John Quincy Adams was one of the most significant statesmen-intellectuals of the Early American Republic. Highly intelligent, well-traveled, and massively educated, Adams was a Christian nationalist who believed that the American Republic was destined to be a shining example of democracy and liberty to the rest of the world. He was profoundly influenced by his parents, John and Abigail, and embraced his father’s political philosophy which was rooted in a written constitution and a strong three branch government constrained by checks and balances. Adams served as US minister to several European nations before becoming secretary of state in 1817 and then the sixth president of the United States in 1824. He began life as a Federalist but strongly supported the foreign policies of the Jefferson and Madison administrations. The three pillars of his foreign policy were neutrality toward Europe, continental expansion, and hemispheric hegemony. Adams chaired the US delegation that negotiated the Treaty of Ghent in 1814 and was the driving force behind the Convention of 1818 and the Transcontinental Treaty of 1819. Adams partnered with President James Monroe in formulating the Monroe Doctrine in 1823, which canonized the principles of the two hemispheres including European non-colonization in the Western hemisphere and US non-interference in European affairs.
Domestically, Adams was a relentless exponent of the American System in which the federal government would fund a system of internal improvements—turnpikes, canals, ports—that would create a national market and bind the various regions together by means of a national economy. In this, he was disappointed in part because he had the misfortune to be president when Jacksonian democracy was taking hold in America and distrust of the federal power was growing. Defeated for re-election by Andrew Jackson in 1828, Adams briefly retired from public life but then accepted election to the House of Representatives in 1830 where he served until his death in 1846. In the House, he proved to be an avid opponent of the further extension of slavery into the territories, and ironically, of further continental expansion. He became convinced that a civil war was inevitable but held abolitionists at arm’s length because of their rejection of the Constitution as a means to achieve racial justice in America. Adams died with a deep sense of failure, believing that his earlier career as an expansionist had produced not an empire of liberty but an empire of slavery.
