The Lord High Steward is the first of the Great Officers of State in England, nominally ranking above the Lord Chancellor.

The office has generally remained vacant since 1421, and is now an ad hoc office that is primarily ceremonial and is filled only for a coronation.

At coronations of the British monarch, the Lord High Steward bears St Edward's Crown. The Lord High Steward has the sole legal power to preside over impeachment trials of peers (which last happened in 1806). The trial of peers by their peers (a law which applied for felonies) was abolished in 1948. In general, but not invariably, the Lord Chancellor was deputised (to act as Lord High Steward) in the felony trials. There was a "Court of the Lord High Steward" which served this purpose when Parliament was not in session.^[1]

Initially the position was largely an honorary one. It grew in importance until its holder became one of the most powerful men of the kingdom. From the late 12th century, the office was considered to be bound with the Earldom of Leicester. When the House of Lancaster ascended the throne in 1399, Henry IV made his second son, Thomas of Lancaster, Duke of Clarence, Lord High Steward. He held the post until his death in 1421.^{[citation needed]}

The equivalent offices in Scotland and Ireland respectively are the Great Steward of Scotland (always held by the heir to the throne, known in Scotland as the Duke of Rothesay) and the Lord High Steward of Ireland (held by the Earls of Shrewsbury, who are also Earls of Waterford in the Peerage of Ireland).^{[citation needed]}
