The British National Anthem, known as "God Save the King" (or "God Save the Queen" when a queen is reigning), is the national anthem of the United Kingdom. It is often played at official events, ceremonies, and sports competitions. The anthem expresses loyalty to the monarch and is recognized for its distinctive melody. The origins of the anthem date back to the 18th century, with the first known publication in 1744. It has since become a symbol of national pride and unity. The anthem is also used by other Commonwealth realms, reflecting the historical ties to the British monarchy.
