Portrait of Sir Charles Stewart

Sir Charles Stewart is an 1812 portrait by the English artist Thomas Lawrence of the Irish soldier and diplomat Charles Stewart. Stewart was a career soldier who had served in the Peninsular War as Adjutant General to Allied commander Lord Wellington. Stewart had returned home from Portugal when he posed for the portrait and was subsequently appointed British Ambassador to Prussia, launching a diplomatic career that saw him play a key role in forming the alliance that defeated Napoleon and attending the Congress of Vienna. He is shown in hussar uniform, a branch of light cavalry that became prominent during the Napoleonic Wars. He wears his Peninsular Medal earned for his service over the past four years.

Stewart became a friend and patron of Lawrence, securing him commissions from the Prince Regent from 1814 onwards. As the younger brother of the British Foreign Secretary Lord Castlereagh he was well-placed to secure sittings for Lawrence with European leaders, in some cases attending in order to advance British diplomatic objectives. In 1822 Stewart became the Marquess of Londonderry in succession to his brother whom Lawrence had painted several times including his 1809 Portrait of Lord Castlereagh.

The painting is now in the National Portrait Gallery having been purchased in 1992 with assistance from the Art Fund. Another version of the work is in Apsley House, thr Duke of Wellington's London residence.
