PAKENHAM, Sir RICHARD (1797–1868), diplomatist, the fifth son of Admiral Sir Thomas Pakenham [q. v.], by his wife, Louisa, daughter of the Right Hon. John Staples, was born at Pakenham Hall, Castle Pollard, in Westmeath, on 19 May 1797. He completed his education at Trinity College, Dublin, and, apparently without waiting to take a degree, entered the foreign office on 15 Oct. 1817 as attaché to his uncle, the Earl of Clancarty, at the Hague. His next appointment was as secretary to the legation in Switzerland (26 Jan. 1824). Promoted on 29 Dec. 1826 to the same position in Mexico, he was made minister plenipotentiary to the United Mexican States on 12 March 1835. In this capacity he seems to have been popular and efficient. Perhaps the most troublesome of his negotiations was for the abolition of the slave trade: the Mexican government objected to the right of search, and the negotiations dragged on for four years, but he obtained the treaty in 1841. He was in Mexico during the war between that kingdom and France, and in February 1839 was despatched to Vera Cruz, with the object of trying to effect a reconciliation between the two countries. On 13 Dec. 1843, while on leave in England, he was made a privy councillor, and on 14 Dec. appointed envoy extraordinary and minister plenipotentiary to the United States of America. Here some thorny questions awaited him. One of his first duties was to take up that of the Oregon boundary. In this negotiation, though he did not carry the British points, he obtained the approval of his government. The attitude of Great Britain regarding Texas proved of greater difficulty. The relations between the two governments were not very cordial, and irritation was easily provoked on both sides. Pakenham left Washington on leave of absence in May 1847, and, after remaining in Europe for an unusually prolonged period, ultimately preferred to retire on pension rather than return to the States. He resumed his career on 28 April 1851 as envoy extraordinary and minister plenipotentiary at Lisbon. Here his diplomatic work was less arduous, and he rapidly ingratiated himself with the royal family of Portugal. In May 1855 he came to England on leave, and at his own request, on 28 June, retired on pension, but almost immediately (on 7 Aug.) was sent back to Lisbon on a special mission to congratulate Pedro V on attaining his majority. He returned to England once more in October 1855, was awarded a diplomatic pension of the second class, and retired to Coolure, Castle Pollard, where he died, unmarried, on 28 Oct. 1868.
