Tents were widely used in the middle ages for military campaigns. Crusaders and their Arab counterparts both used tents during the crusades. Tents were also used when people assembled for tournaments or other occasions. The tents were made of canvas, duck, wool, linen and even leather. Painting the tents might have provided some degree of waterproofing. Tents often were brightly colored and nobles often displayed their arms on tents. Inside there could be silk or wool hangings.
