How did the spanish reconquista affect culumbus's expidiition?

The Spanish Reconquista, completed in 1492 with the capture of Granada, unified Spain under Catholic rule and strengthened the monarchy's ambitions for exploration. This newfound unity and nationalism, coupled with the desire to spread Christianity, motivated King Ferdinand and Queen Isabella to sponsor Christopher Columbus's expedition. They sought new trade routes and territories, which ultimately led to Columbus's discovery of the Americas. The Reconquista's completion also instilled a sense of confidence and urgency in the Spanish crown to expand its influence globally.
