- Exploration and Colonization: Ferdinand and Isabella were keen on expanding their territories and establishing colonies in order to increase their wealth, power, and influence. They saw Columbus's voyage as an opportunity to explore new lands, claim territories, and establish colonies in the Americas.
- Economic Motives: The Spanish monarchs were motivated by the potential economic benefits of Columbus's voyage. They hoped to find new sources of wealth, such as gold, silver, spices, and other valuable resources, which would strengthen the Spanish economy.
- Religious Zeal and the Spread of Catholicism: Ferdinand and Isabella were devout Catholics and saw the voyage as a chance to spread Catholicism and convert indigenous peoples to Christianity. They believed in the idea of "saving souls" and saw it as their duty to bring the Catholic faith to the New World.
- Political and Strategic Considerations: Sponsoring Columbus's voyage also served political and strategic purposes for the Spanish monarchs. It allowed them to assert their power and presence in the exploration of the Atlantic and to gain an advantage over their European rivals, particularly Portugal, who were also actively exploring and colonizing at the time.
- Personal Interests and Ambitions: Columbus was a skilled and ambitious navigator who had a strong belief in his ability to reach Asia by sailing west. Ferdinand and Isabella recognized his talent and passion and were willing to support his expedition, driven by their own dreams of discovery, adventure, and the pursuit of personal glory.
