Detailed explanation-1: -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-2: -Portuguese mariners sailed beyond Cape Bojador, Morocco, for the first time in the 1430s. By 1445, a trading post was established on the small island of Arguim off the coast of present-day Mauritania.

Detailed explanation-3: -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-4: -The transatlantic slave trade had its beginning in the middle of the fifteenth century when Portuguese ships sailed down the West African coast. The intention was to trade for gold and spices, but the voyagers found another even more valuable commodity-human beings.
