The answer is true, the Crusaders became part of the explorations that helped trade. They learned the routes and new areas for territorial expansion on their journey. It was a violent path of Christian reclamation of land against Muslims that took Jerusalem land. They became the first keys of colonization. Furthermore, they had the opportunity to learn the cultures of other lands which was a benefit on understanding trade and profitable products
