Answer:
About 366 years
Step-by-step explanation:
From the time the Portuguese first arrived until slavery was outlawed in the New World, there existed a West African slave trade. Before 1492, the Portuguese began importing slaves from Africa. The demand for slaves and the slave trade skyrocketed after 1492. Brazil did not abolitionize slavery until 1888. Even when the slave trade was outlawed in country after country, some slave traffickers continued to operate in violation of the law in order to profit.
