Columbian Exchange

• Arrival of Europeans in Americas changed all this

• Previously unknown foods taken back to Europe

• Familiar foods brought to Americas by colonists

Sharing Discoveries

Different Foods

• Exchange of foods, animals had dramatic impact on later societies

• Over time crops native to Americas became staples in diets of Europeans

• Foods provided nutrition, helped people live longer

Italian Food Without Tomatoes?

• Until contact with Americas, Europeans had never tried tomatoes

• Most Europeans thought tomatoes poisonous

• By late 1600s, tomatoes had begun to be included in Italian cookbooks

Economics and Diets

EffectsEffects of the Columbian Exchange

• Effects of Columbian Exchange felt not only in Europe, Americas

• China– Arrival of easy-to-grow, nutritious corn helped

population grow tremendously– Also a main consumer of silver mined in Americas

• Africa – Two native crops of Americas—corn, peanuts—still

among most widely grown • Scholars estimate one-third of all food crops

grown in world are of American origin

Devastating Impact

• Native American population continued to decline for centuries

• Inca Empire decreased from 13 million in 1492 to 2 million in 1600

• North American population fell from 2 million in 1492 to 500,000 in 1900—but disease not only factor in decrease of population

• Intermittent warfare, other violence also contributed

The Introduction of New DiseasesNew Diseases

• Native Americans had no natural resistance to European diseases

• Smallpox, measles, influenza, malaria killed millions

• Population of central Mexico may have decreased by decreased by more than 30 percent in the 10 years following first contact with Europeans
