Roosevelt Corollary, foreign policy declaration by U.S. Pres. Theodore Roosevelt in 1904–05 stating that, in cases of flagrant and chronic wrongdoing by a Latin American country, the United States could intervene in that country’s internal affairs. Roosevelt’s assertion of hemispheric police power was soon characterized as the Roosevelt Corollary to the Monroe Doctrine, though, in reality, it was a significant extension of that doctrine rather than an interpretation of it. Nevertheless, it was designed to preclude violation of the Monroe Doctrine by European countries seeking redress of grievances against unruly or mismanaged Latin American states.
A longtime foundation of U.S. foreign policy articulated by Pres. James Monroe in 1823, the Monroe Doctrine asserted that the United States would not interfere in the wars between, or the internal affairs of, European powers and, moreover, that it recognized and would not interfere with existing European colonies and dependencies in the Western Hemisphere. However, the doctrine further asserted that the Western Hemisphere was no longer open to colonization and that any attempt by a European power to oppress or control any country in the Western Hemisphere would be viewed as a hostile act against the United States. Beginning in the 1870s, interpretation of the Monroe Doctrine became increasingly broad, and, as the United States emerged as a world power, the doctrine came to define a recognized sphere of influence.
Several times during Theodore Roosevelt’s first years in the presidency, European powers threatened intervention in Latin America, ostensibly to collect debts owed them by weak governments in the region. In 1902 the United Kingdom, Italy, and Germany established a blockade of the coast of Venezuela in an effort to compel that country to make good on such debts. Roosevelt responded by making a show of naval force and urging U.S. mediation. Some two years later the United States again intervened in the region when European powers threatened forcibly to collect debts defaulted on by the Dominican Republic. In an attempt to prevent his country from falling into bankruptcy, the Dominican Republic’s dictatorial ruler, Ulises Heureaux, had entered into corrupt and complex refinancing schemes with European nations, skimming millions of dollars for himself. Under his regime, the Dominican Republic found itself bearing a crippling burden of debts to French and British creditors. Following Heureaux’s assassination in 1899, the Dominican Republic was too weak financially to repay these creditors, and, in response, the French and British governments positioned warships in the Caribbean.
These French and British warships constituted a European presence that threatened to displace the significant economic and political interests of the United States in the region. Thus, Roosevelt reacted quickly, establishing an American receivership of the Dominican customs in order to collect the revenues to meet the country’s debt payments. The American “economic adviser” whom Roosevelt installed effectively became the country’s financial director.
In his annual message to Congress of 1904, Roosevelt announced the new Latin American policy that soon became known as the Roosevelt Corollary to the Monroe Doctrine: because that doctrine forbade European use of force in the New World, the United States would itself take whatever action was necessary to guarantee that Latin American states gave no cause for such European intervention. In his message to Congress the next year, Roosevelt detailed how the role of the United States as the international policeman for the Western Hemisphere would be carried out:
It must be understood that under no circumstances will the United States use the Monroe Doctrine as a cloak for territorial aggression. We desire peace with all the world, but perhaps most of all with the other peoples of the American continent. There are, of course, limits to the wrongs which any self-respecting nation can endure. It is always possible that wrong actions toward this nation or toward citizens of this nation in some state unable to keep order among its own people, unable to secure justice from outsiders, and unwilling to do justice to those outsiders who treat it well, may result in our having to take action to protect our rights; but such action will not be taken with a view to territorial aggression, and it will be taken at all only with extreme reluctance and when it has become evident that every other resource has been exhausted.
The Roosevelt Corollary became closely associated with—and, for observers, synonymous with—Roosevelt’s Big Stick policy. Derived from his fondness for a West African proverb—“Speak softly and carry a big stick; you will go far”—that policy called for the assertion of U.S. domination when such dominance was considered a moral imperative.
