John Quincy Adams

John Quincy Adams served as James Monroe’s secretary of state from 1817 to 1825 and as president from 1825 to 1829. His diplomatic career began at fourteen, when he accompanied Francis Dana to Russia as a private secretary. After studying at Harvard and entering the law, he served as American minister to the Netherlands and Prussia, with later assignments in Russia and Britain. He also helped negotiate the Treaty of Ghent, which ended the War of 1812. His presidency was followed by a long career in the House of Representatives. 1

As secretary of state, Adams negotiated the 1819 treaty with Spanish minister Luis de Onís that transferred Florida to the United States and defined a boundary reaching the Pacific. He used Spain’s difficulty controlling Florida to press for a settlement. The agreement recognized Spanish sovereignty over Texas and committed the United States to settle qualifying American claims against Spain, up to a total of $5 million. Ratification followed in 1821. He also played a central part in shaping the statement of American policy announced by Monroe in 1823. 4, 2, 3

As president, Adams sought wider commercial ties through treaties with European and Latin American governments. His proposal to send delegates to the Panama Congress encountered opposition in the Senate, including southern concern about the antislavery policies of the new republics. Delays prevented effective American participation. Negotiations also failed to secure satisfactory access to the British West Indies, limiting his administration’s commercial program. 5

Adams advocated roads, canals, scientific institutions, and other federal support for national development. These proposals faced constitutional objections and an opposition increasingly organized around Andrew Jackson. The disputed election of 1824 and Adams’s appointment of Henry Clay as secretary of state had left opponents alleging a “corrupt bargain.” Adams lost the 1828 election, then returned to public office in Congress, where he challenged restrictions on antislavery petitions and became a prominent opponent of slavery’s political power. He remained in the House until his death in 1848. 6, 4
