The Gallican Rite is a historical version of Christian liturgy and other ritual practices in Western Christianity. It is not a single rite but a family of rites within the Latin Church, which comprised the majority use of most of Western Christianity for the greater part of the 1st millennium AD. The rites first developed in the early centuries as the Syriac-Greek rites of Jerusalem and Antioch and were first translated into Latin in various parts of the Western Roman Empire Praetorian prefecture of Gaul. By the 5th century, it was well established in the Roman civil diocese of Gaul, an early center of Christianity. Ireland is also known to have had a form of this Gallican Liturgy mixed with Celtic customs.
