Pennsylvania is one of four states in the Union—alongside Kentucky, Massachusetts, and Virginia—that officially designates itself as a commonwealth rather than a state. This distinction often sparks curiosity among residents, students, and visitors alike. While the term carries a certain historical weight and ceremonial gravitas, the legal reality is straightforward: there is no constitutional difference between a commonwealth and a state within the United States. Both possess the same relationship to the federal government, the same powers reserved under the Tenth Amendment, and the same representation in Congress. The difference lies entirely in history, political philosophy, and the specific vocabulary chosen by the founders of these jurisdictions to describe their new governments during the revolutionary era.
The Historical Roots of the Term
To understand why Pennsylvania adopted this specific label, one must look at the linguistic and political climate of the late 18th century. The word commonwealth derives from the older phrase "the common weal" or "common weal," meaning the common good, public welfare, or the well-being of the community as a whole. It was a term deeply rooted in English political thought, particularly during the Interregnum period (1649–1660) when Oliver Cromwell established the Commonwealth of England after the execution of King Charles I.
For the American revolutionaries, the term was a deliberate rejection of monarchical language. On top of that, it signaled a government where sovereignty resided in the people—popular sovereignty—rather than in a crown. A "state" could theoretically exist under a king; a "commonwealth" implied a political community founded on the consent of the governed for the collective benefit. When the thirteen colonies severed ties with Great Britain, they needed new frameworks for governance. Pennsylvania’s leaders chose language that reflected their radical democratic ideals.
The official docs gloss over this. That's a mistake.
The 1776 Constitution: A Radical Experiment
Pennsylvania’s first constitution, ratified on September 28, 1776, is widely considered the most democratic of the original state constitutions. Drafted by a convention that included figures like Benjamin Franklin, George Bryan, and James Cannon, it was heavily influenced by the political theories of the French philosopher Montesquieu and the radical Whig tradition.
The preamble of the 1776 Constitution explicitly states: "We, the representatives of the freemen of Pennsylvania, in general convention met, for the express purpose of framing such a government, confessing the goodness of the Great Governor of the universe... do establish, declare, and ordain the following Declaration of Rights and Frame of Government, to be the Constitution of this Commonwealth."
Honestly, this part trips people up more than it should.
Notice the deliberate choice of words. In practice, " It establishes the "Commonwealth of Pennsylvania. That said, " This was not an accident. The framers wanted to point out that the new government was a res publica—a public affair—owned collectively by the citizenry. Worth adding: the document does not say "State of Pennsylvania. The 1776 Constitution also featured a unicameral legislature (a single house) and a plural executive (a Supreme Executive Council led by a President rather than a single Governor), structures designed to prevent the concentration of power that characterized a monarchy. The label "commonwealth" was the linguistic capstone on this architectural rejection of royal authority.
Legal Equivalence: Commonwealth vs. State
Despite the lofty rhetoric of 1776, the legal status of Pennsylvania did not change when the U.S. Constitution was ratified in 1787. Article IV, Section 3 of the U.Worth adding: s. Constitution grants Congress the power to admit new states into the Union. It does not mention commonwealths. When Pennsylvania ratified the federal Constitution on December 12, 1787, becoming the second state to do so, it entered the Union on exactly the same footing as Delaware, New Jersey, or Georgia.
Today, the Pennsylvania Constitution (the current version dates to 1968, though it retains the 1776 preamble language in spirit) uses the terms "Commonwealth" and "State" interchangeably in various sections. Because of that, for example, Article I, Section 1 declares: "All men are born equally free and independent, and have certain inherent and indefeasible rights... To protect these rights, governments are instituted among men, deriving their just powers from the consent of the governed." The document refers to the "Government of the Commonwealth" but also references the "State" in contexts involving interstate compacts or federal relations.
Key Takeaway: Legally, Pennsylvania is a state. The label "Commonwealth" is a stylistic, historical, and symbolic choice retained in the state's official name: The Commonwealth of Pennsylvania. It appears on the state seal, in the oath of office for public officials, and in the formal titles of state agencies (e.g., the Pennsylvania State Police are technically the "Pennsylvania State Police," but the courts are the "Unified Judicial System of Pennsylvania" operating under the authority of the Commonwealth) No workaround needed..
