Before the Europeans arrived in the Americas, there were many American Indian tribes scattered across North and South America. These tribes had complex societies with unique religious, political, and cultural beliefs.
European countries sought to conquer the New World in order to gain wealth and military status, and to spread the ideas of Christianity. European exploration often resulted in negative consequences for native populations, such as widespread epidemics and forced labor systems like the Spanish encomienda system.
Relationships between the Europeans and American Indians were often fraught with misunderstandings and conflict regarding not only land and resources but also differing cultural beliefs.
The Columbian Exchange resulted in tremendous social, cultural, and political change for both the Europeans and the American Indians. New food crops and new sources of mineral wealth brought about extensive demographic, economic, and social change in Europe. The introduction of new food crops and animals also impacted the Americas.
As native populations dwindled, Europeans turned to Africa as a new source of forced labor, giving rise to the early plantation system and widespread system of slavery in the Americas.
