Édouard Drouyn de Lhuys (pronounced [edwaːʁ dʁuɛ̃ də‿lɥis]; 19 November 1805 – 1 March 1881) was a French diplomat.
Drouyn de Lhuys served as Minister of Foreign Affairs from 1848 to 1849 in the first government of Odilon Barrot.
He resigned his post in 1855, during the Crimean War, when the peace preliminaries he had agreed to in consultation with the British and Austrians at Vienna were rejected by Napoleon III.
Drouyn de Lhuys returned to power 7 years later, in 1862, when foreign minister Édouard Thouvenel resigned over differences with Napoleon on Italian affairs.
"[1] In the aftermath of that war, which was disastrous to French interests in Europe, Drouyn resigned and withdrew into private life.
