The Princess of Hanover is a title held by the female descendants of the House of Hanover, a royal family that originated in Germany. This title is often associated with the British royal family due to the historical connection between the House of Hanover and the British monarchy, particularly during the reign of King George I in the early 18th century. Currently, the title is held by Princess Caroline of Monaco, who is the daughter of Prince Rainier III of Monaco and Grace Kelly. She became the Princess of Hanover through her marriage to Prince Ernst August of Hanover, linking her to the historical lineage of the Hanoverian dynasty.
