It has been used since the 13th century and signifies the heir apparent to the throne. The title is often accompanied by various ceremonial duties and responsibilities, including representing the monarchy at official events. The current holder of the title is Prince William, who became the Prince of Wales following the accession of his father, King Charles III, in 2022. The title is associated with the historic region of Wales, and the investiture ceremony is a significant event in Welsh culture.
