Final answer:
The Roman Catholic Church supported the Reconquista by recruiting soldiers and sending monks to join the army.
Step-by-step explanation:
The Roman Catholic Church supported the Reconquista through various means. One of the ways was by recruiting soldiers. The church played a significant role in raising armies and encouraging people to join the fight against the Muslim rulers in al-Andalus. They also helped in organizing and funding military campaigns.
Additionally, the Catholic Church sent monks to join the army. These monks acted as spiritual guides and encouraged the soldiers to fight for the faith and defend Christianity. They provided moral support and played a crucial role in boosting the morale of the troops.
It's important to note that while the church supported the Reconquista, excommunication of generals or stopping taxing people are not specifically mentioned as ways the Roman Catholic Church supported the Reconquista.
