# British princess

The use of the title of Princess of the United Kingdom of Great Britain and Northern Ireland is entirely at the will of the sovereign, and is now expressed in letters patent. Individuals holding the title of princess will usually also be granted the style of Her Royal Highness (HRH). The current letters patent were issued in 1917 during World War I, with one extension in 2012.
Between 1714 and 1917, pursuant to the then custom, daughters of the monarch and daughters of male-line descendants of a monarch were accorded the rank of a British princess. King George V issued letters patent on 30 November 1917 (issue 30428, Dec. 14, 1917, p. 2.), predefining who held the title, style and rank of a British Princess to restrict the automatic assignment of the title "princess" and the use of the style "Royal Highness" to the following persons:
* the legitimate daughters of a British Sovereign
* the legitimate male line granddaughters of a British sovereign.
On 31 December 2012, Queen Elizabeth II issued letters patent enabling daughters of the eldest son of the Prince of Wales to hold the title princess and style Royal Highness, as opposed to only the eldest son (the 1917 patent having extended "prince" to his eldest living son).
The wife of a British prince whose marriage has been approved by the British Sovereign is automatically accorded the status of the prince (princess) and the feminine form of her husband's titles.

## Princesses of the blood royal and princesses by marriage

Under the current practice, princesses of the blood royal are the legitimate daughters and the legitimate male line granddaughters of a British sovereign. They are dynasts, that is potential successors to the throne. For these individuals, the title "Princess of the United Kingdom of Great Britain and Northern Ireland" and the style "Her Royal Highness" is an entitlement for life. The title Princess and the style Royal Highness is prefixed to the Christian name, before another title of honour. From 1714 until 1917, the male-line great-granddaughters of the Sovereign were titled "Princess of Great Britain and Ireland" with the style "Highness". Since 1917, the male-line great-granddaughters of the Sovereign have held "the style and title enjoyed by the children of dukes". For example, the daughters of Prince Richard, Duke of Gloucester, a male line grandson of George V, are styled Lady Davina Windsor and Lady Rose Gilman.
The legal wife of a British prince is also entitled to the status and rank of a British princess. If their husband is not the holder of his own substantive title, then the wife of a British prince has the right to be styled as Princess followed by their husband's first given name. However, if their husband is the holder of either a Dukedom or an Earldom then this takes precedence. For example, upon her marriage to Prince Michael of Kent in 1978, Baroness Marie-Christine von Reibnitz assumed the title and style of "Her Royal Highness Princess Michael of Kent". Similarly, upon her marriage to then Prince Richard of Gloucester, the former Birgitte van Deurs assumed the title and style of "Her Royal Highness Princess Richard of Gloucester". Upon marriage, the wife of the prince of Wales becomes "Her Royal Highness The Princess of Wales". Upon marriage, the wife of a royal duke (or earl) becomes "Her Royal Highness The Duchess (or Countess) of X". When Prince Richard of Gloucester succeeded to his father's dukedom in 1974, his wife became "Her Royal Highness The Duchess of Gloucester". Since 1714, only four princesses were at marriage known in their title by their husband's name, since all the others took the duchess form of the royal duke's title. The four are Princess George of Cumberland, Princess Arthur of Connaught, Princess Richard of Gloucester and Princess Michael of Kent.
Princesses by marriage are entitled to the style "Royal Highness" by virtue of marriage, and retain the style if widowed. However, Elizabeth II issued letters patent dated 21 August 1996 stating that any woman divorced from a prince of the United Kingdom would no longer be entitled to the style "Royal Highness". This has so far applied to Diana, Princess of Wales, and Sarah, Duchess of York. The title of HRH is not intrinsically linked to the title of Princess. Diana was restyled as "Diana, Princess of Wales" following her divorce as a courtesy of the late Queen Elizabeth II having been officially styled as The Princess of Wales during marriage. If Diana had ever remarried then she would have lost the right to the style and title completely.
Since the passage of the Royal Marriages Act 1772, there were a few instances in the reign of King George III in which princes of the blood contracted marriages without consent of the king. This meant they were not legally married, denying the woman the lawful style "Her Royal Highness", as well as any title in the peerage. For example, Prince George, Duke of Cambridge, a male-line grandson of King George III, 'married' Sarah Louisa Fairbrother: the marriage was in contravention of the Royal Marriages Act, and therefore legally invalid. Accordingly, the duke's wife was never titled the Duchess of Cambridge or accorded the style "Her Royal Highness". Instead, she was known as "Mrs FitzGeorge". An exception to the rule was created for King Edward VIII following his 1936 abdication. King George VI issued letters patent dated 27 May 1937 that entitled The Duke of Windsor, as Edward was now entitled, "to hold and enjoy for himself only the title, style or attribute of Royal Highness so however that his wife and descendants if any shall not hold the said title, style or attribute".
There is also the case when a princess of the blood royal marries a British prince. She also becomes a princess by marriage and will be addressed in the same way. An example of this situation was the late Princess Alexandra, Duchess of Fife, when she married her cousin Prince Arthur of Connaught and became "Princess Arthur of Connaught, Duchess of Fife".
Typically a princess by marriage should not be called princess followed by her first name. Diana, Princess of Wales, was consistently referred to as "Princess Diana" by fans and the media, but this usage of the title is technically erroneous, as she was not the child of a monarch nor the child of a son of a monarch. However, this tradition was broken once in the past century with Elizabeth II's aunt, Princess Alice, Duchess of Gloucester, being referred to—with permission from the sovereign—in official sources as such following the death of her husband.

