The term "commonwealth" does not describe or provide for any specific political status or legal relationship when used by a state. Those that do use it are equal to those that do not. A traditional English term for a political community founded for the common good, it is used symbolically to emphasize that these states have a "government based on the common consent of the people" as opposed to one legitimized through their earlier colonial status that was derived from the British crown. It refers to the common "wealth", or welfare, of the public and is derived from a loose translation of the Latin term res publica. Criminal charges in these four states are brought in the name of the Commonwealth. Besides the four aforementioned states, other states have also on occasion used the term commonwealth to refer to themselves:
The term commonwealth is used interchangeably with the term state in the Constitution of Vermont.
Delaware was primarily referred to as a "state" in its 1776 Constitution; however, the term commonwealth was also used in one of its articles.
Two U.S. territories are also designated as commonwealths: Puerto Rico and the Northern Mariana Islands. When used in connection with areas under U.S. sovereignty that are not states, the term broadly describes an area that is self-governing under a constitution of its own adoption and whose right of self-government will not be unilaterally withdrawn by the United States Congress.
States
Kentucky
On September 28, 1786, the residents of Kentucky County began petitioning the Virginia legislature for permission to become a "free and independent state, to be known by the name of the Commonwealth of Kentucky". On June 1, 1792, Kentucky County officially became a state. As in Virginia, the official title of the elected local prosecutor in each of Kentucky's political subdivisions is the Commonwealth's Attorney, as opposed to State's Attorney in other states or the more standard District Attorney. Kentucky is the only state outside of the original Thirteen Colonies that uses commonwealth in its name.
The Seal of Pennsylvania does not use the term, but legal processes are in the name of the Commonwealth, and it is a traditional official designation used in referring to the state. In 1776, Pennsylvania's first state constitution referred to it as both Commonwealth and State, a pattern of usage that was perpetuated in the constitutions of 1790, 1838, 1874, and 1958. One of Pennsylvania's two intermediate appellate courts is called the Commonwealth Court.
Virginia
The name Commonwealth of Virginia dates back to its independence from the Kingdom of Great Britain. Virginia's first constitution directed that "Commissions and Grants shall run, In the Name of the commonwealth of Virginia, and bear test by the Governor with the Seal of the Commonwealth annexed." The Secretary of the Commonwealth still issues commissions in this manner. Among other references, the constitution furthermore dictated that criminal indictments were to conclude "against the peace and dignity of the Commonwealth". Additionally, the official title of the elected local prosecutor in each of Virginia's political subdivisions is the Commonwealth's Attorney, as opposed to State's Attorney in other states or the more standard District Attorney. In Virginia, the term state is sometimes used in an official manner, usually in a compound structure rather than as a standalone noun. This is evident in the names of the Virginia State Corporation Commission, the Virginia State Police, and the Virginia Polytechnic Institute and State University. The state university in Richmond is known as Virginia Commonwealth University; there is also a Virginia State University, located in Ettrick.
