The Order of Prince Henry (Portuguese: Ordem do Infante Dom Henrique) is a Portuguese order of knighthood created on 2 June 1960, to commemorate the quincentenary of the death of the Portuguese infante Prince Henry the Navigator, one of the main initiators of the Age of Discovery. Minor reforms of the constitution of the Order occurred in 1962 and 1980. It is a five-tier order, whose titles are awarded for relevant services to Portugal and for services in the expansion of the Portuguese culture, its history and its values (with a particular focus on its maritime history). The number of members in each grade is restricted by its constitution, and titles are conferred by special decree by the Grand Master of the Order, i.e., the President of Portugal.
