From the moment the original thirteen colonies declared independence, the path to becoming a state was carved with distinct legal traditions and political experimentation. While the vast majority of American states operate under a standard constitutional framework, a handful chose a different designation, identifying themselves as commonwealths. Kentucky, Massachusetts, Pennsylvania, and Virginia proudly bear this title, a living link to the philosophical debates of the founding era. The question of why some states are commonwealths is not merely a matter of semantics; it is a window into the unique historical pressures and ideological convictions that shaped the American union.
The Legal Distinction: Form vs. Substance
At the federal level, the United States government recognizes no legal distinction between a state and a commonwealth; both possess equal sovereignty and are represented identically in Congress and before the Supreme Court. The difference is purely nominal, residing in the specific language of their original state constitutions. A commonwealth is essentially a state that deliberately chose to define itself through a constitution that explicitly references its status as a "commonwealth" rather than a "state." This choice was often a deliberate throwback to Enlightenment thinking, invoking the concept of government existing for the "common good" rather than the crown.
Historical Roots in Republican Ideology
The use of the term "commonwealth" harks back to the political philosophy of the 17th and 18th centuries, particularly in England and its American colonies. It implied a government founded for the collective welfare of the people, a "common weal," as opposed to a monarchy that served the interests of a ruling dynasty. When these four states drafted their constitutions—Pennsylvania in 1776, Massachusetts in 1780, Virginia in 1776, and Kentucky in 1792—they were making a conscious ideological statement. They were rejecting the colonial past and embracing a vision of popular sovereignty where the government was the servant, not the master, of the people.
Why These Four States Specifically?
The designation was not a random trend but a reflection of the unique political climate and leadership in each jurisdiction during their formative years. Pennsylvania, under the radical thinker Benjamin Franklin, was a hotbed of democratic experimentation seeking to create a government explicitly for the common citizen. Virginia, the old Dominion, carried the legacy of its self-governance during the colonial period and sought to enshrine that independence in its new identity. Massachusetts, driven by a Puritan sense of communal covenant, saw the commonwealth as a "city upon a hill" bound by a social contract. Kentucky, the last to join the union in this group, adopted the title as it separated from Virginia, cementing its own distinct identity rooted in the revolutionary ideals of its parent state.
