The first of the Orders of Knighthood were the military orders of crusaders who used red, green or black crosses of velvet on their mantles, to distinguish their brotherhoods. Later the members of knightly orders used rings, embroidered dragons and even garters as the symbol of their order. In the late Middle Ages the knights wore their insignia ever more prominently and medaillons, crosses and jewels in the shape of animals began to be worn on chains around the neck, known as livery collars. After the 17th century the heyday of the collar was over. They were worn only on ceremonial occasions and replaced in daily life by stars pinned to the breast, and badges suspended from ribbons. Many orders retained their collars and when orders were divided into several ranks or grades the collar was usually reserved for the highest rank. The notable exception is Portugal.
