Knoxville is a city in Marion County, Iowa, United States. The population was 7,313 at the 2010 census. It is the county seat of Marion County. Knoxville is home of the National Sprint Car Hall of Fame & Museum located next to the famous dirt track known as Knoxville Raceway.
The site for the future county seat of Marion County was selected because it was within a mile of the geographic center of the county, reasonably level and near a good source of timber. The first town lots were sold in 1845, and the town was named after General Henry Knox to commemorate his service in the American Revolutionary War.
In early 1853, the citizens of Marion County created a committee to attract railroad development to the county and to Knoxville, with members promising to buy shares in any railroad that reached town. The first contender was the Muscatine, Oskaloosa & Council Bluffs, proposing an east-west line that would pass through Knoxville. By 1875, when this line reached Knoxville, it was the Chicago, Burlington & Quincy Railroad. The second railroad to reach Knoxville was the Chicago, Rock Island & Pacific, which completed a line from Oskaloosa in 1876.
Systematic coal mining in Marion County began with the Union Coal Company's mine in Flagler, 4 miles (6.4 km) east of Knoxville in around 1874 or 1875. For several years, the Number 5 mine in Flagler was one of the most productive in Iowa, employing around 150 men and working a coal vein over 8 feet (2.5 m) thick. The Oak Hill coal company also had mines in Flagler.
Shortly after the railroad reached Knoxville, J. T. James opened a coal mine in town just 8 blocks north of the courthouse. This mine continued in operation until 1890. A second mine nearby was operated by W. A. Gamble. In the 1880s, the White Breast Fuel Company opened the Number 11 mine at Flagler. This mine operated in a coal vein that was locally up to 14 feet thick, but only locally. The mine continued operating until 1892, working in progressively thinner coal as it expanded.
