Desire for Exploration: Columbus presented a bold idea of reaching Asia by sailing west, which intrigued the Spanish monarchs. They saw this journey as an opportunity to expand their kingdom and explore new territories, potentially increasing their wealth and power.
Religious Motives: Isabella I, in particular, had deep religious convictions and aimed to spread Christianity to far-off lands. Columbus's plan offered the possibility of reaching previously unknown lands and introducing Catholicism to the indigenous people he might encounter.
Economic Incentives: The potential for economic gains was also a significant factor. Spices, gold, and other valuable commodities were highly sought after in Europe, and Columbus's proposal promised access to those riches in the East.
Technological Advancements: The development of more advanced ships and navigational instruments at the time made the idea of a long-distance voyage seem more feasible. This encouraged Isabella and Ferdinand to support Columbus's ambitious expedition.
Competition with Other European Nations: Spain was facing competition from its European rivals, particularly Portugal, in terms of exploration and territorial expansion. By supporting Columbus's journey, the Spanish monarchs hoped to gain a strategic advantage and outdo their rivals in acquiring wealth and new lands.
Isabella and Ferdinand carefully assessed the risks and potential rewards of Columbus's proposed journey, and they ultimately decided that the potential benefits outweighed the costs and risks. Thus, they agreed to fund the expedition, setting the stage for Columbus's voyage and the subsequent discoveries that changed the course of history.
