Prince Harry became the Duke of Sussex on Saturday, Buckingham Palace announced , and Meghan Markle will officially adopt the royal title of Duchess of Sussex once they tie the knot later in the day.

Queen Elizabeth II followed tradition by bestowing the title upon the newlyweds on their wedding day. Harry was also given Scottish and Northern Irish titles, becoming the Earl of Dumbarton and Baron Kilkeel.

Since Markle doesnt come from royal lineage, she isnt eligible for a princess title, though she will also technically be known as Her Royal Highness Princess Henry of Wales.

The title of Duke of Sussex was last conferred on a member of the royal family in 1801, to Prince Augustus Frederick , one of King George IIIs sons. He had two children with his first wife, but the king didnt approve the marriage, meaning the dukes son couldnt inherit his title.
