John Quincy Adams (July 11, 1767-February 23, 1848) was a diplomat, politician, and the sixth President of the United States (March 4, 1825-March 4, 1829). His party affiliations were Federalist, Democratic-Republican, National Republican, and later Anti-Masonic and Whig. Adams was the son of United States President John Adams, and Abigail Adams. He is most famous as a diplomat involved in many international negotiations, and for formulating the Monroe Doctrine. As president he proposed a grand program of modernization and educational advancement, but was unable to get it through Congress. Late in life, as a Congressman, he was a leading opponent of the Slave Power, arguing that if a civil war ever broke out the president could abolish slavery by using his war powers, a policy followed by Abraham Lincoln in the Emancipation Proclamation of 1863.
