Nashville, often known as Music City,[9] is the capital and most populous city in the U.S. state of Tennessee and the county seat of Davidson County. Located in Middle Tennessee, it had a population of 689,447 at the 2020 U.S. census.[d] Nashville is the 21st most populous city in the United States, and the fourth most populous city in the southeastern U.S.[6] Located on the Cumberland River,[10] the city is the center of the Nashville metropolitan area, and is one of the fastest growing in the nation.[11][12] Named for Francis Nash, a general of the Continental Army during the American Revolutionary War, the city was founded in 1779 when this territory was still considered part of North Carolina. The city grew quickly due to its strategic location as a port on the Cumberland River and, in the 19th century, a railroad center. Nashville as part of Tennessee seceded during the American Civil War; in 1862 it was the first state capital in the Confederacy to be taken by Union forces. It was occupied through the war. After the war, the city gradually reclaimed its stature. It became a center of trade and developed a manufacturing base. Since 1963, Nashville has had a consolidated city-county government, which includes six smaller municipalities in a two-tier system. The city is governed by a mayor, a vice-mayor, and a 40-member metropolitan council. Some 35 of the members are elected from single-member districts, while five are elected at-large. Reflecting the city's position in state government, Nashville is home to the Tennessee Supreme Court's courthouse for Middle Tennessee, one of the state's three divisions.
