Answer: During the Crusades, Europeans gained knowledge and technologies from the Muslim world, which helped spur economic growth and development in Europe, and laid the foundation for the Renaissance. Europeans also increased trade and commerce with the Muslim world through the acquisition of luxury goods.
Explanation: One way that Europeans benefited from increased contact with the Muslim world during the Crusades was through the introduction of new ideas, technologies, and products. The Crusaders came into contact with Muslim scholars, scientists, and traders who had advanced knowledge in fields such as mathematics, astronomy, medicine, and architecture. Europeans learned from Muslims and adopted many of their ideas and technologies, such as Arabic numerals, the astrolabe, and advances in medicine. These innovations helped to spur economic growth and development in Europe, and laid the foundation for the Renaissance. Additionally, the Crusaders brought back luxury goods such as spices, textiles, and ceramics from the Muslim world, which increased trade and commerce in Europe.
