In 1006, Ælfheah succeeded Ælfric as Archbishop of Canterbury, taking Swithun's head with him as a relic for the new location. He went to Rome in 1007 to receive his pallium—symbol of his status as an archbishop—from Pope John XVIII, but was robbed during his journey. While at Canterbury, he promoted the cult of Dunstan, ordering the writing of the second "Life of Dunstan", which Adelard of Ghent composed between 1006 and 1011. He also introduced new practices into the liturgy, and was instrumental in the Witenagemot's recognition of Wulfsige of Sherborne as a saint in about 1012.
