The Royal Family members, Camilla, Prince William, and Kate Middleton, have been honored with historic royal titles.
Prince William is now the Great Master of the Order of the Bath.
Catherine, the Princess of Wales, has been appointed as a Companion of Honour, which recognizes achievements in arts, medicine, sciences, and public service.
Queen Camilla has become the Grand Master of the Order of the British Empire, a title previously held by her husband, King Charles, and his father, Prince Philip, and grandfather, George VI.
These appointments, traditionally announced on St. George's Day, come at a time when both King Charles and Catherine have been undergoing cancer treatment.
The Queen, at the age of 76, continues to carry out official duties in the absence of the King.
She has been appointed as the new head of the Most Excellent Order of the British Empire (MBE), which honors civilian and military recipients.
The Queen's eldest son, Prince Charles, recommended Catherine, who is recovering from health issues, to be the first royal to be appointed as a Companion of Honour in the order's history.
Catherine joins a prestigious group of individuals recognized for their contributions to public life, including Sir David Attenborough, Ian McEwan, and Sir Elton John.
Prince William will assume the role of Great Master of the Order of the Bath, a position previously held by his father when he was the Prince of Wales.
The Order of the Bath, established in the 18th century, recognizes exceptional military or civilian service.
Simultaneously, the Duchess of Gloucester, at the age of 77, has been appointed as a member of the oldest and most prestigious order of chivalry, the Order of the Garter, which dates back to the 14th century.
