By 1517, the Spaniards realized that the remaining Natives were not enough to continue the hard labor they've subjugated them to; in just 15 years, their rapacity succeeded in the complete genocide of the peaceful Taino/Arawak population. Labor shortage and greed forced the Spaniards to begin the importation of men and women from the African Continent. Haiti became the first country in the new world to welcome black men, women and children from Africa; as slaves.
The slave trade became the first institution of modern times in which labor power was bought and sold on a large scale. But the Spaniards soon started to abandon the importation of slaves from Africa to the island, as they have now discovered new land in Peru.
