HRH Henry Frederick (1745–1790), 1st Duke of Cumberland and Strathearn

HRH Henry Frederick, 1st Duke of Cumberland and Strathearn from 1786 by John Hoppner depicts a younger brother of King George III. Royal portraits by Hoppner reflected his position as a painter favored by the Prince of Wales, who often commissioned portraits as part of his rivalry with his father's preferred artist, Thomas Lawrence. Characteristic of the artist's mature approach, the work displays fluent, confident brushwork in the tradition of Reynolds, with a warm atmospheric palette and a gift for flattering likenesses that retained individual character.

The royal portrait combines the formality expected of a royal sitter with Hoppner's distinctive painterly fluidity, creating an atmospheric portrait of the prince.
