Will Prince William Become Duke of Cornwall? How His Title Will Change Once Prince Charles Is King

Titles are a necessity in the royal family, and certain ones are valued more than others. According to the royal rulebook, dukedoms are the highest ranking titles in the monarchy (aside from king and queen, of course). And, some dukedoms — such as the Duke of Cornwall — are even more prominent.

Prince Charles is the current Duke of Cornwall but will drop his dukedom as soon as he ascends the throne. And, with the vacancy, Prince William could take his father’s place. Will Prince William become Duke of Cornwall? Find out, ahead.

Will Prince William become Duke of Cornwall?

When Prince Charles ascends the throne, a lot will change for Prince William — starting with his royal title. The Duke of Cornwall title is bestowed upon the eldest son (typically the heir) to the British throne, which means that Prince Charles could pass his old title onto his son.

However, Prince Charles becoming king doesn’t automatically make Prince William the Duke of Cornwall. The monarch must officially grant him with the honor in a ceremonious way.

Will Prince William become Prince of Wales?

If Prince William becomes the Duke of Cornwall, he likely will become the Prince of Wales, too. Despite its dukedom status — and belonging to the British heir — the Duke of Cornwall is a step below Prince of Wales, which also belongs to the monarch’s eldest child or heir.

Like Prince Charles, if Prince William receives both rankings, he will choose to go by the Prince of Wales over the Duke of Cornwall. However, he will still technically hold the honors.

Prince William’s royal title

When Princess William was born, Prince Charles was (and still is) the Prince of Wales. Because of that, Prince William’s royal title was His Royal Highness Prince William of Wales and remained that way until marriage.

Upon his royal wedding day, Queen Elizabeth II announced Prince William’s first royal dukedom, making him His Royal Highness Prince William, Duke of Cambridge and his wife, Her Royal Highness Catherine, Duchess of Cambridge. In addition, Prince William and Kate Middleton also became the Earl and Countess of Strathearn in Scotland and Baron and Lady Carrickfergus in Northern Ireland. But, these royal peerages likely won’t stick with them for long.

With Prince Charles closer than ever to the British throne, Prince William is close to becoming first in line. And, when that happens, his father could make him the Prince of Wales and Duke of Cornwall. As well as new royal titles for his duties in Scotland and Northern Ireland.

Will Prince William become king?

As the second in line to the British throne, Prince William will one day take over as the reigning monarch of the United Kingdom and Commonwealth countries. When that happens, he will drop all of his royal titles and be known as His Majesty the King until death or abdication.
