Answer:
To spread the message of Christianity.
To bring back gold to Spain.
Explanation:
These are two of the reasons why Spain was interested in establishing colonies in the Americas. Spain was interested in spreading Christianity, as they believed this to be the only path to salvation. Priests were some of the first people to arrive to the colonies, encouraged by the extremely religious Isabella and Ferdinand. Another reason for the establishment of colonies was to bring back gold to Spain. Enormous quantities of gold were extracted from the continent, as well as silver, precious stones and other goods.
