From the moment the original thirteen colonies declared independence, the path to statehood was carved by compromise, principle, and a distinct desire to structure governance. While modern maps show a uniform collection of fifty states, a closer look reveals a unique subset operating under the designation of commonwealth. Kentucky, Massachusetts, Pennsylvania, and Puerto Rico (though not a state) all share this title, raising a fundamental question about why some states are commonwealths. The answer lies not in a superior legal status, but in a deliberate historical choice to enshrine the concept of popular sovereignty in their foundational documents, creating a government that exists by and for the people.
The Legal Reality: Equality Beneath the Surface
It is crucial to address a common misconception head-on: legally, a commonwealth holds no different status within the United States than a standard state. Both are subject to the same federal laws, receive the same representation in Congress (though Puerto Rico has a Resident Commissioner with limited voting rights), and are guaranteed the same constitutional protections. The designation is purely nominal, a title chosen by the people of that jurisdiction rather than being assigned by the federal government. This distinction highlights the principle of self-determination, showcasing a region that values its historical identity while operating under the exact same constitutional framework as its neighbors.
Rooted in Colonial Charters
The origins of the commonwealth title trace directly back to the original colonial charters granted by the British Crown. Massachusetts, Pennsylvania, and Kentucky were all established with documents that used the term "commonwealth" to describe their form of government. This was not an accident; it was a conscious rejection of the monarchical authority they were fighting against. By adopting the language of a commonwealth, the framers of these states explicitly rejected the idea of a government deriving its power from a king and instead asserted that their authority stemmed from the collective consent of the governed. This historical lineage is the bedrock of their modern identity.
Popular Sovereignty as a Founding Principle
At the heart of the commonwealth designation is the philosophical pillar of popular sovereignty. This concept, prominently featured in the constitutions of these states, declares that the power of the government is created by the people and exists solely to serve them. For example, the Constitution of Massachusetts famously opens with the words, "The body politic is formed by a voluntary association of individuals: it is a social compact, by which the whole people covenants with each citizen, and each citizen with the whole people." This language transforms the relationship between the citizen and the state, framing the government as an instrument of the people rather than a ruler over them.
Commonwealths vs. Standard States: A Comparative Look
While the legal powers are identical, the constitutions of commonwealths often contain distinct language that reflects their unique heritage. Unlike standard states where the constitution might focus on the rights of the state, commonwealth constitutions frequently emphasize the rights of the individual against the state. This subtle but significant rhetorical difference reinforces the idea that the government is the servant, not the master. The following table illustrates this nuanced variation in constitutional philosophy.
