What It Is
The Monroe Doctrine was articulated in President James Monroe's December 1823 annual message to Congress (drafted largely by Secretary of State John Quincy Adams). The doctrine had three core principles:
- The Americas were closed to further European colonization.
- The US would not interfere in existing European colonies or internal European affairs.
- European interference in independent American states would be viewed as hostile to US interests.
The doctrine was articulated at a moment when newly independent Latin American states faced potential European recolonization attempts. It positioned the US as the security guarantor of Western Hemisphere independence — a position the US could not actually enforce in 1823 but increasingly could enforce as US power grew.
Historical Development
The doctrine had limited practical effect for decades until US power grew sufficiently to enforce it. Early applications were rhetorical more than operational.
The Roosevelt Corollary (1904) by President Theodore Roosevelt expanded the doctrine to assert US right to police 'chronic wrongdoing' in the hemisphere. The Corollary was used to justify multiple early-20th-century US interventions in Cuba, the Dominican Republic, Haiti, Nicaragua, and elsewhere. The Corollary transformed the Monroe Doctrine from a defensive against European into an active justification for US intervention.
The Good Neighbor Policy (Franklin Roosevelt, 1933) moved away from intervention temporarily, but the underlying Monroe Doctrine remained available for revival.
Cold War Applications
During the Cold War, the Monroe Doctrine was invoked to justify US opposition to Soviet influence in the hemisphere:
- The 1962 invoked Monroe Doctrine principles.
- The 1965 Dominican Republic intervention under the .
- Support for anti-communist Latin American governments through the 1970s and 1980s.
- The 's Latin American applications (Nicaragua Contras, El Salvador) continued Monroe Doctrine logic.
The Kerry 'Over' Statement
The Kerry State Department declared the Monroe Doctrine 'over' in 2013 in a speech at the Organization of American States. Kerry's statement was meant to signal that the US no longer treated Latin America as a sphere of unilateral US authority — a recognition of the failure of past interventionist policies and an acknowledgment of changed regional realities.
Trump-Era Revival
Trump and the GOP have revived the Monroe Doctrine in opposition to Chinese influence in Latin America. The framing is updated for great-power competition: instead of opposing European intervention, the contemporary Monroe Doctrine opposes Chinese economic, technological, and political influence in the Western Hemisphere.
The revived framing has appeared in:
- Concerns about Chinese BRI projects in Latin America.
- Opposition to Huawei equipment in Latin American telecom networks.
- Concerns about Chinese-financed ports and infrastructure.
- Counter-investment initiatives to provide alternatives to Chinese finance.
Why It Matters
The Monroe Doctrine has been one of the most consequential American foreign-policy frameworks of the past two centuries. Its evolution from defensive principle to interventionist justification to disavowal to revival illustrates how doctrinal frameworks can be repurposed across very different strategic contexts.
The doctrine has also shaped Latin American attitudes toward the US for two centuries — generally negatively, given the interventionist applications, though with variation by country and period.
Common Misconceptions
The Monroe Doctrine is sometimes treated as having been formally renounced. Kerry's 2013 statement was rhetorical rather than formal; the doctrine has no formal binding status that could be renounced.
Another misconception is that the doctrine was Monroe's personal creation. Most of the substantive drafting was John Quincy Adams's, though Monroe owned the political delivery.
Real-World Examples
The 1962 Cuban Missile Crisis is the most famous Cold War application of Monroe Doctrine principles. The 1904 Roosevelt Corollary transformed the doctrine for the imperial era. The 2020s revival of Monroe Doctrine language in opposition to Chinese hemispheric engagement is the contemporary application.
Example
Secretary of State John Kerry told the OAS in November 2013 that 'the era of the Monroe Doctrine is over' — a framing reversed by subsequent administrations citing Chinese hemispheric activity.
