Named after
King Louis XVI of France, Louisville was founded in 1778 by
George Rogers Clark, making it one of the oldest cities west of the
Appalachians.
[13] With the nearby
Falls of the Ohio as the only major obstruction to river traffic between the upper
Ohio Riverand the
Gulf of Mexico, the settlement first grew as a
portage site. It was the founding city of the
Louisville and Nashville Railroad, which grew into a 6,000-mile (9,700 km) system across 13 states.
Today, the city is known as the home of boxer
Muhammad Ali, the
Kentucky Derby,
Kentucky Fried Chicken, the
University of Louisville and its
Cardinals,
Louisville Slugger baseball bats, and
Fortune 500 company
Humana.
[14][15]Louisville Muhammad Ali International Airport, the city's main commercial airport, hosts
UPS'sworldwide hub.
Since 2003, Louisville's borders have been the same as those of Jefferson County, after a
city-county merger.
[16] The official name of this consolidated city-county government is the Louisville/Jefferson County Metro Government,
[17] abbreviated to Louisville Metro.
[18] Despite the merger and renaming, the term "Jefferson County" continues to be used in some contexts in reference to Louisville Metro, particularly including the
incorporated cities outside the "
balance" which make up Louisville proper. The city's total consolidated population as of the
2020 census was 782,969.
[19] However, the balance total of 633,045
[20] excludes other incorporated places within the county and is the population listed in most sources and national rankings.
