A New American Diplomacy: The Monroe Doctrine

– Message of President James Monroe at the commencement of the first session of the 18th Congress (The Monroe Doctrine) December 2, 1823 (in the collection of the National Archives).


“We shall either be a united people, more strongly bound by a common danger, or we shall become a prey to foreign influence.”

– Abigail Adams to John Adams, April 5, 1797.


Independence brought the United States into a world dominated by European empires, each with interests in the western hemisphere. The United States desired to balance trade with these empires while steering “clear of European contentions,” as Thomas Paine cautioned in Common Sense. European contentions, President James Monroe learned, often boiled over into the Americas. During his second term, James Monroe feared Spain might reassert its control over newly independent Latin American countries. British Foreign Minister George Canning feared this as well, and suggested that the United States sign a joint declaration with Great Britain protecting the western hemisphere from Spanish intervention. At the advice of Secretary of State John Quincy Adams, however, Monroe declined. Instead, he pursued similar objectives, without the alliance, in his seventh annual address to Congress. Part of this speech, known as the Monroe Doctrine, was the culmination of decades of diplomatic experience and political ideology. In short, it separated the two hemispheres by preserving Latin American independence and asserting non-intervention by European powers.

Though the Monroe Doctrine allowed newly independent Latin American republics to pursue their own destinies without interference from European nations, it also paved the way for American imperialism. By committing the Untied States to protect its own interests, the Monroe Doctrine advanced the United States’ authority over Latin America. Presidents throughout the late nineteenth and early twentieth century invoked the Monroe Doctrine, and in some instances expanded its scope and meaning, to pursue expansionist goals and solidify their power in the western hemisphere. James K. Polk, for example, was the first to draw upon the Doctrine’s language during the Mexican War. Theodore Roosevelt famously amended the Doctrine with the Roosevelt Corollary, which justified military intervention in Latin America. John F. Kennedy also cited the Doctrine to oppose Soviet pressure during the Cuban Missile Crisis.

These sources show the formation of America’s new foreign policy. In a letter dated October 17, Monroe asked Thomas Jefferson for advice on how best to pursue George Canning’s proposal for an alliance. Jefferson’s response a week later encouraged Monroe to agree to it, considering Monroe’s dilemma the greatest since their pursuit for independence. The excerpt from Monroe’s congressional address, the Monroe Doctrine, is Monroe’s, and the United States’, answer to this “momentous” diplomatic question presented before the country.
