D. Pedro de Sousa Holstein, 1st Duke of Faial and Palmela (8 May 1781–12 October 1850) was one of the most important Portuguese diplomats and statesmen in the first half of the 19th century. He also served as the country's first modern Prime Minister (with the title of "President of the Council of Ministers"). Early life and career He was born in Turin, a scion of the Portuguese de Sousa family, Lords of Calhariz. The 'Holstein' element of his family name came from his paternal grandmother Princess Maria Anna Leopoldine of Schleswig-Holstein-Sonderburg-Beck, daughter of Frederick William I, Duke of Schleswig-Holstein-Sonderburg-Beck. His uncle had been governor of Portuguese India. He earned notoriety at an early age by telling Napoleon to his face at the conference in Bayonne in 1808 that the Portuguese would not ‘consent to become Spaniards’ as the French Emperor wanted. He was Portuguese plenipotentiary to the Congress of Vienna in 1814, where he attempted to press Portugal's claims to Olivenza, and to the Congress of Paris in 1815. After this he was briefly ambassador to London, but then was appointed secretary of state for foreign affairs in Brazil. After the Portuguese Revolution of 1820 he was commissioned by the revolutionary junta to inform the king, João VI, of what had taken place and to request his return to Portugal from Brazil. In 1823 he was made a Marquis and became foreign minister as well as head of the committee which D. João appointed to devise a new constitutional charter. The resulting document, to which the King was unable to agree, was so liberal that it drew down on Palmela the hatred of the reactionary forces in the country, especially the Queen and the Infant Dom Miguel, who in 1824 had him arrested. After he obtained his liberty he was made a minister of state and returned to London as ambassador. Liberal Wars When Dom Miguel seized the throne of Portugal in 1828 Palmela sided with the opposition in Oporto and was forced with many others to flee to England. An attempt to return to Oporto in June 1828, called the Belfastada, failed. Greville noted in his diary for 16 August 1828: ”Esterhazy told me to-night that Palmella entertains from twenty to thirty of his countrymen at dinner every day, of whom there are several hundred in London, of the best families, totally destitute.” Miguel condemned him to death
