John Quincy Adams (b. July 11, 1767, Braintree, Massachusetts-d. February 23, 1848, Washington, D.C.) was an American statesman who served as a diplomat, United States Senator, member of the House of Representatives, and the sixth President of the United States. He was a member of the Federalist, Democratic-Republican, National Republican, and later the Anti-Masonic and Whig parties. He was the son of President John Adams and Abigail Adams. As a diplomat, Adams played an important role in negotiating key treaties, most notably the Treaty of Ghent, which ended the War of 1812. As Secretary of State, he negotiated with Britain over the United States' northern border with Canada, negotiated with Spain the annexation of Florida, and drafted the Monroe Doctrine. Adams was elected president in a close and controversial four-way contest in 1824. As president he sought to modernize the American economy and promote education. After leaving office, he was elected as U.S. Representative from Massachusetts in 1830. Animated by his growing revulsion against slavery, Adams became a leading opponent of the Slave Power.
