Before she passed away, Queen Elizabeth II confirmed that she wanted Prince Charles' wife, Duchess Camilla, to become queen consort upon his ascension to the throne.

However, the duchess will not be Queen Camilla because there are five different "types" of queens in the United Kingdom.

1 – Queen (Queen Regnant)

The queen has the same rank as the king and is the person who has sovereign, military and political power.

2 – Queen Consort

A queen consort is the wife of a reigning king, in this case King Charles. So, I looked like Camilla.

3 – Queen Regent

The Queen Regent is the adult guardian of a child monarch who rules until the child comes of age.

4 – Queen "Dowager"

This is the widow of a king. She still has the title and importance of her previous position as Queen Consort, but is no longer actually Queen Consort due to a new monarch being on the throne. If Charles were to die before Camilla, she would become a queen dowager.

5 – Queen Mother

This is a bit complicated. A queen mother is essentially a queen who is the mother of the reigning monarch. Of course, Camilla is not the mother of the future monarch, Prince William, so she will not be known as the Queen Mother.
