　　John Quincy Adams (July 11, 1767 – February 23, 1848) was the sixth President of the United States from March 4, 1825 to March 4, 1829. He was also an American diplomat and served in both the Senate and House of Representatives. He was a member of the Federalist, Democratic-Republican, National Republican, and later Anti-Masonic and Whig parties.
　　
　　Adams was the son of the second President John Adams and his wife Abigail Adams, the name "Quincy" having come from Abigail's maternal grandfather, Colonel John Quincy, after whom Quincy, Massachusetts is also named.[pn 1] He was a diplomat, involved in many international negotiations, and helped formulate the Monroe Doctrine as Secretary of State. As president he proposed a program of modernization and educational advancement, but was stymied by Congress. Adams lost his 1828 bid for re-election to Andrew Jackson.
　　
　　Adams was elected a U.S. Representative from Massachusetts after leaving office, the only president ever to do so, serving for the last 17 years of his life. In the House he became a leading opponent of the Slave Power and argued that if a civil war ever broke out the president could abolish slavery by using his war powers, which Abraham Lincoln partially did during the American Civil War in the 1863 Emancipation Proclamation.
