Answer:
10 million
Step-by-step explanation:
With the discovery of the New World, slavery took on another form, when the Portuguese and Spanish learned that sugar cane grew very well in Brazil and the Caribbean Islands. At first, they tried using the native populations. But epidemics of disease killed off many of the indigenous populations. So the settlers traded for slaves from Africa who could be bought cheaply. Soon, thousands of slaves were being shipped to the New World each year. It is believed that more than ten million people were taken from Africa as slaves over a thousand-year span ending in the nineteenth century.
