Kentucky is home to a number of unique facts and traits that set it apart from other U.S. states. From being one of only four commonwealths in the country to having continuous river borders on three sides, Kentucky's geography and history make it a truly distinctive state.

Why it matters

Kentucky's distinct identity and quirky facts highlight how the state's history, geography, and culture have evolved in a way that is unlike anywhere else in the country. These unique characteristics contribute to Kentucky's appeal as a travel destination and showcase the state's individuality.

The details

Kentucky is one of only four U.S. commonwealths, along with Pennsylvania, Virginia, and Massachusetts. The state's founders, mostly Virginians, wanted a government dedicated to the "common good" rather than monarchical rule. Kentucky is also the only commonwealth that wasn't an original colony. Additionally, Kentucky is the only place in the Western Hemisphere where you can see a moonbow, a rainbow created by moonlight and the mist from Cumberland Falls. Every elected official and attorney being sworn in Kentucky must also swear that they have never participated in a duel using deadly weapons. Geographically, Kentucky is the only state with continuous river borders on three of its sides - the Mississippi River on the west, the Ohio River on the north, and the Big Sandy and Tug Fork rivers to the east.

  • Kentucky became a commonwealth in 1792 after separating from Virginia.
