The Lord High Constable of England is the seventh of the Great Officers of State, ranking beneath the Lord Great Chamberlain and above the Earl Marshal. His office is now called out of abeyance for coronations alone (and theoretically for trials by combat). The Lord High Constable was originally the commander of the royal armies and the Master of the Horse. He was also, in conjunction with the Earl Marshal, president of the Court of Chivalry or Court of Honour. In feudal times, martial law was administered in the court of the Lord High Constable. The constableship was granted as a grand serjeanty with the Earldom of Hereford by the Empress Maud to Milo de Gloucester, and was carried by his heiress to the Bohuns, Earls of Hereford and Essex. Through a coheiress of the Bohuns it descended to the Staffords, Dukes of Buckingham; and on the attainder of Edward Stafford, 3rd Duke of Buckingham, in the reign of King Henry VIII it became merged in the crown. The Lacys and Verduns were hereditary constables of Ireland from the 12th to the 14th century; and the Hays, Earls of Erroll, have been hereditary Lord High Constables of Scotland from early in the 14th century.
