# Mountbatten-Windsor

Mountbatten-Windsor is the personal surname used by some of the male-line descendants of Queen Elizabeth II and Prince Philip, Duke of Edinburgh. Under a declaration made at a Privy Council meeting in 1960, the name Mountbatten-Windsor applies to male-line descendants of Queen Elizabeth II without royal styles and titles. Individuals with royal styles do not usually use a surname, but some descendants of the Queen with royal styles have used Mountbatten-Windsor when a surname was required.

## Privy Council Declaration

The full text of the 1960 Privy Council declaration is:
   My Lords
   Whereas on the 9th day of April 1952, I did declare in Council My Will and Pleasure that I and My children shall be styled and known as the House and Family of Windsor, and that My descendants, other than female descendants who marry and their descendants, shall bear the name of Windsor: And whereas I have given further consideration to the position of those of My descendants who will enjoy neither the style, title or attribute of Royal Highness, nor the titluar dignity of Prince and for whom therefore a surname will be necessary: And whereas I have concluded that the Declaration made by Me on the 9th day of April 1952, should be varied in its application to such persons:
   Now therefore I declare My Will and Pleasure that, while I and My Children shall continue to be styled and known as the House and Family of Windsor, My descendants other than descendants enjoying the style, title or attribute of Royal Highness and the titular dignity of Prince or Princess and female descendants who marry and their descendants shall bear the name of Mountbatten-Windsor.
The Privy Council declaration made it so that Elizabeth's descendants with princely titles and male-line descendants who bear princely titles keep the name Windsor, pursuant to a declaration she made in a previous Privy Council meeting at the beginning of her reign; female descendants who marry, their descendants, and any other descendants who do not hold princely titles use the surname Mountbatten-Windsor. While many of her descendants hold princely titles and styles, they usually use Mountbatten-Windsor instead of Windsor.

## Current use

The British monarchy asserts that the name Mountbatten-Windsor is used by members of the royal family who do not have a surname, when a surname is required. For example, Anne, Princess Royal, and Prince Andrew, Duke of York, children of Queen Elizabeth II, used the surname Mountbatten-Windsor in official marriage registry entries in 1973 and 1986 respectively. Likewise, William, Prince of Wales, used the name when filing a French lawsuit related to the topless pictures of his wife published by the French magazine Closer.
At the time of the 1960 declaration, palace officials claimed in private communications that it created a hidden surname that would emerge several generations later when some of Queen Elizabeth II's descendants were further removed from the throne. On the wedding of Prince Edward and Sophie Rhys-Jones in 1999, the Queen decided, with their agreement, that any of their future children should not be styled His or Her Royal Highness. Consequently, the birth of their daughter in 2003 marked the first emergence of the Mountbatten-Windsor surname. Their daughter was named Louise Alice Elizabeth Mary Mountbatten-Windsor, and she goes by the title of Lady Louise Mountbatten-Windsor, her father being the Duke of Edinburgh.
Mountbatten-Windsor differs from the official name of the British royal family, which remains the House of Windsor. In accordance with law and custom in the English-speaking world, the surname Mountbatten-Windsor belongs to all male-line descendants of Queen Elizabeth II and Prince Philip, and is used by them if and when a surname is needed. In contrast, male-line descendants of King George V, the first monarch of the House of Windsor, use Windsor as their surname if and when a surname is needed, as for example Lady Davina Windsor and Lady Marina Windsor, respectively descended from George V's sons Prince Henry, Duke of Gloucester and Prince George, Duke of Kent. (George V's other sons have no male-line descendants: King George VI had only daughters while King Edward VIII had no issue and Prince John was unmarried.) After the House of Saxe-Coburg and Gotha was renamed Windsor, other descendants of Queen Victoria and Prince Albert could also use the name Windsor, as for example, Alastair Arthur Windsor, 2nd Duke of Connaught and Strathearn, grandson of their son Prince Arthur, Duke of Connaught and Strathearn. None do so today, however, because the only male line (apart from the descendants of King George V) is through Charles Edward, Duke of Saxe-Coburg and Gotha, whose descendants use the surname Saxe-Coburg and Gotha (English) or von Sachsen-Coburg und Gotha (German).
