Answer:
Last Option: Spread Christianity to Indigenous people.
What were the reasons the Spanish conquered the Americas?
In 1492, Spain made contact with the New World. India was assumed to be the location of the Fresh World because Christopher Columbus, the Spanish expedition's leader, attempted to sail to India, creating a new path to the uncharted West rather than the already-traveled and Portugal-dominated East. The new territory was claimed by the Catholic Kings Isabel de Castilla and Fernando de Aragón on behalf of the Kingdom of Castile, which had funded the expedition of three ships, La Pinta, La Nia, and La Santa Mara. The new land was known as Las Indias Occidentales, and the natives were known as Indians. Later on, it was discovered that it wasn't India, but rather a sizable new continent that was given the name of America. The regions the Spaniards found and conquered in America were acquired by the Spanish Crown and added to its Kingdom.
