Of all the rites of Catholic Christendom, that used in the Archdiocese of Braga in the North of Portugal is probably the least known. Perhaps this is due to the fact that Braga is remote and an end in itself, since it is not passed en-route for anywhere else, such as Lyons or Milan, and few books have been written on the subject.

Of late years the retention of this venerable rite has been made the subject of two decrees of the Holy See. In 1919, since a section of the clergy had forsaken its distinctive Liturgy, Pope Benedict XV declared (”Sedis hujus Apostolicæ”) the Rite of Braga to be obligatory throughout the Archdiocese for both Mass and Office, a decree specifically endorsed by the present Pontiff in 1924 (“Inter multiplices gravesque curas”). This last decree finds a place in the preface of the latest addition of the Missal (1924), where the rite is referred to as a “Portuguese glory” (“Lusitania nitidum velut speculum”).

The ecclesiastical importance of Braga dates from the fifth century, when its bishop was advanced to metropolitical rank, as the town, after the destruction of Astorga by the Visigoths (433), had become the capital of the Suevic kingdom.

A distinctive liturgy appears to have been formed— Roman in foundation, with Mozarabic, Gallican and local additions—for in the sixth century we find Bishop Profuturus appealing to the Apostolic See for liturgical guidance. Thus, in 538, Pope Vigilius sent the Church of Braga the Roman Baptismal service, the Canon of the Mass and the proper of Easter to serve as a specimen for the formation of other Masses.
