Question

What caused Spain's and Portugal's demands for African slaves to grow?

Answer 1

Answer:

The Spanish and Portuguese were in need of colonial labor force so they had to increase the source for African slaves.

Explanation:

Demand for African slaves was high and the slave trade was controlled by the Portuguese, who set up trading posts on the west coast of Africa. Spanish colonists purchased them directly from Portuguese traders, who in turn purchased them from African traders on the Atlantic coast.

As a result, it was Spain, rather than Portugal, that first made extensive use of enslaved Africans as a colonial labor force.

Answer 2

The decrease in indigenous people in the newly explored lands, an increase in agricultural production.
