When discussing the British royal family, the question of what name binds Prince Harry and Prince William together arises frequently. While they are known by their first names and military titles, the legal and historical identifier they share is their surname. This surname connects them to a lineage stretching back centuries and defines their place within the intricate structure of the monarchy.
The Historical Context of Royal Surnames
For much of British history, kings and queens did not use surnames in the modern sense. They were known simply by the name of the royal house to which they belonged, such as the Tudors or the Stuarts. This tradition changed significantly in the early 20th century as the concept of nationality and documentation evolved. The house name provided the functional equivalent of a surname, but it was not a family name in the way we understand them today.
The Origin of the Mountbatten-Windsor Name
The specific surname used by Prince Harry and Prince William is a direct result of a combination of two distinct royal lineages. The name originates from the union of the House of Windsor, established by King George V, and the House of Mountbatten, an anglicized version of the German Battenberg name adopted due to anti-German sentiment during World War I. The current monarch, King Charles III, is a descendant of both lines, creating the compound surname.
Prince Philip's Influence
Prince Philip, Duke of Edinburgh, played the pivotal role in merging these two houses. As a member of the House of Mountbatten, he insisted that his descendants carry on his name. However, he respected the established royal house of Windsor. The solution was to combine the two, resulting in the surname Mountbatten-Windsor, which serves as the official last name for all descendants of Queen Elizabeth II and Prince Philip who do not hold the title of Prince or Princess with a territorial designation.
When the Surname is Used
While Mountbatten-Windsor is their legal surname, its usage is specific and context-dependent. In everyday life, Prince William is known as Prince William, and Prince Harry is known as Prince Harry. The surname is primarily employed for official and administrative purposes, such as signing legal documents, military service records, or census forms. Without a specific territorial title to differentiate them, this is the name that would officially identify them.
Exceptions and Special Cases
It is important to note that not all members of the royal family carry the Mountbatten-Windsor name. Princes and Princesses who hold a specific dukedom, earldom, or other peerage title often use that title as their surname in formal settings. For instance, Prince William holds the title Duke of Cambridge, making "Cambridge" a surname he uses. Similarly, Prince Harry was known as Captain Harry Wales during his military career, using "Wales" derived from his father's title, Prince of Wales.
