The British royal family is one of the oldest royal families in the world. Since 1066, the throne has been passed down from generation to generation by people with the same blood. Because Britain allows women who are related to the royal family to inherit the throne, this has caused the phenomenon that the British royal family has the same blood but different dynasty names.

The relationship between the British monarch and his close relatives is known from his name. Although there is no strict law or formal definition of royal family members, different lists will have different members, but people with HM (Your Majesty) or HRH (Royal Highland) titles are generally regarded as royal family members.

What is the surname of the British royal family? Windsor, of course, now. But is it really that simple? Before 19 17, members of the British royal family had no surnames, only the names of their dynasties or families. The tradition that a king or queen only writes his own name when signing a document has been maintained in Britain until now.

19 17, George v not only renamed his ruling dynasty and royal residence as "Windsor", but also made it a family name. The Queen ascended the throne in 1952, and determined "Windsor" as the royal family name. After George V, all his male and unmarried female descendants were named Windsor.

However, by 1960, the Queen and Prince Philip hoped that their direct descendants would be different from other members of the royal family. So the Privy Council announced that the title of Prince/Princess and the married female MP would be abolished.

All direct descendants of the Queen should take "mountbatten Windsor" as their surname. After this announcement, all the queen's children will call each other "Mountbatten Windsor" when they need to show their surnames.

Generally speaking, members of the royal family who are awarded the title of prince or princess do not need a surname, but if necessary (such as getting married), their surname will be "mountbatten Windsor".
