If that wasnt enough of a history lesson here you go:
Genocide of indigenous peoples - Wikipedia
Spanish colonization of the Americas[edit]

Brevisima relación de la destrucción de las Indias, depicting Spanish atrocities during the
conquest of Cuba
It is estimated that during the initial
Spanish conquest of the Americas up to eight million indigenous people died, marking the first large-scale act of genocide of the modern era.
[29] Acts of brutality in the Caribbean and the systematic annihilation occurring on the
Caribbean islands prompted
Dominican friar
Bartolomé de las Casas to write
Brevísima relación de la destrucción de las Indias ("
A Short Account of the Destruction of the Indies") in 1552. Las Casas wrote that the indigenous population on the Spanish colony of
Hispaniola had been reduced from 400,000 to 200 in a few decades.
[30] His writings were among those that gave rise to
Leyenda Negra (Black Legend) to describe Spanish cruelty in the Indies.
[31] Noble David Cook, writing about the Black Legend and the conquest of the Americas wrote, "There were too few Spaniards to have killed the millions who were reported to have died in the first century after Old and New World contact" and instead suggests the near total decimation of the indigenous population of Hispaniola as mostly having been caused by diseases like smallpox.

With the initial conquest of the Americas completed, the Spanish implemented the
encomienda system. In theory, encomienda placed groups of indigenous peoples under Spanish oversight to foster cultural assimilation and
conversion to Christianity, but in practice led to the legally sanctioned exploitation of natural resources and forced labor under brutal conditions with a high death rate. Though the Spaniards did not set out to exterminate the indigenous peoples, believing their numbers to be inexhaustible, their actions led to the annihilation of entire tribes such as the
Arawak.
[33] In the 1760s, an expedition despatched to fortify California, led by
Gaspar de Portolà and
Junípero Serra, was marked by slavery,
forced conversions and genocide through the introduction of disease.
