Commonwealth (U.S. state)
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.