The Other Three: A Shared Revolutionary Vocabulary
Pennsylvania was not alone in this nomenclature. Understanding the company it keeps helps contextualize the decision.
- Virginia: The oldest of the four, Virginia adopted the title "Commonwealth" in its 1776 constitution, drafted by George Mason and James Madison. Like Pennsylvania, it was a declaration of independence from the Crown and an assertion of popular sovereignty.
- Massachusetts: The 1780 Constitution of Massachusetts, largely written by John Adams, formally styled the government "The Commonwealth of Massachusetts." Adams was a student of classical republicanism and specifically chose the term to denote a republic aimed at the public good.
- Kentucky: Originally a county of Virginia, Kentucky retained the "Commonwealth" designation when it achieved statehood in 1792, simply carrying forward the legal and cultural identity of its parent jurisdiction.
All four share a common thread: they were either original colonies or direct offshoots of an original colony that formed their governments during the American Revolution, before the U.Worth adding: s. Constitution standardized the term "state" in federal law Not complicated — just consistent..
Symbolism and Modern Usage
In the 21st century, the designation serves primarily as a point of pride and historical identity. " Prosecutors bring cases in the name of the "Commonwealth" (e.When the Governor delivers the annual budget address, it is the "Commonwealth Budget.In real terms, smith*), a practice familiar to viewers of legal dramas but distinct from the "People v. Now, g. It distinguishes Pennsylvania in ceremonial contexts. And smith" or "State v. , *Commonwealth v. Smith" formatting used in other jurisdictions.
This prosecutorial phrasing—Commonwealth v. That's why defendant—is perhaps the most frequent interaction citizens have with the term. It reinforces the theoretical underpinning: the prosecution represents the collective people, the "common weal," seeking justice on behalf of the community rather than the government as a separate entity Still holds up..
Most guides skip this. Don't.
What's more, the term appears in the names of key institutions:
- Commonwealth Court of Pennsylvania: One of the two intermediate appellate courts.
- Commonwealth Financing Authority: An independent agency administering economic development programs.
- Pennsylvania Commonwealth Libraries: The state library agency.
Common Misconceptions
Because the term is unusual, several myths persist regarding its implications Nothing fancy..
Myth 1: Commonwealths have more autonomy than states. Reality: False. The Supremacy Clause of the U.S. Constitution applies equally to all 50 states. Federal law trumps state (or commonwealth) law in areas of federal jurisdiction. Pennsylvania has no special veto power, no unique treaty-making ability, and no different tax relationship with the IRS It's one of those things that adds up..
Myth 2: "Commonwealth" implies a specific economic system (like socialism or a welfare state). Reality: False. The 18th-century definition of "common weal" simply meant "public welfare" or "common good." It predates modern economic ideologies by over a century. It
It does not prescribe any particular model of taxation, ownership, or redistribution; rather, it reflects a philosophical commitment to governance that prioritizes the welfare of the populace as a whole.
Myth 3: Only the four “commonwealth” states can use the term in official symbols.
Reality: While Pennsylvania, Kentucky, Massachusetts, and Virginia are the only states that retain “Commonwealth” in their formal names, other jurisdictions—such as Puerto Rico and the Northern Mariana Islands—adopt the designation for their own political status, and numerous municipalities, schools, and organizations across the country incorporate the word into their titles to evoke a sense of shared purpose.
Conclusion
The enduring use of “Commonwealth” in these four states is less a legal distinction than a cultural emblem, linking modern governance to the republican ideals of the Revolutionary era. Though the term carries no special privileges or obligations under federal law, it continues to shape ceremonial language, judicial nomenclature, and institutional branding, reminding citizens that governmental authority is ultimately exercised for the common good. In a nation where state identities often blur, the Commonwealth designation offers a distinctive narrative of collective responsibility—one that persists as a point of pride and a subtle invitation to view public service as a shared endeavor rather than a mere administrative function And it works..
