Why was the catholic church stronger in Spain than many other parts of Europe?

The Catholic Church was stronger in Spain than in many other parts of Europe due to the Reconquista, which unified the country under a Catholic monarchy and established a strong alliance between the church and the state. The Catholic Monarchs, Ferdinand and Isabella, actively promoted Catholicism as a national identity, leading to the establishment of the Spanish Inquisition to enforce religious conformity. Additionally, Spain's vast colonial empire spread Catholicism globally, further solidifying the church's influence and power within the country.
