Passage: The Great Officers of State traditionally participate during the ceremony. The offices of Lord High Steward and Lord High Constable have not been regularly filled since the 15th and 16th centuries respectively; they are, however, revived for coronation ceremonies. The Lord Great Chamberlain enrobes the sovereign with the ceremonial vestments, with the aid of the Groom of the Robes and the Master (in the case of a king) or Mistress (in the case of a queen) of the Robes.The Barons of the Cinque Ports also participated in the ceremony. Formerly, the barons were the members of the House of Commons representing the Cinque Ports of Hastings, New Romney, Hythe, Dover and Sandwich. Reforms in the 19th century, however, integrated the Cinque Ports into a regular constituency system applied throughout the nation. At later coronations, barons were specially designated from among the city councillors for the specific purpose of attending coronations. Originally, the barons were charged with bearing a ceremonial canopy over the sovereign during the procession to and from Westminster Abbey. The last time the barons performed such a task was at the coronation of George IV in 1821. The barons did not return for the coronations of William IV (who insisted on a simpler, cheaper ceremonial) and Victoria. At coronations since Victoria's, the barons have attended the ceremony, but they have not carried canopies.
