Who Wrote the Monroe Doctrine?

The Monroe Doctrine was one of the most influential policies in United States history. The question of who wrote the Monroe Doctrine can help to explain the significance of the policy and how it shaped the United States.

President James Monroe declared the new American foreign policy on December 2nd, 1823 during his seventh annual message to Congress. This message is now referred to as the “State of the Union” and typically delivered by the President in person to Congress, though at the time Thomas Jefferson set a precedent for it to be written and delivered to Congress.

In his message Monroe warned European powers against colonization in the Americas. While the United States would respect existing colonies in the Americas, any European attempt to expand would be viewed as “dangerous to our peace and safety.”

While the Monroe Doctrine surely had noble elements to it concerning the protection of burgeoning Central and South American republics, the primary reason for the policy was the self-interest of the United States. The doctrine was a warning to any nation that could challenge the eventual supremacy of the US in the western hemisphere.

Interestingly enough, Monroe’s message was not referred to as a doctrine for several decades after the declaration. Use of the Monroe doctrine varied by President, though it was largely inconsequential throughout most of the nineteenth century.

The United States was simply too weak to enforce the policy and extend its influence throughout the region.

As US power and influence expanded in the late nineteenth/early twentieth centuries the doctrine morphed to justify intervention in the Americas whenever it was in the United States’ best interests.

Though the Monroe Doctrine was utilized differently throughout the history of the United States, its impact on US foreign policy cannot be understated.

Who Wrote the Monroe Doctrine?

The Monroe Doctrine was primarily written by Monroe’s Secretary of State, John Quincy Adams. Quincy Adams would go on to succeed Monroe as President in the important election of 1824.

Adams’ influence on the policy is well known given his deep suspicions of European intentions in the Americas.

At the time many Central and South American republics were in their infancy, having just fought and won independence primarily from Spain. The United States was concerned that these new republics would not survive if European nations attempted to reestablish the old colonies.

Great Britain was the only European nation that was constitutionally governed at the time,1 and it feared the implications of further European involvement in the Americas would shift the balance of power. Great Britain much preferred the new republics remained independent, and thus Britain could establish favorable trading terms.

With this in mind, Britain proposed an alliance with the United States to establish a joint declaration opposing European colonization in the Americas. For good measure, Britain also proposed that the United States and Britain adhere to a self-denial clause2 that would limit both nations from claiming new land themselves.

The proposal was enticing to Monroe. He reached out to former presidents Thomas Jefferson and James Madison for their advice. Both agreed that an alliance with Britain would certainly protect the United States from the colonial ambitions of other European nations.

John Quincy Adams, however, vehemently disagreed. Britain could not be trusted in this matter, as it would be the chief commercial competitor in the region with the United States. In addition, Adams particularly disliked the self-denial clause that could prevent the United States from pursuing some of its own expansionist ideals in the future.

Adams’ recommendation won out, and he heavily influenced the Monroe Doctrine.

What did the Monroe Doctrine Say?

Buried within Monroe’s seventh annual message to Congress in 1823, the Monroe Doctrine delivered three main points.

First: the Americas were not open for colonization from European nations. 

“The American continents, by the free and independent condition which they have assumed and maintain, are henceforth not to be considered as subjects for future colonization by any European powers.”3

Second: the United States declared the monarchies of Europe to be too incompatible with the republics of the Americas. These differing political arrangements would jeopardize the peace and safety of the American nations.

“The political system of the allied powers is essentially different in this respect from that of America… We owe it, therefore, to candor and to the amicable relations existing between the United States and those powers to declare that we should consider any attempt on their part to extend their system to any portion of this hemisphere as dangerous to our peace and safety.”3

Third: the United States would maintain its policy of remaining uninvolved in European affairs. This remained consistent with the example set by George Washington in his farewell address.

“Our policy in regard to Europe, which was adopted at an early stage of the wars which have so long agitated that quarter of the globe, nevertheless remains the same, which is, not to interfere in the internal concerns of any of its powers.”3

These three points delivered the primary message of the Monroe Doctrine: Europeans are to stay out of American affairs.

Despite the powerful language, European nations generally disregarded the message. The United States was too weak at the time and lacked sufficient naval and military power to enforce the lofty declaration.

The Significance of the Monroe Doctrine

The Monroe Doctrine would prove to be extremely significant in regards to the foreign policy of the United States. Some Presidents utilized the doctrine more often than others, leading to an inconsistent approach in the decades after implementation.

Despite popular belief, the Monroe Doctrine was not the first time the United States had discussed preventing colonialism in the Americas. Alexander Hamilton in the Federalist Papers discussed at length finding an American balance of power opposing that of Europe, with the United States’ strength leading the western hemisphere.4

In general, the Monroe Doctrine was rarely enforced throughout the nineteenth century. The United States was too preoccupied with its own expansionist ambitions and the Civil War as well as too weak militarily to properly enforce the policy.

While the US enacted the doctrine following the French invasion of Mexico in the 1860s, it was powerless to then force the French out of Mexico. But in other instances the US ignored European intervention, such as when the British reasserted their possession of the Falkland Islands. 

The real significance of the Monroe Doctrine came in the years before and after the Spanish-American war. It was around this period that the United States emerged on the world stage and exhibited imperialistic tendencies of its own.

The original intentions of the doctrine were to protect American interests and ideals against the perceived wave of European monarchy and despotism.5

Beginning with the Venezuelan Crisis of 1895, the United States’ interpretations of the Monroe Doctrine began to change. 

Corollary to the Monroe Doctrine

In 1895 the first major change, or corollary, to the Monroe Doctrine was declared. Today it is referred to as the “Olney Corollary.”

In it, then-Secretary of State Richard Olney broadened the interpretation of the Monroe Doctrine to claim that the United States had the authority to mediate border disputes throughout the western hemisphere.

Although the British-Venezuelan border dispute was eventually settled by European courts, it was the first time the United States took a more outward-looking stance in regards to foreign policy.

Following this event, the United States took a more active role in the affairs of the western hemisphere. In 1904, the Roosevelt Corollary to the Monroe Doctrine was implemented.

In it, President Theodore Roosevelt declared the United States had the ability to intervene in the affairs of any American nation that failed to honor its obligations. Essentially, it authorized the US to “police” the region and intervene in other nations’ affairs as it saw fit.

The ships of the Great White Fleet further entrenched the idea that America was ready to use its newfound naval power to enforce its own imperial ambitions. 

While Central and South American nations had always been wary of US intentions in regards to the Monroe Doctrine, the Roosevelt Corollary confirmed their suspicions.

Many historians agree that later US interpretations of the Monroe Doctrine proved to distance it from its American neighbors instead of bringing them closer together.6 Whereas the doctrine may have had good intentions, in reality the fear of United States domination weighed heavily on the other American nations.

Given the varying interpretations of the Monroe Doctrine over the years, its legacy is disputed, though it is unquestionably one of the most impactful foreign policies in United States history.
