United States Ambassador to the United Kingdom in the context of "Edward Everett"

Presidential elections were held in the United States on November 4, 1856. Democratic nominee James Buchanan defeated Republican nominee John C. Frémont and Know Nothing/Whig nominee Millard Fillmore. The main issue was the expansion of slavery as facilitated by the Kansas–Nebraska Act of 1854. Buchanan defeated President Franklin Pierce at the 1856 Democratic National Convention for the nomination. Pierce had become widely unpopular in the North because of his support for the pro-slavery faction in the ongoing civil war in territorial Kansas, and Buchanan, a former Secretary of State, had avoided the divisive debates over the Kansas–Nebraska Act by being in Europe as the Ambassador to the United Kingdom.

Slavery was the main issue, and with it the question of the survival of the United States as it then existed. The Democrats were seen as the pro-slavery party. While the new Republican party was hostile to slavery, they limited their efforts to the politically more manageable question of the extension of slavery into federal territories (and its removal from the District of Columbia). The nativist Know Nothings (known formally as the American Party) competed with the Republicans to replace the moribund Whig Party as the primary opposition to the Democrats. They emphasized opposition to Catholic immigrants.

Rose Elizabeth Fitzgerald Kennedy (July 22, 1890 – January 22, 1995) was an American philanthropist, socialite, and matriarch of the Kennedy family. She was deeply embedded in the "lace curtain" Irish-American community in Boston. Her father, John F. Fitzgerald, served in the Massachusetts State Senate (1892–1894), in the U.S. House of Representatives (1895–1901, 1919), and as Mayor of Boston (1906–1908, 1910–1914). Her husband, Joseph P. Kennedy Sr., chaired the U.S. Securities and Exchange Commission (1934–1935) and the U.S. Maritime Commission (1937–1938), and served as United States Ambassador to the United Kingdom (1938–1940). Their nine children included United States President John F. Kennedy, U.S. Senator Robert F. Kennedy of New York, U.S. Senator Ted Kennedy of Massachusetts, Special Olympics founder Eunice Kennedy Shriver, and U.S. Ambassador to Ireland Jean Kennedy Smith. In 1951, Rose Kennedy was ennobled by Pope Pius XII, becoming the sixth American woman to be granted the rank of Papal countess.
