A Royal Standard of the 1816-1837 pattern. The standard is made of wool bunting, it is hand-sewn and painted. Rope ties are attached to the linen hoist.

The arms of England (in the first and fourth quarters) are quartered with Scotland and Ireland. The Hanoverian arms are placed in an escutcheon 'overall' in the centre. These are: gules, two lions passant guardant in pale or (for Brunswick); or, semé of hearts gules, a lion rampant azure (for Luneburg); gules, a horse courant argent (for Westphalia). Over all an inescutcheon gules charged with the golden crown of Charlemagne (the augmentation or badge of the Arch Treasurer of the Holy Roman Empire).

In 1816 the electorate of Hanover was elevated to the dignity of a kingdom at the Congress of Vienna and the electoral bonnet on the Hanoverian shield of arms was replaced by the royal crown seen on this standard.

The Royal Standard was one of three flags (the Royal Standard at the main, Union at the mizzen, and anchor flag at the fore) used to indicate that the sovereign was on board a particular warship. The same three flags were flown by naval ships during their launch.
