The "Knights of the United Kingdom" refers to individuals who have been honored with knighthood, a prestigious title awarded for various forms of service to the nation. This honor is part of the British Honours System, which recognizes contributions in fields such as arts, science, and public service. Knights are typically appointed by the monarch and receive the title "Sir" for men and "Dame" for women. Knighthood has a long history in the United Kingdom, dating back to the medieval period when knights were warriors serving a lord. Today, the title is largely ceremonial, symbolizing respect and achievement rather than military service. Notable knights include figures like Sir Winston Churchill and Dame Judi Dench.
