Queen Elizabeth II has passed away at the age of 96.
The heartbreaking news was announced by Buckingham Palace on Thursday, September 8.
Following a day where the world waiting anxiously for an update regarding the beloved monarch's health, the Palace announced shortly after 6PM: "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."
Her eldest son has now ascended the throne and will be known officially as King Charles III.
With King Charles III as the nation's new monarch, several formalities and title changes have taken place with immediate effect.
Two of which include the new king's grandchildren - the daughter and son of Prince Harry and Meghan Markle.
Due to rules put in place by George V in 1917, Archie and Lilibet are now technically Prince Archie and Princess Lilibet, due to the fact that they are the grandchildren of a sovereign and therefore have the automatic right to the titles.
They will also be known as His and Her Royal Highness (HRH), respectively.
Per the Guardian, these titles can be withdrawn if King Charles III issues a Letters Patent amending Archie’s right to be a prince and Lili’s right to be a princess.
More than 100 years ago, King George V declared: "The grandchildren of the sons of any such Sovereign in the direct male line (save only the eldest living son of the eldest son of the Prince of Wales) shall have and enjoy in all occasions the style and title enjoyed by the children of Dukes of these Our Realms."
Other title changes that have immediately changed include King Charles III's wife, who will now be known as the Queen Consort ('consort' being the term used for the spouse of the monarch).
Despite being the new heir apparent, Prince William will not become the Prince of Wales. However, he and wife Catherine will adopt the title of the Duke and Duchess of Cornwall, respectively.
Following the loss of his mother, the new king released the following statement: "The death of my beloved Mother, Her Majesty The Queen, is a moment of the greatest sadness for me and all members of my family.
"We mourn profoundly the passing of a cherished sovereign and a much-loved mother.
"I know her loss will be deeply felt throughout the country, the Realms and the Commonwealth and by countless people around the world.
"During this period of mourning and change, my family and I will be comforted and sustained by our knowledge of the respect and deep affection in which the Queen was so widely held."
