Edouard Dubufe. Cowley is shown amongst the diplomats attending the conference to end the
Crimean War. Wellesley entered the diplomatic service in 1824, receiving his first important appointment in 1845, when he became Minister Plenipotentiary to the Ottoman Empire. This was followed in June 1851 by his appointment as Envoy Extraordinary and Minister Plenipotentiary to the reinstated diet of the
German Confederation, a position which he only held for a short time, as he was chosen in 1852 to succeed
Lord Normanby as the British ambassador in Paris. Lord Cowley, as Wellesley had become on his father's death in 1847, held this important post for fifteen years, and the story of his diplomatic life in Paris cannot be separated from the general history of England and France. As Minister during the greater part of the reign of
Napoleon III, he conducted the delicate negotiations between the two countries during the time of those eastern complications which preceded and followed the
Crimean War, and also during the excitement and unrest produced by the attempt made in 1858 by
Felice Orsini to assassinate the emperor of the French; while his diplomatic skill was no less in evidence during the
war between France and
Austria and the subsequent course of events in
Italy. In 1857 he was created
Viscount Dangan, in the County of Meath, and
Earl Cowley. He was further honoured in 1866 when he was made a
Knight of the Garter. Having assisted
Richard Cobden to conclude the commercial treaty between Great Britain and France in 1860, he retired as ambassador in 1867. == Personal life==
