In the 9th century the Muslim Moorish rulers and local Jewish merchants traded in Spanish and Eastern European Christian slaves.
[citation needed] After the "discovery" of the "New World", the Spanish colonialists decided to use it for commercial production and mining because of the absence of trading networks.
[3] The Native American population was used for this labor but they died in large numbers as a result of war, diseases, exploitation and social disruptions.
Bartolomé de las Casas was concerned about the fate of the natives and argued in 1516 that white and black slaves should be imported to the Indies to replace the Amerindians.

[9] In eastern Iberia, in Aragon with its coastal centers of Barcelona and Valencia, slavery evolved in the later Middle Ages.
The imported slaves were non-Christian, or at least non-Catholic, and mostly females who would serve as domestics, referred to as ancillae, and sometimes concubines, within the households of the growing urban centers of eastern Iberia.
As an unintended consequence, this increased the Muslim slave-owners' resistance to assimilation, their faith being reinforced by exposure to slaves from countries where Islam was dominant.

This slave trade was carried out mainly by Spanish merchants as labor for sugar plantations and for domestic service in the American lands, especially in the Caribbean area.
The Spanish privateer and merchant Amaro Pargo (1678–1747) managed to transport slaves to the Caribbean, although, it is estimated, to a lesser extent than other captains and figures of the time dedicated to this activity.
[21] In 1710, the privateer was involved in a complaint by the priest Alonso García Ximénez, who accused him of freeing an African slave named Sebastián, who was transported to Venezuela on one of Amaro's ships.
The aforementioned Alonso García granted a power of attorney on July 18, 1715, to Teodoro Garcés de Salazar so that he could demand his return in Caracas.
