Flags of Charles III

King Charles III has and has had a variety of flags to represent him as a prince, duke, and, eventually, head of state of three of his 15 realms; in the latter case, the heraldic flags are the nation's coat of arms in banner form. The flags are usually used on any building, ship, car, or aircraft where Charles is present.

Prince Charles had six personal standards prior to his accession as King. As Prince of Wales, his primary standard consisted of four quarters consisting of three lions passant for England, a lion rampant for Scotland, and a Gaelic harp for Ireland, superimposed with the arms of Llywelyn the Great.

Upon the death of his mother, Prince Charles became King Charles III and, therefore, inherited two versions of the royal standard of the United Kingdom: one for use inside of Scotland and one for use outside of Scotland. The latter is used to represent the King not only in the United Kingdom, aside from Scotland, but, also overseas when he makes state visits. It is the British royal arms in banner form undifferentiated.
