Following the Queen's passing, aged 96, on Thursday 8th September, many speculated about her eldest son Prince Charles' new royal title.
Buckingham Palace announced the news of the Queen's death on Thursday afternoon, revealing: "The Queen died peacefully at Balmoral this afternoon.
"The King and The Queen Consort will remain at Balmoral this evening and will return to London tomorrow."
Hours later, it was confirmed that Prince Charles, the new monarch, will now be known as King Charles III. His wife Camilla, formerly known as the Duchess of Cornwall, will now be recognised as the Queen Consort.
Here's everything you need to know about several members of the Royal Family's new titles:
King Charles III
As a British monarch, Charles – who is aged 73 – was entitled to choose any name upon his accession to the throne. For example, King Charles' grandfather's was baptised as Albert Frederick Arthur George but, on becoming king, he became George VI.
Meanwhile, the late Queen's great-great-grandmother, Queen Victoria, changed her name, after having been baptised as Alexandrina Victoria.
Camilla, Queen Consort
Following her marriage to the then Prince Charles in 2005, Buckingham Palace announced that Camilla would take on the title Princess Consort once her husband ascended the throne.
Queen Elizabeth later expressed her "sincere wish" for her daughter-in-law to be known as the Queen Consort.
Ahead of her 70th anniversary of her accession to the throne, the late royal wrote: "When, in the fullness of time, my son Charles becomes King, I know you will give him and his wife Camilla the same support that you have given me; and it is my sincere wish that, when that time comes, Camilla will be known as Queen Consort as she continues her own loyal service."
The title of 'Consort' is traditionally given to the wife or husband of a reigning monarch. Meanwhile, 'Queen' is given to female rulers.
Prince William and Kate Middleton
The Duke and Duchess of Cambridge have updated their social media handles following the Queen's death.
In addition to their Cambridge titles, which they adopted in 2011 following their marriage, the couple notably added Cornwall to their bio – a title which was previously held by the former Prince Charles and Camilla.
The young couple's bio now reads: "The official account of The Duke and Duchess of Cornwall and Cambridge and the Royal Foundation, based at Kensington Palace." Their handle remains @KensingtonRoyal.
It's believed King Charles will soon make his oldest son William the Prince of Wales, the title traditionally handed to the heir to the throne.
It's unknown how or if the title change will affect the Cambridge couple's three children: Prince George, Princess Charlotte and Prince Louis.
Prince Harry and Meghan Markle
In 2018 the couple adopted the titles of the Duke and Duchess of Sussex when they wed in Windsor, and have since stepped back as senior working members of the royal family. As a result of the latter, they gave up the right of being referred to as His and Her Royal Highness.
However, following King Charles' ascension to the throne, it's unlikely the Sussexes' titles will change. But, it might mean their children – Archie and Lili – might be given the titles of Prince and Princess, respectively. The children weren't born with royal titles as a result of a letters patent issued by King George V in 1917, which stated that only the children of the sovereign, the children of the sons of the sovereign, and the eldest living son of the eldest son of the Prince of Wales were able to be princes and princesses.
