Final answer:
The Crusades impacted Muslim empires through the loss of land in modern-day Spain and the advancement in culture.
Step-by-step explanation:
The Crusades had a significant impact on the Muslim empires. One major consequence was the loss of land in modern-day Spain, specifically the Islamic territories collectively known as Al-Andalus. These territories were gradually taken over by Christian kingdoms during the Reconquista, which was partially fueled by the religious fervor and military experience of the Crusades. Another impact was the advancement in culture, as the Crusades brought people from different cultures and backgrounds into contact with each other, leading to new ideas, trade, and exchange of knowledge.
