Kentucky, officially the Kentucky Commonwealth, is a state situated in the United States ' south-central east region. Although named in the statute establishing it as the "State of Kentucky" (because the word "state" was used in the first constitution of Kentucky), Kentucky is one of four U.S. states known as a commonwealth (the others being Virginia, Pennsylvania, and Massachusetts). Initially a member of Virginia, Kentucky broke away from it in 1792 and became the fifteenth state to join the Union. Kentucky is the 37th largest and the 26th most populous of the 50 U.S.
Kentucky is named the "Bluegrass State" a bluegrass-based term, a grass species found in many of its pastures. One of Kentucky's main areas is the Bluegrass region in central Kentucky, home to two of its biggest cities, Louisville and Lexington. It is a land with diverse environments and abundant resources, including the longest cave system in the world, Mammoth Cave National Park, one of the largest lengths of navigable waterways and streams in the adjacent United States, and the two largest man-made lakes east of the Mississippi River.
Kentucky Governor Paul Patton unveiled the state slogan "It's that friendly" in December 2002, hoping to attract more people to the state on the basis of the idea of southern hospitality. Although this initiative was intended to promote southern ideals, most Kentuckians dismissed the message as simplistic and ineffective. It was soon seen that tourism was not motivated by the slogan as much as originally hoped. So the government decided to create a new slogan to embrace Kentucky as a whole while encouraging more people to visit the Bluegrass.
