Somerset is a home rule-class city in Pulaski County, Kentucky, United States. The city population was 11,196 according to the 2010 census. It is the seat of Pulaski County.
Somerset was first settled in 1798 by Thomas Hansford and received its name from Somerset County, New Jersey, where some of the early settlers had formerly lived. Somerset became the Pulaski County seat in 1802, and it was incorporated as a city in 1887. A significant Civil War battle was fought in January 1862, at Mill Springs (now "Nancy") about 8 miles (13 km) west of Somerset, and a museum is at the site. A smaller battle was fought nearby at Dutton's Hill in 1863. In 1875 tracks for the Southern Railroad were completed and Somerset saw a sudden population growth and an increase in industry. In the late 1930s and early 1940s, library services were provided by the pack horse library. The completion of Lake Cumberland in 1950 transformed Somerset from a sleepy rural community into one of the largest recreation centers in Kentucky, drawing more than 1.7 million visitors annually, especially between the Memorial and Labor Day holidays.
