Rule, Britannia

"Rule, Britannia!" is a British patriotic song, originating from the poem "Rule, Britannia" by James Thomson and set to music by Thomas Arne in 1740. It is strongly associated with the Royal Navy, but also used by the British Army.

This British national air was originally included in Alfred, a masque about Alfred the Great co-written by Thomson and David Mallet and first performed at Cliveden, country home of Frederick, Prince of Wales (the eldest son of George II and father of the future George III, as well as the great-grandfather of Queen Victoria), on 1 August 1740, to commemorate the accession of George II and the third birthday of the Princess Augusta.

Frederick, a German prince who arrived in England as an adult and was on very bad terms with his father, was making considerable efforts to ingratiate himself and build a following among his subjects-to-be (which came to naught, as he predeceased his father and never became king). A masque linking the prince with both the medieval hero-king Alfred the Great's victories over the Vikings and with the current building of British sea power – exemplified by the recent successful capture of Porto Bello from the Spanish by Admiral Vernon on 21 November 1739, avenging in the eyes of the British public Admiral Hosier's disastrous Blockade of Porto Bello of 1726–27 – went well with his political plans and aspirations.
