Final answer:
During the 15th century, around 40,000 Africans were enslaved by the Portuguese and Spanish for plantation work in the Caribbean and Brazil, largely driven by Europe's demand for sugar.
Step-by-step explanation:
In the last half of the fifteenth century some forty thousand Africans were forced into slavery by Portuguese and Spanish traders to work on plantations in the Caribbean and Brazil. The insatiable European demand for sugar fueled the growth of plantations, resulting in an increased demand for enslaved laborers.
By the seventeenth century, as England, France, the Netherlands, and Denmark established more sugar plantations, the horrific practice of enslavement grew, and the number of Africans transported across the Atlantic, known as the Middle Passage, escalated.
Throughout the sixteenth to nineteenth centuries, millions of Africans were forcibly transported to the Americas, enduring brutal conditions and resistance was met with severe violence.
