Crusader Orders were military and religious groups formed during the Crusades, which were a series of religious wars in the medieval period aimed at reclaiming the Holy Land from Muslim control. These orders combined the roles of knights and monks, emphasizing both martial prowess and spiritual devotion. Notable examples include the Knights Templar and the Knights Hospitaller. These orders provided protection for pilgrims and fought in battles, often establishing strongholds in the Levant. They also engaged in charitable activities, such as caring for the sick and poor. Over time, their influence grew, leading to significant political and economic power in Europe and the Middle East.
