The title Princess of Wales may best be associated with Princess Diana, but one day, the title will likely pass to Kate Middleton. Probably one of the most popular royal in the U.K, the Duchess of Cambridge has gained his place as a well-loved candidate to hold a royal title Camilla Parker-Bowles rejected. Kate Middleton’s current title is Catherine, Her Royal Highness Princess William, Duchess of Cambridge, Countess of Strathearn, Baroness Carrickfergus but she received a shorter but sweet nickname as “The Children’s Princess” because she is quite invested working with Children Hospices.
Let's start with the beginning. Diana became Princess of Wales when she married Charles in 1981 and after her death, no one held the title until Charles married again in 2005 to Camilla Parker-Bowles.In due respect to Diana, Camilla does not use the title and instead goes as 'The Duchess of Cornwall'. (There would surely be a public outcry if Camilla used Diana's title.) Once Prince Charles inherits the throne from his mother Queen Elizabeth, everyone's title may change.
The Duke of Cambridge, Prince William may or may not become Duke of Cornwall or Prince of Wales since titles are not assumed by the heir to the throne and instead, the new monarch chooses if the title passes along. Charles must grant William “the personal honor”: the title of Prince of Wales. If everything goes as expected his wife, Catherine will become Duchess of Cornwall.
Charles, for example, did not become the Prince of Wales until his mother granted him the title in 1958 when he was 9 years old. And he wasn't "crowned" Prince of Wales until July 1, 1969, at the age of 20. As an extra, Prince Charles is the longest-serving Prince of Wales in history, Because he was already the Prince of Wales when he married Diana, she became the Princess of Wales automatically by marriage.
If Prince William becomes the Prince of Wales, it's likely they no longer be called Duke and Duchess of Cambridge, but rather the Prince and Princess of Wales because of the higher rank. But what will happen when, after Charles, his son William inherits the throne? “Kate will be Queen Consort without any question,” royal commentator Richard Fitzwilliams said. “We've only quite recently had the clarification again that Camilla will be Princess Consort, not Queen Consort. Princess Consort historically is something that doesn't exist, it's been invented.” It is said that Camilla has no desire to be queen and instead will settle as Princess consort.
