The Royal Family new titles have been given since the passing of Queen Elizabeth II.
There will be significant changes to the royal family’s roles following the passing of Queen Elizabeth II on September 8.
Most significantly, Prince Charles, the eldest son of the Queen, effectively ascended to the throne right away.
Prime Minister Liz Truss declared, “Today the Crown passes — as it is has done for more than a thousand years — to our new monarch, our new head of state: His Majesty King Charles III.”
The change in the line of succession has also resulted in other royal family members receiving new titles. Following are those members whose titles have been officially changed.

Royal Family new titles- King Charles III
Age: 73
Prince Charles will henceforth be referred to as King Charles III following the passing of Queen Elizabeth II.
Royal Family new titles- Queen Consort Camilla
Age: 75
Camilla will now be addressed as Queen Consort because she is the King’s wife, an honour Queen Elizabeth explicitly desired in February.
On September 9, King Charles III spoke about Camilla in his address, “In recognition of her own loyal public service since our marriage seventeen years ago, she becomes my Queen Consort.”
Royal Family new titles- William, Prince of Wales
Age: 40

King Charles III said in his speech on September 9 that William will succeed to the rank of Prince of Wales, which Charles had previously held.
Ever since his April 2011 wedding to Kate Middleton, Prince William has been referred to as the Duke of Cambridge.
The Duke of Cornwall is usually held by the eldest son of the current British monarch, with his wife receiving the Duchess title. As a result of Queen Elizabeth’s passing, the official @KensingtonRoyal Twitter and Instagram accounts usernames were altered to “Duke and Duchess of Cornwall and Cambridge.”
William has become the Prince of Wales and has inherited his father’s Duchy of Cornwall. His primary responsibilities as the successor to the throne are to assist the King in carrying out his official duties.
Royal Family new titles- Catherine, Princess of Wales
Age: 40

Just like her husband on her wedding day in April 2011, Kate Middleton received the title of Duchess of Cambridge. She most recently received the title of Duchess of Cornwall after Queen Elizabeth passed away.
Kate will take the title of Princess of Wales, originally held by William’s late mother Princess Diana, King Charles III said in his speech. Although Kate’s children’s official documents refer to her as the “Princess of the United Kingdom,” it is the first time she has adopted the princess title formally.
Prince George of Wales
Age: 9

His Royal Highness Prince George of Cambridge is the first kid of William and Catherine; however, given that Charles is King, it has been speculated that George may one day be referred to as Prince George of Cornwall and Cambridge. Now, his another and most noble title is Prince George of Wales.
Behind his father, Prince George is next in line for the crown.
Princess Charlotte of Wales
Age: 7

Her Royal Highness Princess Charlotte of Wales is third in succession to the throne, following her father, William, and older brother, George. Her Royal Highness Princess Charlotte of Cambridge is the name of William and Kate’s second child given in official documents.
Prince Louis of Wales
Age: 4

His Royal Highness Prince Louis of Cambridge, is the name given to William and Kate’s third child at the time of his birth. Louis Arthur Charles is fourth in line to the throne.
