"God Save the Queen" is the national anthem of the United Kingdom and one of the few anthems that is both a de facto national anthem and a royal anthem. Originally published in 1745, its authorship remains uncertain, with some attributing its composition to John Bull, Thomas Arne, or even Henry Carey. The anthem has historically been adapted to suit the reigning monarch, changing to "God Save the King" when a king is on the throne. Over the years, its stirring melody and simple yet profound lyrics have inspired patriotism and unity, and it has been employed by various Commonwealth realms. The anthem remains a symbol of the British monarchy and national identity.
