Review Questions

  • How did the marriage of Ferdinand and Isabella contribute to the unification of Spain?
    • The marriage of Ferdinand II of Aragon and Isabella I of Castile was pivotal in unifying Spain as it brought together two powerful kingdoms under a single monarchy. This union allowed for centralized governance, which strengthened royal authority and facilitated reforms across various regions. Additionally, it laid the groundwork for subsequent military campaigns, like the Reconquista, and reinforced their shared vision of a united Catholic Spain.
  • Analyze the role of the Spanish Inquisition in shaping religious policy during the reign of Ferdinand and Isabella.
    • The Spanish Inquisition played a crucial role in enforcing religious orthodoxy during Ferdinand and Isabella's reign by targeting those who were perceived as threats to Catholic unity. By prosecuting converted Jews, Muslims, and other non-Catholics, it sought to eliminate heresy and consolidate power under their rule. The Inquisition also fostered a culture of fear that impacted social dynamics, leading many to either convert or flee from Spain.
  • Evaluate how the actions taken by Ferdinand and Isabella laid the groundwork for Spain's involvement in the transatlantic slave trade.
    • Ferdinand and Isabellaโ€™s decision to support Columbusโ€™s voyages catalyzed Spainโ€™s entry into transatlantic exploration and trade. The discovery of new territories in the Americas opened opportunities for resource extraction and colonization.

Thus, their reign not only unified Spain but also initiated its complex legacy tied to colonialism and the slave trade.
