1. Eastern knowledge and scholarship: Crusaders were exposed to the advanced knowledge and scholarship of the Eastern cultures they encountered, including Islamic, Byzantine, and Persian civilizations. This exposure to Eastern knowledge had a profound impact on European learning, particularly in the fields of mathematics, astronomy, medicine, and philosophy.

2. Trade routes and goods: The Crusades facilitated the establishment of direct trade routes between Europe and the East. As a result, European crusaders came into contact with various valuable goods, spices, textiles, and luxury items from the East. This sparked the interest in indulgences and influenced future European trade and commerce.

The Crusades introduced Europeans to innovative architectural techniques, construction methods, and engineering skills that were later incorporated into European architecture.

4. Cultural exchange: The interactions between European crusaders and Middle Eastern cultures fostered cultural exchange. Crusaders were exposed to new ideas, languages, literature, music, and art. These cultural influences had a lasting impact on European society and artistic expression.

5. Military tactics and technology: Crusaders encountered advanced military tactics, weapons, and technologies employed by the Muslim armies. They learned from these encounters and adopted and adapted various aspects of Eastern military strategies, leading to advancements in European warfare.
