The Earl Marshal of England is a hereditary Royal officeholder under the King or Queen of the United Kingdom.
In the Middle Ages, the Earl Marshal and the Lord High Constable were the officers of the King's horses and stables.
In conjunction with the Lord High Constable he had held a court, known as the Court of Chivalry, for the administration of justice in accordance with the law of arms, which was concerned with many subjects relating to military matters, such as ransom, booty and soldiers' wages, and including the misuse of armorial bearings.
