A queen consort is the wife of a reigning king. Unlike a queen regnant, who rules in her own right, a queen consort does not hold sovereign power. Her role is primarily supportive, often involving ceremonial duties and representing the monarchy at public events. Queen consorts may also engage in charitable work and social causes, helping to enhance the royal family's image. Historical examples include Queen Elizabeth, the Queen Mother and Queen Victoria, who both played significant roles in their respective royal families while supporting their husbands' reigns.
