Map - Davidson County, Tennessee (Davidson County)

Davidson County is a county in the U.S. state of Tennessee. It is located in the heart of Middle Tennessee. As of the 2020 census, the population was 715,884, making it the second most populous county in Tennessee. Its county seat is Nashville, the state capital and largest city.

Since 1963, the city of Nashville and Davidson County have had a consolidated government called the "Metropolitan Government of Nashville and Davidson County", commonly referred to as "Metro Nashville" or "Metro".

Davidson County has the largest population in the 13-county Nashville-Davidson–Murfreesboro–Franklin Metropolitan Statistical Area, the state's most populous metropolitan area. Nashville has always been one of the region's centers of commerce, industry, transportation, and culture, but it did not become the capital of Tennessee until 1827 and did not gain permanent capital status until 1843.

Davidson County is the oldest county in the 41-county region of Middle Tennessee. It dates to 1783, shortly after the end of the American Revolution, when the North Carolina legislature created the county and named it in honor of William Lee Davidson, a North Carolina general who was killed opposing the crossing of the Catawba River by General Cornwallis's British forces on February 1, 1781. The county seat, Nashville, is the oldest permanent European settlement in Middle Tennessee, founded by James Robertson and John Donelson during the winter of 1779–80 and the waning days of the Revolutionary War.

The first white settlers established the Cumberland Compact to establish a basic rule of law and to protect their land titles. Through much of the early 1780s, the settlers also faced a hostile response from the Native American tribes, such as the Cherokee, Muscogee (Creek), and Shawnee who while not living in the area used is as a hunting ground and resented the newcomers moving into there and competing for its resources. As the county's many known archaeological sites attest, Native American cultures had occupied areas of Davidson County for thousands of years. The first white Americans to enter the area were fur traders. Long hunters came next, having heard about a large salt lick, known as French Lick, where they hunted game and traded with the Native Americans.

In 1765, Timothy Demonbreun, a hunter, trapper, and former Governor of Illinois under the French, and his wife lived in a small cave (now known as Demonbreun's Cave) on the south side of the Cumberland River near present-day downtown Nashville. They were the parents of the first white child to be born in Middle Tennessee. A number of the settlers came from Kentucky and the Upper South. Since the land was fertile, they cultivated hemp and tobacco, using the labor of enslaved African Americans, and also raised blooded livestock of high quality, including horses. Generally holding less land than the plantations of Western Tennessee, many Middle Tennessee planters nevertheless became wealthy during this period.

Davidson County was much larger when it was created in 1783. However, four more counties were carved out of Davidson County's territory between 1786 and 1856.

* Sumner County created in 1786

* Williamson County, created in 1799

* Rutherford County, created in 1803 (also included parts of Wilson County)
