History and Facts of Kentucky Counties

Before Statehood Kentucky was part of Virginia. In 1776, the counties of Virginia beyond the Appalachian Mountains became known as Kentucky County.

Kentucky County was abolished on June 30, 1780, when it was divided into Fayette, Jefferson, and Lincoln counties of Virginia.

Eventually, the residents of Fayette, Jefferson, and Lincoln counties petitioned for a separation from Virginia. Ten constitutional conventions were held in Danville between 1784 and 1792, in the Constitution Square Courthouse.

On December 18, 1789, Virginia gave its consent to Kentucky statehood. The U.S. Congress gave its approval on February 4, 1791. Kentucky officially became the 15th state in the Union on June 1, 1792.

Kentucky is currently divided into 120 counties. States bordering Kentucky are IllinoisIndianaMissouriOhioTennesseeVirginia, and West Virginia.
