The coronation of King Charles III will follow longstanding traditions and will be conducted by the Archbishop of Canterbury at Westminster Abbey, the same location used for coronations since 1066. The ceremony is a religious one, acknowledging the monarch's dual role as both head of state and head of the Church of England. The Archbishop will proclaim the King "the undoubted King" during the Recognition stage, while the King will make an oath and sign a pledge to serve the people and rule according to law during the Coronation Oath stage. The anointing, investiture, which includes the crowning, and the homage are also key stages of the coronation. The Queen Consort, Camilla, will also be crowned during the ceremony. The Liber Regalis, a medieval Latin manuscript, has laid out the order of service for coronations since the late 14th century. Celebrity guests and international political figures attended the ceremony, including Emma Thompson, Dame Judi Dench, Joanna Lumley, and First Lady of the United States, Jill Biden.
