They became king and queen consort following the Queen’s death on September 8.
Queen Elizabeth II’s death brought about a number of title changes – for example, William and Kate are now known as the Prince and Princess of Wales.
But as Camilla, the wife of the monarch, is called Queen Consort, many people are wondering why the late Prince Philip, husband of Queen Elizabeth II, was never called King Consort.

Why was Prince Philip not called King Consort?
Prince Philip, who died on April 9, 2021, was known as the Duke of Edinburgh and Prince Consort.
The Queen, who was crowned in 1953, made Philip a prince of the United Kingdom in 1957.
Philip was actually born a prince – his official title was Prince Philip of Greece and Denmark – but he relinquished his Greek and Danish titles to marry the Queen.
However, despite being married to the Queen, he was never known as king.
