Rule, Britannia! was written in 1740 for the masque Alfred, with music by Thomas Arne and words by James Thomson. Originally performed to celebrate British identity, it grew into one of the country's best known patriotic songs and became closely linked with the Royal Navy and the idea of Britain as a maritime power. It is a regular highlight of the Last Night of the Proms and is heard at sporting and ceremonial events. Online, the short chorus has been reused in memes celebrating or mocking British pride.
