“The Queen has today been pleased to confer a Dukedom on Prince Henry of Wales. His titles will be Duke of Sussex, Earl of Dumbarton and Baron Kilkeel,” the palace said. “Prince Harry thus becomes His Royal Highness The Duke of Sussex, and Ms. Meghan Markle on marriage will become Her Royal Highness The Duchess of Sussex.”

While Meghan is the first person to hold that title, Harry is the second to be known as the "Duke of Sussex." The first was reportedly an anti-slavery advocate, allocated the prestigious title in 1801, according to CNN. The tradition of giving titles dates back to feudal times -- but now, it's used for members of the royal family.

The queen can choose up to five titles for a man or a woman. And though Princess Meghan sounds ideal, Dukedom is "highest" of them all.
