Mercer County is a county located in the U.S. state of Kentucky. As of the 2010 census, the population was 21,331.  Its county seat is Harrodsburg.  The county was formed from Lincoln County, Virginia in 1785  and is named for Revolutionary War General Hugh Mercer, who was killed at the Battle of Princeton in 1777. 
It is a prohibition or dry county, though Harrodsburg and Pleasant Hill allow the sale of alcohol by the drink. In Kentucky this is referred to as being a "moist" county; wet counties sell package liquor, wine and beer, dry counties sell no alcoholic beverages (legally), while "moist" counties serve only by the drink, primarily in restaurants. Boyle County (Danville) immediately to the south along US Hwy 127, is wet, with two large liquor outlet stores, plus several smaller, privately owned ones.
Harrodsburg was the first city formally chartered in Kentucky County, the Virginia territory that later became the 15th state. It was originally the county seat of Lincoln County when it was formed in 1780, but it became the seat of Mercer County when it was created.
Pleasant Hill, also known as Shakertown, is the site of a former Shaker community, active especially in the years before the American Civil War. It is a National Historic Landmark District, consisting of more than 30 historic buildings. The district also includes acres of farm and parkland.
During the Civil War, the county was divided in sentiment. Union control permitted the organization 2 Union regiments, the 19th Regiment Kentucky Volunteer Infantry and the 11th Regiment Kentucky Volunteer Cavalry. However, many county men also served in the Confederate Army. The 19th Kentucky Infantry (Union)was organized at Camp Harwood for a three-year enlistment commencing January 2, 1862, commanded Col. William J. Landram. Companies A, C, D, and F of the 11th Kentucky Cavalry (Union) were organized at Harrodsburg in July 1862. The remainder of the regiment was organized in Louisville, Kentucky, and mustered in for three years on September 26, 1862, under the Colonel Alexander W. Holeman. Following the Battle of Perryville, much of Harrodsburg and surrounding towns were converted into makeshift hospitals; 1600 sick and wounded Confederate soldiers were captured during a raid in Harrodsburg by the 9th Kentucky Cavalry on October 10, 1862. The city then remained under martial law for the remainder of the war.[ citation needed]
The Louisville Southern Railroad reached Harrodsburg in 1888. Louisville Southern Railway's construction commenced in 1884 and ran from Louisville through Shelbyville and Lawrenceburg to Harrodsburg, which was reached in 1888. The rail yard and station were located at the corner of Office Street and Merimon Avenue. A spur was later constructed from the station to Burgin, where the Louisville Southern joined the Cincinnati Southern's Cincinnati, New Orleans and Texas Pacific Railway CNO&TP mainline which runs through the eastern part of the country from High Bridge of Kentucky to Burgin to Danville was opened in 1877. Now all run and operated by Norfolk Southern Railway.
