USA HISTORY

Detailed explanation-1: -The first voyage carrying enslaved people direct from Africa to the Americas probably sailed in 1526. The number of people carried off from Africa reached 30, 000 per year in the 1690s and 85, 000 per year a century later.

Detailed explanation-2: -In the fifteenth century, Portugal became the first European nation to take significant part in African slave trading. The Portuguese primarily acquired slaves for labor on Atlantic African island plantations, and later for plantations in Brazil and the Caribbean, though they also sent a small number to Europe.

Detailed explanation-3: -The high demand for slaves was due to a shortage of laborers in Portugal. Black slaves were in higher demand than Moorish slaves because they were much easier to convert to Christianity and less likely to escape.

Detailed explanation-4: -The most momentous discovery in western Africa, however, came in 1471, when Portuguese captains first reached the coast of modern Ghana between the mouths of the Ankobra and Volta rivers.
