What elements of spanish worldview were used to justify the expansion of the spanish empire?

The Spanish worldview was influenced by the belief in the superiority of their religion and culture, which they used to justify spreading Christianity and "civilizing" indigenous populations. They believed in the concept of "divine right" to conquer and claim new territories under the authority of the Catholic monarchs. Additionally, there was a strong emphasis on accumulating wealth and resources as a measure of power and prestige, driving the desire to expand the empire.
