Prior to the European colonization of North America, the county had been inhabited by various cultures of Native Americans for several thousand years. Nomadic Paleo and Archaic hunter-gatherer campsites, as well as substantial Woodland and Mississippian-period occupation sites and burial grounds, can be found scattered throughout the county. The majority of these sites exist along natural waterways, with the highest concentration occurring along what is now known as the Cumberland River. Mississippian period earthwork mounds can still be seen in Hendersonville, and most notably, at Castalian Springs. Long before Europeans entered the area, Native Americans made use of the natural springs for their medicinal and healing properties. Longhunters traveled into the area as early as the 1760s, following existing Indian and buffalo trails. By the early 1780s, they had erected several trading posts in the region. The most prominent was Mansker's Station, which was built by Kasper Mansker near a salt lick (where modern Goodlettsville would later develop). Isaac Bledsoe built Bledsoe's Station at Castilian Springs. Around the same time Captain William Asher established Asher’s Station along Station Camp Creek near modern Gallatin. Together, these three stations served as the first defensive forts erected in what would later become Sumner County. The county was officially organized in 1786, just 3 years after the end of the American Revolutionary War, when Tennessee was still the western part of North Carolina. During the 19th century, the county was developed for agriculture: tobacco and hemp, and blooded livestock. Numerous settlers came from central Kentucky's Bluegrass Region, where these were the most important products. Middle Tennessee had fertile lands that could be used for similar crops and supported high-quality livestock as well. The larger planters depended on the labor of enslaved African Americans. Infrastructure built to support the housing of slaves during this time still exists in Gallatin. During the American Civil War, most of Tennessee was occupied by Union troops from 1862. This led to a breakdown in civil order in many areas. The Union commander, Eleazer A. Paine, was based at Gallatin, the county seat. He was notoriously cruel and had suspected spies publicly executed without trial in the town square. He was eventually replaced because of his mistreatment of the people. In 1873, the county was hit hard by the fourth cholera pandemic of the century, which had begun about 1863 in Asia. It eventually reached North America and was spread by steamboat passengers who traveled throughout the waterways, especially in the South on the Mississippi River and its tributaries. An estimated 120 persons died of cholera in Sumner County in 1873, mostly during the summer. The disease was spread mainly through contaminated water, due to the lack of sanitation. About four-fifths of the county's victims were African Americans. Many families, both black and white, lost multiple members. In the United States overall, about 50,000 persons died of cholera in the 1870s. On April 17 and 27, 2019, eight bodies were discovered at multiple locations in Sumner County. The sole survivor, left in critical condition, died in 2022 due to major health problems after the injuries. A suspect, identified as Michael Cummins, was arrested for all nine attacks.

• Illustration — Signs indicating the Tennessee State and Sumner County borders According to the U.S. Census Bureau, the county has a total area of 543 sqmi, of which 529 sqmi is land and 14 sqmi (2.5%) is water. Sumner County is located in Middle Tennessee on the state's northern border with Kentucky. The Cumberland River was important in early trade and transportation for this area, as it flows into the Ohio River to the west. That leads to the Mississippi River, and downriver to the major port of New Orleans. Sumner County is in the Greater Nashville metropolitan area.

Submarine innovator Horace Lawson Hunley was born in Sumner County on June 20, 1823. On October 15, 1863, Hunley, along with seven other crewmen, drowned while making a test dive in Charleston Harbor near Fort Pinckney. Following his death, the submarine, unofficially known as the "Fish Boat," was renamed the H.L. Hunley in his honor. On the night of February 17, 1864, the Hunley sank the Housatonic, making it the first submarine to sink an enemy vessel. Watergate prosecutor and criminal defense trial lawyer James F.
