However the Queen made it clear she wanted Camilla to be known as Queen Consort before she died on September 8, 2022.
In an official statement shared to mark the beginning of her Platinum Jubilee celebrations in February 2022, the Queen revealed her plans for when Prince Charles is King.
"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 Queen wrote.
The statement made headlines around the world as news outlets, royal reporters and the public reacted to "Queen Camilla", a title many had suggested the Queen herself would never allow.
Now that Her Majesty has died, Camilla will take up the title in an official capacity as Charles becomes King.
In his first official statement as King Charles, the 72-year-old wrote: "We mourn profoundly the passing of a cherished Sovereign and a much-loved Mother.
“I know her loss will be a 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."
