Step-by-step explanation:
In the writings of Columbus, Cortes, and de las Casas, the motives of God, glory, and gold are made evident through their focus on economic gain and spreading Christianity. Columbus, in his descriptions of his discoveries, emphasized the amount of gold the new continent contained. Cortes hoped to gain hereditary privilege, tribute payments, and labor from natives, as well as the wealth in gold possessed by the Aztecs. De las Casas wrote about the destruction of indigenous populations and the economic exchange of gold and resources.
