The phrase “the 51st state” is used to describe a place that is not currently a U.S. state but is sometimes discussed as a potential one, or to refer to places closely aligned with or compared to the United States. This explainer outlines the expression’s origins, its application to U.S. territories and other countries, and the legal and political realities behind the term. It is designed to provide a clear, factual reference for understanding how and why the phrase is used in political, cultural, and diplomatic contexts.
Origins and Historical Usage
The idea of a 51st state has existed since the admission of Hawaii as the 50th state in 1959. Before that, discussions about future states such as Puerto Rico, Washington, D.C., and other territories appeared in policy debates. The phrase gained cultural traction in the late 20th century as a way to describe places that were informally tied to the United States or seen as candidates for statehood. Over time, it also became a metaphor for countries with strong political, economic, or cultural ties to the U.S.
Puerto Rico and Washington, D.C.
Two locations are most frequently mentioned in serious discussions about a 51st state: Puerto Rico and Washington, D.C. Puerto Rico is a U.S. territory whose residents are U.S. citizens but who do not have voting representation in Congress. Washington, D.C. is the federal capital, which has limited voting representation and is often cited in debates about political equality and home rule. Both are long-standing subjects of legal and legislative consideration.
How the Phrase Is Used Today
In contemporary usage, “the 51st state” can refer to several different situations. It may describe a U.S. territory that could become a state, a location with close ties to the United States, or even a country that is heavily influenced by American culture or policy. Sometimes the term is used critically to suggest that a country is too dependent on the U.S., while other times it is used neutrally to describe potential statehood candidates.
- U.S. territories with ongoing debates about statehood or greater autonomy
- Countries that maintain strong diplomatic, military, or economic ties with the United States
- Regions considered culturally aligned with American norms and media
Puerto Rico: Statehood and Political Status
Puerto Rico’s position as a potential 51st state is grounded in its history as a U.S. territory acquired in 1898. Puerto Ricans have been U.S. citizens since 1917 and have participated in several status referendums, with varying levels of support for statehood, independence, or maintaining current territorial status. Congress would need to act to admit Puerto Rico as a state, and any change would require navigating questions of language, representation, and fiscal policy.
Key Facts on Puerto Rico’s Status
| Attribute | Verified Detail | Source Type |
|---|---|---|
| Current Status | U.S. unincorporated territory | U.S. Constitution, federal law |
| Citizenship | U.S. citizens by birth | Jones–Shafroth Act of 1917 |

Washington, D.C.: Representation and Governance
Washington, D.C., established by the U.S. Constitution as the seat of federal government, is not a state and does not have voting representation in Congress. The home rule charter allows for local governance on many matters, but Congress retains the power to review and overturn local laws. Proposals for statehood—often framed as the State of Washington, Douglass Commonwealth or similar names—have been debated for decades, highlighting issues of representation and constitutional interpretation.
D.C. Statehood Considerations
- Constitutional questions about the federal district clause
- Political debates regarding balance of power in Congress
- Local support for full voting representation
Other Territories and Potential Candidates
Beyond Puerto Rico and Washington, D.C., other U.S. territories include Guam, the U.S. Virgin Islands, the Northern Mariana Islands, and American Samoa. While these jurisdictions have U.S. citizens or nationals and are subject to federal laws, none have moved actively toward statehood. Their considerations involve population size, economic structure, and strategic factors. Meanwhile, the notion of other countries becoming “the 51st state” is generally rhetorical, used to express strong alliance or influence rather than a literal political trajectory.
Legal and Political Realities
For any place to become a U.S. state, it must be admitted by Congress under Article IV, Section 3 of the Constitution. That process involves political negotiations, legal reviews, and often public referendums where applicable. International law governs relationships between sovereign states, and no country can become a part of the United States without its own consent. Terms like “protectorate” or “associated state” describe different forms of relationship that fall short of statehood.
International Comparisons and Cultural Influence
Outside the United States, the phrase “51st state” is sometimes used to describe countries that are closely aligned with U.S. foreign policy or host significant American military or business interests. These comparisons are generally symbolic and do not imply legal integration. They reflect cultural influence, economic connections, or strategic partnerships rather than any intent or plan for annexation.
Common Misconceptions and Rumor Risk
Rumors occasionally circulate suggesting imminent statehood for a particular territory or that a country is being positioned to become the 51st state. Such claims often lack a basis in current law or legislative strategy. While discussions about statehood can evolve, they require deliberate action by Congress and, in many cases, local support. It is important to distinguish between metaphorical usage, aspirational advocacy, and actual legal processes.
Conclusion and Status Clarification
“The 51st state” is a flexible term that can refer to potential U.S. states, territories with close ties to the United States, or countries heavily influenced by American policy. In the present day, only U.S. states have full representation and sovereignty within the federal system. Territories such as Puerto Rico and Washington, D.C. remain in long standing legal and political processes that could, in time, alter their status. Until such changes occur, the phrase will continue to serve as a symbol rather than a description of existing political reality.
Understanding the phrase clearly requires separating symbolic language from the legal frameworks that define statehood. By doing so, it becomes easier to interpret references to the 51st state in news coverage, political speeches, and public debates. This clarity supports informed discussion about the future of U.S. territories, the balance of representation, and the limits of constitutional change.