## History

The use of the titles prince and princess and the styles of Highness and Royal Highness for members of the Royal Family is of fairly recent usage in the British Isles. Before 1714, there was no settled practice regarding the use of the titles prince and princess other than the heir apparent and his wife. From 1301 onward, the eldest sons of the Kings of England (and later Great Britain and the United Kingdom) have generally been created Prince of Wales and Earl of Chester. Their wives were titled Princess of Wales.
The title Princess Royal came into being in 1642 when Queen Henrietta Maria, the French-born wife of King Charles I, wished to imitate the way the eldest daughter of the French King was styled Madame Royale. However, there was no settled practice on the use of the title princess for the Sovereign's younger daughters or male-line granddaughters. For example, as late as the time of King Charles II, the daughters of his brother James, Duke of York, both of whom became Queens regnant, were called simply "The Lady Mary" and "The Lady Anne". The future Queen Anne was styled princess in her marriage treaty to Prince George of Denmark and then styled "Princess Anne of Denmark" once married. However, in exile at Saint-Germain-en-Laye, the deposed James II & VII gave the title of Princess Royal to his last daughter, Louisa Maria (1692–1712).
After the accession of George Louis of Hanover as King George I, the children, grandchildren, and male line great-grandchildren of the British Sovereign were automatically titled "Prince or Princess of Great Britain and Ireland" and styled "Royal Highness" (in the case of children and grandchildren) or "Highness" (in the case of male line great-grandchildren). Queen Victoria confirmed this practice in letters patent dated 30 January 1864 (the first Act of the Prerogative dealing with the princely title in general terms).
On 31 December 2012, Elizabeth II issued letters patent enabling all children of the eldest son of the Prince of Wales to enjoy the princely title and style of Royal Highness, as opposed to only the eldest son.

## Styling of princesses
### Princesses of the blood royal

* Daughter of a Sovereign: HRH The Princess N (e.g. HRH The Princess Margaret).
** The style HRH The Princess Royal is customarily (but not automatically) granted by the Sovereign, when vacant, to the Sovereign's eldest daughter.
* Daughter of a son of a Sovereign: HRH Princess N of X, where X is the territorial designation of their father's senior peerage; e.g. HRH Princess Alexandra of Kent, HRH Princess Charlotte of Wales, HRH Princess Lilibet of Sussex.
** Prior to Princess Charlotte, a daughter of the Prince of Wales: HRH Princess N
** Prior to 1917, a daughter of a son of a son of a Sovereign: HH Princess N of X
* From 31 December 2012, daughter of the eldest son of the Prince of Wales: HRH Princess N of X (e.g. HRH Princess Charlotte of Cambridge, until 2022).
When a princess marries, she still takes on her husband's title. If the title is higher than (or equal to) the one she possesses, she will normally be styled using the female equivalent. If her husband has a lower title or style, her style as a princess remains in use, although it may then be combined with her style by marriage, e.g. HRH The Princess Louise, Duchess of Argyll or HRH Princess Alice, Countess of Athlone – if that princess had a territorial designation, she may cease its use. It has become customary, however, for a princess who has been granted the title of HRH The Princess Royal to not combine it with her style by marriage: Princess Anne remains HRH The Princess Royal rather than HRH The Princess Royal, Lady Laurence.

