In 973, Dunstan's statesmanship reached its zenith when he officiated at the coronation of King Edgar. Edgar was crowned at Bath in an imperial ceremony planned not as the initiation, but as the culmination of his reign (a move that must have taken a great deal of preliminary diplomacy). This service, devised by Dunstan himself and celebrated with a poem in the "Anglo-Saxon Chronicle" forms the basis of the present-day British coronation ceremony. There was a second symbolic coronation held later. This was an important step, as other kings of Britain came and gave their allegiance to Edgar at Chester. Six kings in Britain, including the kings of Scotland and of Strathclyde, pledged their faith that they would be the king's liege-men on sea and land.
