In 1520, King Charles I of Spain issued a royal decree collectively emancipating the remaining Taíno population. By that time, the Taíno people were few in number. Enslaved Africans had already begun to be imported to compensate for the native labor loss, but their numbers were proportionate to the diminished commercial interest Spain soon began to demonstrate for the island colony. Other nearby islands, like Cuba, Hispaniola, and Guadalupe, attracted more of the slave trade than Puerto Rico, probably because of greater agricultural interests in those islands, on which colonists had developed large sugar plantations and had the capital to invest in the Atlantic slave trade.
