An order is a visible honour awarded by a sovereign state, monarch, dynastic royal house or organisation to a recipient, typically in recognition of individual , that often comes with distinctive insignia such as collars, medals, badges, and sashes worn by recipients.
Modern honour systems of state orders and dynastic orders emerged from the culture of orders of chivalry of the Middle Ages, which in turn emerged from the Catholic religious orders.
The word order (Latin: ordo), in the case referred to in this article, can be traced back to the chivalric orders, including the military orders, which in turn trace the name of their organisation back to that of the Catholic religious orders.
Orders began to be created ad hoc and in a more courtly nature. Some were merely honorary and gradually the badges of these orders (i.e. the association) began to be known informally as orders. As a result, the modern distinction between orders and decorations or insignia has become somewhat blurred. While some orders today retain the original notion of being an association or society of individuals, others make no distinction and an "order" may even be the name of a decoration.
Most historic chivalric orders imply a membership in a group, typically a confraternity. In a few exclusive European orders, membership is or was also limited in number. Decorations seldom have such limitations. Orders often come in multiple classes, including knights and dames in imitation of the original chivalric orders.
