What is the
Columbian Exchange?
The Columbian exchange is the widespread trade that took place after the "discovery" of the New World.
Animals, crops, dieases, and people were exchanged shifting the course of world history.
After Columbus
Columbus returned to Europe and told of a vast land rich with resources.
This attracted many other Europeans to the New World due to:
God - wanted to spread Christianity
Glory - Reach immortality as a famous explorer
Gold - become rich.
Effects on People
Europeans used superior weapons to gain control of the native populations during wars.
guns vs. bows & arrows.
Many natives also died from European Disease
Europeans brought diseases with them to new world.
Natives had no immunity due to lack of domesticated animals.
led to massive depopulation of natives
Natives were also forced into slave labor on plantations.
Depopulation of natives due to wars, disease, and slavery led to the importation of African slaves.
Depopulation of the Native Americans
Due to the importation of European diseases, the native population declined by as much as 24 million indians in 75 years ~ 80% just from diseases.
Indigenous Depopulation
According to some estimates, 95% of the native population of the America's that came in contact with Europeans died within 130 years of Columbus' discovery of America.
Effects on the Plants
