Meghan Markle joined the British Royal Family in 2018. It all became official when she tied the knot with Prince Harry after almost two years of dating.

Hours before the royal event started, Queen Elizabeth "conferred" a Dukedom to her grandson. The Palace announced that he would become the Duke of Sussex, Earl of Dumbarton and Baron Kilkeel, according to Harper's Bazaar. As for the former Suits actress, she would receive the counterpart titles, which are the Duchess of Sussex, Countess of Dumbarton and Baroness Kilkeel.

The publication said that Meghan Markle is the first woman to hold the peerage. It seemingly came as a surprise to many as King George III first created the title Duke of Sussex in 1801.

The Daily Express reported that there was a huge "royal scandal" that surrounded the title. Prince Augustus Frederick received the title from his father upon its creation. However, he had an annulment seven years prior to receiving the honor.

Reports recalled that the royal-born Prince married Lady Augusta Murray in 1793. The relationship ended a year after, adding that it became "incredibly scandalous." Accordingly, she was not eligible to hold the title of Duchess of Sussex.

Prince Augustus married his second wife, Lady Cecilia Gore in 1831. The same publication noted, though, that King George III did not approve of the marriage, as well.

Therefore, no one considered her as a "legitimate wife" of the first Duke of Sussex. The title became extinct following the death of Prince Augustus in 1843.

Almost two hundred centuries later, Queen Elizabeth decided to give the royal peerage to Prince Harry and Meghan Markle. The same publication pointed out that the British Monarch is the only eligible person to decide which royal titles to give and to whom.

These days, the Sussex couple has seemingly continued to use their royal titles, excluding their HRH styles. This comes after they exited the British Monarchy earlier in March.

Some sources stated that Meghan Markle and Prince Harry no longer want to use their Sussex titles. But, amid the talks of Megxit, the British Monarch retained their royal peerages.

Queen Elizabeth, also, retained their HRH titles. However, the couple is e not allowed to use them in their current capacity as they are no longer working royals.

Aside from their HRH styles, they are not, also, allowed to use the word royal. This is why they had to relinquish their social media accounts, as well as their royal foundation.
