Coronation of the British monarch [SEP] Development of the English coronation
The main elements of the coronation service and the earliest form of oath can be traced to the ceremony devised by Saint Dunstan for Edgar's coronation in 973 AD at Bath Abbey. It drew on ceremonies used by the kings of the Franks and those used in the ordination of bishops. Two versions of coronation services, known as "ordines" (from the Latin "ordo" meaning "order") or s, survive from before the Norman Conquest. It is not known if the first recension was ever used in England and it was the second recension which was used by Edgar in 973 and by subsequent Anglo-Saxon and early Norman kings.
