Slavery in New Spain was based mainly on the importation of slaves from Central Africa and West Africa to work in the colony in the enormous plantations, ranches or mining areas of the viceroyalty, since their physical constitution supposedly made them suitable for working in warm areas.[1]
The largest slave traders in Mexican territory were the Portuguese and the English. The countries that controlled the transatlantic slave market in terms of number of slaves shipped were Great Britain, France, and Portugal.
