Knoxville is a city in the U.S. state of Tennessee, and the county seat of Knox County. The city had an estimated population of 185,291 in 2015 and a population of 178,874 as of the 2010 census, making it the state's third largest city after Nashville and Memphis.
First settled in 1786, Knoxville was the first capital of Tennessee. The city struggled with geographic isolation throughout the early 19th century. The arrival of the railroad in 1855 led to an economic boom. During the American Civil War, the city was bitterly divided over the secession issue, and was occupied alternately by both Confederate and Union armies. Following the war, Knoxville grew rapidly as a major wholesaling and manufacturing center.
