The Pilgrims were a group of approximately 100 people who in 1620 sailed on the Mayflower ship to North America, known then as the New World from England; they were seeking freedom from religious oppression. The party landed at present-day Cape Cod, Mass and created a settlement at Plymouth Harbor.
As History.com points out, though Christopher Columbus did not discover the New World, one of the impacts of his exploration was the opening of the North America to settlement and exploitation. Another impact was the devastation of the native population through disease, subjugation and environmental deterioration.
There were many advantages and disadvantages to Columbus's travels to America, including the pro of advancing trade and the con of disrupting the lives of indigenous people. When Christopher Columbus arrived in the Caribbean, he made communication and trade possible between Europe and the Americas. Known as the Columbian Exchange, the transfer of food, animals, language, religion, and disease greatly benefited Europe and destroyed American indigenous cultures at the same time.
