Jefferson County was established in 1780, along the banks of the Ohio River. It is the largest county in the state.
In 2003, the Jefferson County government merged with that of Louisville, its largest city and county seat, forming the Louisville-Jefferson County Metro Government, known as Louisville Metro.
Jefferson County is the birthplace of boxer Muhammad Ali, baseball great Pee Wee Reese, and the 12th President of the United States, Zachary Taylor. It is, also, home to Churchill Downs, the Belle of Louisville, and the Louisville Slugger.
