Remigius was the Bishop of Reims and "Apostle of the Franks". On 25 December 496, he baptised Clovis I, King of the Franks. The baptism, leading to about 3000 additional converts, was an important event in the Christianization of the Franks. Because of Clovis's efforts, a large number of churches were established in the formerly pagan lands of the Frankish empire, establishing a distinctly Orthodox variety of Christianity for the first time in Germanic lands, most of whom had been converted to Arian Christianity.

The Archdiocese of Reims is a Latin Church ecclesiastic territory or archdiocese of the Catholic Church in France. Erected as a diocese around 250 by St. Sixtus of Reims, the diocese was elevated to an archdiocese around 750. The archbishop received the title "primate of Gallia Belgica" in 1089.
