Are The States Countries? | Defining Sovereignty

Many learners encounter the term “state” in different contexts, which can lead to questions about the precise nature of the fifty entities that make up the United States. Understanding the distinction between a subnational “state” and an internationally recognized “country” is fundamental to grasping political geography and constitutional structures.

Understanding “Country” and “State” in Context

The words “country” and “state” can be sources of confusion because they carry different meanings depending on the context. In international law and diplomacy, “state” often refers to a sovereign political entity, synonymous with what we commonly call a “country” or “nation-state.” This “state” possesses full independence and recognition on the global stage.

Within the United States, however, “state” refers to a subnational governmental unit. These entities, like California or New York, possess significant autonomy and their own governmental structures, but they operate under the overarching authority of the federal government of the United States.

Think of it like a large, well-organized library. The entire library building represents the United States, a single, unified entity. Inside, there are many specialized sections, each with its own rules for borrowing and organizing books, but all are part of the larger library system and follow its central policies. Each section is like a US state.

The United States as a Singular Sovereign Nation

The United States of America is the single sovereign country recognized by the international community. Its sovereignty means it has supreme authority over its territory and its people, without external interference, and it alone represents its citizens on the global stage. This unified sovereignty was established with the ratification of the U.S. Constitution.

The U.S. operates under a federal system, which means power is divided between a central national government and various regional governments (the states). While states retain considerable powers, these powers are derived from and limited by the U.S. Constitution, which is the supreme law of the land.

Historically, the period under the Articles of Confederation (1781-1789) saw states acting more like independent entities, leading to a weak central government. The subsequent U.S. Constitution created a stronger federal union, clearly defining the federal government as the ultimate sovereign authority.

What Makes a Country? Key Criteria for Nationhood

International law provides criteria for what constitutes a sovereign state (country). The Montevideo Convention on the Rights and Duties of States (1933) is widely cited for these principles. It outlines four key attributes:

• Permanent population: A stable group of people residing within its borders.
• Defined territory: A specific geographical area with recognized boundaries.
• Government: An effective political organization capable of exercising control over the territory and people.
• Capacity to enter into relations with other states: The ability to conduct foreign policy, sign treaties, and engage with other sovereign nations.

US states individually meet the first three criteria to some extent, having populations, territories, and governments. However, they critically lack the fourth criterion: the capacity to enter into relations with other states. Only the federal government of the United States possesses this international legal standing. The United Nations, for example, recognizes the United States as a member state, not its individual constituent states.

The Role and Powers of US States

Despite not being countries, US states wield significant authority within their borders. The Tenth Amendment to the U.S. Constitution reserves powers not delegated to the federal government, nor prohibited to the states, to the states respectively, or to the people. This principle is fundamental to American federalism.

Each state has its own constitution, which establishes its governmental structure, often mirroring the federal model with executive (governor), legislative, and judicial branches. States create and enforce laws on a wide range of matters that directly impact daily life.

Areas of state authority commonly include:

• Education policy and funding
• Public safety, including state police forces and criminal law
• Healthcare regulations and public health initiatives
• Transportation infrastructure, such as state highways
• Licensing for professions and businesses
• Local government structures and elections

Comparison: US State vs. Sovereign Country

Feature	US State (e.g., Texas)	Sovereign Country (e.g., Canada)
International Representation	None; represented by U.S. federal government	Direct diplomatic relations, UN membership
Currency	Uses U.S. Dollar exclusively	Issues its own national currency
Military/Defense	National Guard (under federal and state command)	Maintains independent national armed forces
Treaty-Making Power	None	Can negotiate and ratify international treaties
Citizenship	U.S. citizenship (with state residency)	Distinct national citizenship

Distinguishing Internal vs. External Sovereignty

To clarify the status of US states, it helps to differentiate between internal and external sovereignty. Internal sovereignty refers to the supreme authority a government exercises within its own borders, over its citizens and territory. US states possess a degree of internal sovereignty, creating laws and policies that apply to their residents.

However, this internal sovereignty is always subordinate to the U.S. Constitution and federal law, as established by the Supremacy Clause (Article VI, Clause 2). External sovereignty, on the other hand, refers to a state’s independence from outside control and its capacity to engage with other nations as an equal. Only the federal government of the United States holds external sovereignty.

Consider a large university system. Each campus (state) has its own dean, faculty, and specific academic programs, exercising internal authority over its students and curriculum. However, all campuses ultimately report to the university’s central administration (federal government), which handles external relations, accreditation, and overall financial policy for the entire institution.

Historical Context: From Colonies to Union

The journey from thirteen British colonies to a unified nation reveals why the states are not countries. After declaring independence in 1776, these colonies initially functioned with a high degree of autonomy. The Declaration of Independence referred to them as “Free and Independent States,” but this was in the context of their separation from Britain, not as fully separate, internationally recognized countries in perpetuity.

The framers of the Constitution deliberately created a “more perfect Union” to overcome the weaknesses of a loose confederation of sovereign states. The ratification of the Constitution in 1788-1789 solidified the concept of a single federal nation. The Civil War (1861-1865) further affirmed the indivisibility of the Union and the supremacy of federal authority over individual states’ claims to secession. The National Archives houses these foundational documents, which illustrate this historical progression.

Legal and Diplomatic Standing

The legal and diplomatic standing of the United States unequivocally demonstrates that the states are not countries. Only the U.S. federal government can:

• Declare war or make peace.
• Negotiate and ratify international treaties.
• Issue passports and visas.
• Establish diplomatic relations with foreign governments.
• Regulate interstate and international commerce.
• Coin money and regulate its value.

Individual states cannot perform any of these functions. A citizen of California, for instance, holds U.S. citizenship, not Californian citizenship in the international sense. When traveling abroad, they present a U.S. passport, and any diplomatic assistance required would come from a U.S. embassy or consulate.

Federal vs. State Powers in the United States

Area of Governance	Federal Government Power	State Government Power
Foreign Policy & Defense	Declare war, maintain armed forces, negotiate treaties	None (National Guard is shared, but federalized)
Currency & Banking	Coin money, regulate currency, national banking laws	Charter state banks, regulate intrastate financial services
Interstate Commerce	Regulate trade between states and with foreign nations	Regulate commerce solely within state borders
Law Enforcement	FBI, federal courts, enforce federal laws	State police, local police, state courts, enforce state laws
Education	Limited federal role (e.g., funding, standards)	Primary responsibility for public education systems
Taxation	Income tax, corporate tax, tariffs	Sales tax, property tax, state income tax
