Shelby County was created as a county of the Territory of Alabama by the Territorial General Assembly on February 7, 1818. Carved from the northern portion of Montgomery County, it included the area which has been further divided into Jefferson, Chilton, St Clair and Talladega counties. The county is named for Isaac Shelby, a hero of the Battle of King's Mountain in the Revolutionary War who was also the first governor of Kentucky.
It became part of the new State of Alabama upon its admission to the Union in December 1819. The first courthouse, built in 1820, was located in the community of Shelbyville, now within the corporate limits of Pelham. The county seat was moved to Columbia in 1826, with an old school serving as the courthouse. In 1832 Columbia was renamed "Columbiana" and remains the seat of Shelby County.
The 2010 U. S. Census enumeration of Shelby County's population is 195,085. Shelby County is ranked as the fastest growing county in Alabama and is one of the fastest growing counties in the country.
Shelby County was created from area ceded to the Territory of Alabama by the Treaty of Fort Jackson in 1814. The first non-Indian homesteaders arrived shortly thereafter from Kentucky, South Carolina and Tennesee, settling predominantly in the Cahaba Valley near Shoal Creek. The first towns to spring up were Wilson's Hill (Montevallo) and Shelbyville (Pelham). Other towns followed in the Coosa Valley, including Bigs Springs (Harpersville) and Wilsonville.
The first court business was conducted at William Wallace's residence in Shelbyville. Following the admission of Alabama to the United States, Shelbyville was set as a the county seat and a courthouse was erected in 1820. The seat was moved to Columbia (Columbiana) in 1826 because of its more central location. The 1826 courthouse served until a new brick structure was erected in 1854. The present Shelby County Courthouse was constructed in 1906.
According to the U.S. Census Bureau, the county has a total area of 810 mi². 795 mi² of it is land and 15 mi² of it (1.83%) is water.
