The accession of the king of France to the royal throne was legitimized by a ceremony performed with the Crown of Charlemagne at the Reims Cathedral. In late medieval and early modern times, the new king did not need to be anointed in order to be recognized as French monarch but ascended upon the previous monarch's death with the proclamation "Le Roi est mort, vive le Roi!"
The most important part of the French ceremony was not the coronation itself, but the Sacre – the anointing or unction of the king. The Carolingian king Pepin the Short was anointed in Soissons (752) to legitimize the accession of the new dynasty. A second anointing of Pepin by Pope Stephen II took place at the Basilica of Saint-Denis in 754, the first to be performed by a pope. The unction served as a reminder of the baptism of king Clovis I in Reims by archbishop Saint Remi in 496/499, where the ceremony was finally transferred in 816 and completed with the use of the Holy Ampulla found in 869 in the grave of the Saint. Since this Roman glass vial containing the balm due to be mixed with chrism, was allegedly brought by the dove of the Holy Spirit, the French monarchs claimed to receive their power by divine right. Out of respect for the miraculous oil, the king's shirt and the gloves put on after the unction of the hands were burned after the ceremony. Exceptionally, the shirt worn by Louis XV was not burned. The shirt was donated to the king of Portugal, John V, and is today at the National Palace of Mafra, guarded by the Royal and Venerable Confraternity of the Most Blessed Sacrament of Mafra.
