Britannia is the national personification of Britain as a helmeted female warrior holding a trident and shield. An image first used in classical antiquity, the Latin Britannia was the name variously applied to the British Isles, Great Britain, and the Roman province of Britain during the Roman Empire. Typically depicted reclining or seated with spear and shield since appearing thus on Roman coins of the 2nd century AD, the classical national allegory was revived in the early modern period. On coins of the pound sterling issued by Charles II of England, Scotland, and Ireland, Britannia appears with her shield bearing the Union Flag. To symbolise the Royal Navy's victories, Britannia's spear became the characteristic trident in 1797, and a helmet was added to the coinage in 1825.
