Spencer County, Kentucky: History
Spencer County was formed in January 1824, by the 32nd Kentucky General Assembly. The land that now makes up Spencer County was taken from Bullitt County, Shelby County, and Nelson County. Spencer County became Kentucky's 77th county. The county was named for Kentucky's Captain Spier Spencer, who fought and died in the Battle of Tippecanoe.
Later that year, in December 1824, Taylorsville was made the county seat. In 1829, the city was incorporated.
During the American Civil War, the courthouse at Taylorsville was burned by Confederate guerrillas in January 1865, but the county's records were saved.
