A soldier and statesman, Wellington's early victories were in India and the Spanish Peninsula. In 1815, he was hailed as the man who finally achieved the peace of nations when he led the defeat of Napoleon at the Battle of Waterloo. He later entered Parliament, where he was a bastion of ultra-Tory values against the forces of liberal change. He was Prime Minister between 1828 and 1830 and again in 1834. The subject, 'Wellington musing on the Field of Waterloo' was conceived by the painter Haydon as a companion to his 'Napoleon musing at St Helena'. In a portrait full of pathos, the ageing hero, wearing civilian clothes, is shown looking out over the scene of his greatest triumph at Waterloo, almost fifteen years after the event. The Duke's dislike of sitting for his portrait, at least latterly, was well-known.
