The Gallican Rite is a historical sub-grouping of the Roman Catholic liturgy in western Europe; it is not a single rite but actually a family of rites within the Western Rite which comprised the majority use of most of Christianity in western Europe for the greater part of the 1st millennium AD. The rites were first developed in the early centuries as the Syriac-Greek rites of Jerusalem and Antioch were first translated into Latin in various parts of the Roman West. It was well established by the 5th century in Gaul. Ireland too is known to have had a form of this Gallican Liturgy mixed with Celtic customes. The rites can be considered part of what is now the Western branch of the Catholic Church. Today, a rite of this family is still in use in the Archdiocese of Lyon, France.