### Princesses by marriage

A princess by marriage is addressed as "Princess Husband's name"; this is akin to a woman being referred to as "Mrs. John Smith". The only recent time this has broken tradition is with the sovereign's express consent. Namely, with Queen Elizabeth II's aunts Princess Alice, Duchess of Gloucester, and Princess Marina, Duchess of Kent. The former was not a princess by birth, while the latter was born a princess of Greece and Denmark. Both women asked the Queen to use their given names after their husbands' deaths.
* Wife of a prince who has a peerage: HRH The Duchess/Countess of X, or, prior to 1917, possibly HH (e.g. HRH The Duchess of Edinburgh and HRH The Duchess of Sussex)
** Since 1996, divorced wife of a prince who held a peerage: N, Duchess/Countess of X. (e.g. Diana, Princess of Wales, and Sarah, Duchess of York)
* Wife of a son of a Sovereign, who has no peerage: HRH The Princess Husband.
* Wife of another prince who has no peerage: HRH Princess Husband of X. (X usually taken from father's Dukedom; e.g. HRH Princess Michael of Kent)
* Prior to 1917, the wife of a prince in the third generation, who has no peerage: HH Princess Husband of X.

### Exceptions

* There were only two historical princesses who would have been exceptions to the 1917 rule, but they died long before that. The sisters Sophia Matilda and Caroline Augusta Maria born in 1773 and 1774 were male line great-granddaughters of George II. All of the other exceptions were still alive in 1917 and were no longer permitted to use the style of HRH and Princess.
There have been several exceptions in recent history to these rules, but all have come by order of the Sovereign, mostly through letters patent.
* In November 1905, King Edward VII allowed the two daughters of Louise, Princess Royal to use a princely title and the style of Highness. They were not entitled to the style of Royal Highness. The 1917 letters patent which stripped great-grandchildren of a British sovereign of the style of Highness with a princely title was complicated as it did not technically overrule Edward VII's letters patent, as the former practice was mostly an unspoken courtesy as opposed to a written rule. The elder sister, Princess Alexandra, Duchess of Fife, was already married by that time, to Prince Arthur of Connaught: he was a male-line grandson of Victoria, and so entitled to use the style of Royal Highness. Alexandra was therefore styled Her Royal Highness Princess Arthur of Connaught, Duchess of Fife from her 1913 marriage for the rest of her life, and the 1917 letters patent did not change this. Her younger sister, Princess Maud, on the other hand, was unmarried in 1917. Until her 1923 marriage, she continued to use the title of "Princess" granted to her in 1905. Upon her marriage to Charles, Lord Carnegie, however, she chose to be known as Lady Maud Carnegie (or, from 1941, The Countess of Southesk), dropping her princely title.
* Charles III had the style and title His Royal Highness Prince Charles of Edinburgh from birth in 1948, even though he was a female-line grandchild of the Sovereign, being born to the future Elizabeth II, then Princess Elizabeth, Duchess of Edinburgh, during the reign of Elizabeth's father, King George VI, who had no sons. George VI issued letters patent on 22 October 1948, granting the style to Elizabeth's children. Under the same exception, Anne, Princess Royal was styled Her Royal Highness Princess Anne of Edinburgh from her birth in 1950 until her mother's accession in 1952.
* In 1961, when her son married, the Duchess of Kent asked Elizabeth II to extend the use of a princely title to precede her first name, in order to avoid confusion with her daughter-in-law, Katharine Worsley, the new Duchess of Kent. As she was born a princess of Greece and Denmark, this was not incredibly notable, although traditionally she would have been styled as Her Royal Highness The Dowager Duchess of Kent. After this she was styled as Her Royal Highness Princess Marina, Duchess of Kent.
* In 1974, the Duchess of Gloucester asked Elizabeth II for the same title as her sister-in-law, then Princess Marina, Duchess of Kent, with a princely title preceding her first name. Unlike Princess Marina, Alice had never been a princess in her own right, thus this allowance was far more unusual. Instead of being referred to as Her Royal Highness The Dowager Duchess of Gloucester, as is customary, she became Her Royal Highness Princess Alice, Duchess of Gloucester.
* In 2003, upon the request of Elizabeth II's youngest son, Edward, his children would be styled as the children of an earl, though still retaining their royal titles. The children would be able to decide if they would want to use the title once they turned eighteen. As male-line grandchildren of a British monarch, Lady Louise Mountbatten-Windsor and the James, Earl of Wessex, would traditionally enjoy a princely title and style.
* In December 2012, Elizabeth II issued letters patent that stated that all children born to the eldest child of the Prince of Wales (then her son Charles), would enjoy a princely title and style, and not just the eldest son. Although in effect since 2012, it was not used in practice until the birth of Princess Charlotte in 2015.
