Prince Consort
A "Prince Consort" is a title given to the husband of a reigning queen who does not hold the title of king. This role is often ceremonial, and the prince consort supports the queen in her duties while not having the same powers as a king. A famous example is Prince Philip, the Duke of Edinburgh, who was the husband of Queen Elizabeth II.
The position of prince consort can vary in importance and influence depending on the individual and the monarchy's traditions. While they may not have formal political power, they often play a significant role in public engagements and royal events, helping to represent the monarchy.
