The slave trade was an important part of the economy of the Americas in the 1700s. Slaves were captured in Africa and sent to the colonies of America as workers. The journey was dangerous, and more than one-third died in those terrible conditions. Upon arrival, slaves were mostly sent to the colonies of the Caribbean, Brazil, and Southern United States. Although many colonial powers participated, slavery was mostly abolished when the new nations gained independence, with the exception of the United States.
