Peerages in the United Kingdom form a legal system comprising both hereditary and lifetime titles, composed of various ranks, and within the framework of the Constitution of the United Kingdom form a constituent part of the legislative process and the British honours system. The British monarch is considered the fount of honour and is notionally the only person who can grant peerages, though there are many conventions about how this power is used, especially at the request of the British government. The term peerage can be used both collectively to refer to the entire body of titled nobility, and individually to refer to a specific title. British peerage title holders are termed peers of the Realm.
Duke is a male title either of a monarch ruling over a duchy, or of a member of royalty, or nobility. As rulers, dukes are ranked below emperors, kings, grand princes, grand dukes, and sovereign princes. As royalty or nobility, they are ranked below princes and grand dukes. The title comes from French duc, itself from the Latin dux, 'leader', a term used in republican Rome to refer to a military commander without an official rank, and later coming to mean the leading military commander of a province. In most countries, the word duchess is the female equivalent.
Duke of Cornwall is a title in the Peerage of England, traditionally held by the eldest son of the reigning British monarch, previously the English monarch. The Duchy of Cornwall was the first duchy created in England and was established in a royal charter in 1337 by King Edward III. As of 2022, Prince William became Duke of Cornwall following the accession to the throne of his father, King Charles III; William's wife, Catherine, became Duchess of Cornwall.
Duke of Gloucester is a British royal title, often conferred on one of the sons of the reigning monarch. The first four creations were in the Peerage of England and the last in the Peerage of the United Kingdom; the current creation carries with it the subsidiary titles of Earl of Ulster and Baron Culloden.
The order of precedence in the United Kingdom is the sequential hierarchy for Peers of the Realm, officers of state, senior members of the clergy, holders of the various Orders of Chivalry, and is mostly determined, but not limited to, birth order, place in the line of succession, or distance from the reigning monarch. The order of precedence can also be applied to other persons in the three legal jurisdictions within the United Kingdom:
Duke of Buckingham, referring to Buckingham, is an extinct title that has been created several times in the peerages of England, Great Britain, and the United Kingdom. There were creations of double dukedoms of Buckingham and Normanby and of Buckingham and Chandos. The last holder of the dukedom died in 1889.
Duke of Clarence was a substantive title created three times in the Peerage of England. The title Duke of Clarence and St Andrews has also been created in the Peerage of Great Britain, and Duke of Clarence and Avondale and Earl of Clarence in the Peerage of the United Kingdom. The titles have traditionally been awarded to junior members of the English and British royal family, and all are now extinct.
Duke of Kent is a title that has been created several times in the peerages of Great Britain and the United Kingdom, most recently as a royal dukedom for the fourth son of King George V. Since 1942, the title has been held by Prince Edward, a first cousin of Queen Elizabeth II.
Duke of Albany is a peerage title that has occasionally been bestowed on younger sons in the Scottish and later the British royal family, particularly in the Houses of Stuart and Hanover.
Duke of Somerset, from the county of Somerset, is a title that has been created five times in the peerage of England. It is particularly associated with two families: the Beauforts, who held the title from the creation of 1448, and the Seymours, from the creation of 1547, in whose name the title is still held. The present dukedom is unique, in that the first holder of the title created it for himself in his capacity of Lord Protector of the Kingdom of England, using a power granted in the will of his nephew King Edward VI.
Duke of Fife is a title in the Peerage of the United Kingdom that has been created twice, in both cases for the Earl of Fife. In 1889, Lord Fife married Princess Louise, the eldest daughter of Albert Edward, Prince of Wales and a granddaughter of Queen Victoria.
The following is the order of precedence in England and Wales as of October 2024. Separate orders exist for men and women.
Duke of Richmond is a title in the Peerage of England that has been created four times in British history. It has been held by members of the royal Tudor and Stuart families.
Duke of Leeds was a title in the Peerage of England. It was created in 1694 for the prominent statesman Thomas Osborne, 1st Marquess of Carmarthen, who had been one of the Immortal Seven in the Revolution of 1688. He had already succeeded as 2nd Baronet, of Kiveton (1647) and been created Viscount Osborne, of Dunblane (1673), Baron Osborne, of Kiveton in the County of York and Viscount Latimer, of Danby in the County of York, Earl of Danby, in the County of York (1674), and Marquess of Carmarthen (1689). All these titles were in the Peerage of England, except for the viscountcy of Osborne, which was in the Peerage of Scotland. He resigned the latter title in favour of his son in 1673. The Earldom of Danby was a revival of the title held by his great-uncle, Henry Danvers, 1st Earl of Danby.
The hereditary peers form part of the peerage in the United Kingdom. As of August 2023, there are 805 hereditary peers: 30 dukes, 34 marquesses, 189 earls, 110 viscounts, and 442 barons.
Prince of the United Kingdom of Great Britain and Northern Ireland is a royal title normally granted to sons and grandsons of reigning and past British monarchs, together with consorts of female monarchs. The title is granted by the reigning monarch, who is the fount of all honours, through the issuing of letters patent as an expression of the royal will.
Duke of Clarence and St Andrews was a title created in 1789 in the Peerage of Great Britain for Prince William Henry. He was also created Earl of Munster in the Peerage of Ireland at the same time.
In the British peerage, a royal duke is a member of the British royal family, entitled to the titular dignity of prince and the style of His Royal Highness, who holds a dukedom. Dukedoms are the highest titles in the British roll of peerage, and the holders of these particular dukedoms are princes of the blood royal. The holders of the dukedoms are royal, not the titles themselves. They are titles created and bestowed on legitimate sons and male-line grandsons of the British monarch, usually upon reaching their majority or marriage. The titles can be inherited but cease to be called "royal" once they pass beyond the grandsons of a monarch. As with any peerage, once the title becomes extinct, it may subsequently be recreated by the reigning monarch at any time.
Duke, in the United Kingdom, is the highest-ranking hereditary title in all five peerages of the British Isles. A duke thus outranks all other holders of titles of nobility.
