The Order of Merit is a Portuguese Honorific Order of civil merit intended to award those responsible for meritorious acts or services performed in the exercise of any functions, both in the public and the private sphere, which reveal self-sacrifice in favor of the community. The decorations are given by the President of the Portuguese Republic, in his role as the Grand-Master of the Portuguese Honorific Orders. The Order of Merit can be awarded, during life or posthumously, to both Portuguese and foreign citizens; it can also be awarded to localities or institutions that are legal persons governed by public law or of public utility. This order has been awarded to a number of people performing the most diverse functions such as ambassadors, businesspeople, military personnel, athletes and musicians.
