Who was the original workforce in new Spain?

The Viceroyalty of New Spain was a colonial administrative entity belonging to Spain, which existed in the territory of what is now the southeast of the United States, Mexico and Central America between the years 1535 and 1821. This viceroyalty was the main Spanish colony in the American continent, both in economic and political terms.

Its economy was based fundamentally on the exploitation of raw materials, and in particular, on the exploitation of precious metals such as gold and silver, which were taken to Spain to mint money and thus increase the treasury coffers of the crown.

In order to carry out this exploitation, the first labor used was that of the natives, who were used through the Encomienda system as quasi slaves, that is, free labor in exchange for "evangelization". Later, they were joined by African slaves who were taken to the continent to carry out these tasks.

regarding the law, the 15th amendment was specifically designed thinking in the rights of black free men.

even though ratified on february 3, 1870, the promise of the 15th amendment would not be fully applied for a long time.poll taxes and literacy tests would allow southern states disenfranchise african americans. only in 1965 the voting rights for african americans would be actually able to vote in the south.

in 1965, president johnson signed the voting rights act, which aimed to overcome legal barriers that prevented african americans from voting as it was guaranteed by the 15th amendment to the u.s. constitution.
