Harrisburg () is a city in and the county seat of Saline County, Illinois, United States. It is located about 55 miles (88.51392 km) southwest of Evansville, Indiana, and southeast of St. Louis, Missouri. Its 2020 population was 8,219, and the surrounding Harrisburg Township had a population of 10,037, including the city residents. Harrisburg is included in the Illinois–Indiana–Kentucky tri-state area and is the principal city in the Harrisburg micropolitan statistical area with a combined population of 24,913.

Located at the concurrency of U.S. Route 45, Illinois Route 13, Illinois Route 145, and Illinois Route 34, Harrisburg is known as the "Gateway to the Shawnee National Forest", and is also known for the Ohio River flood of 1937, the old Crenshaw House (also known as the Old Slave House), the Tuttle Bottoms Monster, prohibition-era gangster Charlie Birger, and the 2012 EF4 tornado. A Cairo and Vincennes Railroad boomtown, the city was one of the leading bituminous coal-mining distribution hubs of the American Midwest between 1900 and 1937.

At its peak, Harrisburg's population reached 16,000 by the early 1930s. The city had one of the largest downtown districts in Southern Illinois. The city was the 20th-most populated city in Illinois outside the Chicago metropolitan area and the most-populous city in Southern Illinois outside the Metro East in 1930. However, the city has seen an economic decline due to the decreased demand for high-sulfur coal, the removal of the New York Central railroad, and tributary lowlands leaving much area around the city unfit for growth due to flood risks.

History

Pioneer and native coexistence At the beginning of recorded American history, the Harrisburg area was inhabited by several Algonquian tribes, including the Shawnee and Piankashaw, who lived in the dense inland forests. Prior to the arrival of European settlers, the Piankashaw tribe was driven out by the more aggressive Shawnee. European settlement in Illinois began with the French from 1690 and reached its peak about 1750, mainly along the Mississippi River. American settlers arrived in 1790. The French came as merchants and missionaries, with farming supplementing the need for trade. The result had benefited both the settlers and the Native Americans. The American migration, however, followed treaties which resulted in land being distributed through American Law, ignoring previous indigenous rights. Encroachment ensued and caused hard feelings between the Native Americans and the settlers who moved into the interior and along migration routes. Many of the Indians allied themselves with the British to resist, though trade with the Americans was an important reason why the Native Americans remained largely peaceful.

The town of Harrisburg was platted a few miles south of the junction of the Goshen and Shawneetown–Kaskaskia Trail, two of the first pioneer trade routes in the state. Prior to the War of 1812, most of the population of today's Saline County lived in cabins clustered around blockhouses to protect against Indian attack and dangerous wildlife such as cougars and bears. Permanent settlements in the forested area were inevitable with the influx of more settlers, and the first land entry was made in 1814 by John Wren and Hankerson Rude. By 1840 the settlers outnumbered the Native Americans, and most of the black bear population of the county had been killed off by 1845.

Founding Harrisburg was plotted shortly after Saline County was established in 1847 from part of Gallatin County. The city was named for James Alexander Harris, who had built a farmhouse and planted a corn field in a clearing in the area of the current city square around 1820.

Harris along with John Pankey, James P. Yandell, and John X. Cain, donated land for the first additions of the town to a special committee at Liberty Baptist Church in 1852, after complaints that the county seat should be centralized in the county. The county seat then was in Raleigh. The county's two main population centers were divided by the Saline River and of thicket. There were no roads in the county and many residents from the areas of Carrier Mills and Stonefort became lost when traveling to the northern settlements of Raleigh, Galatia, and Eldorado. The designated town plat was considered due to its aesthetic properties, a sandstone bluff overlooking the Saline River valley called "Crusoe's Island". Although it was heavily timbered with oak and hickory with an impenetrable hazel underbrush, the site was at the geographical center of the county. A major legal battle took place within the county government because of voter fraud accusations by the people of Raleigh. Nevertheless, Harrisburg was plotted as a village on in 1853 and became the county seat in 1859.

Industrial origins

Between 1860 and 1865 southern cotton became unavailable during the Civil War, Harrisburg was one of the few cities in the Upland South during this time to have woolen mills, making the town an industrial asset early on to Southern Illinois. Several planing mills and flour mills also dotted the city. The Cairo and Vincennes Railroad was completed in 1872 by Ambrose Burnside, and American Civil War, Union Army, brigadier general Green Berry Raum, who was living in Harrisburg at that time.

Robert King, an early proprietor, opened a brick and tile factory at the southern terminus of Main Street in 1896 with the capacity of carrying out 15,000 bricks every 10 hours. Harrisburg also saw the opening of several saw mills. The Snellbaker and Company Saw Mill and Lumber Yard opened in 1895, as well did J.B. Ford Harrisburg Planing Mill the same year. The mill had the capacity of producing of lumber every 10 hours. The Barnes Lumber Company in Harrisburg started as a sawmill operation in 1899. Since 1904 it has retailed a complete line of lumber and building materials and is the oldest, currently active mill in the city.

The Woolcott Milling Company, operated by J.H. Woolcott and J.C. Wilson built a flour mill in 1874, on the now defunct south Woolcott Street, with rail spur, behind the current Parker Plaza, that had 23 grain elevators and the capacity of carrying out 200 barrels of flour in a 24-hour period and up to 400 by 1907, with a new tower. The exchange market was located in Carrier Mills. Located on Commercial Street across the tracks from the train depot, The Southern Illinois Milling & Elevator Company was incorporated on July 29, 1891, by Philip H. Eisenmayer, with a capital stock of $50,000. The company had two elevators, erected at a cost of $125,000, one of which had a capacity of and the other a capacity of 100,000 bushels. Their milling capacity was six hundred barrels per day. Twenty-five men were employed in the operations of the mill and elevators, in addition to a force of from six to eight men regularly employed in the cooperage department.

During the Reconstruction Era, when economic conditions made impractical the growing of cotton, lumbering and tobacco growing (which pioneers found profitable commercially), grain farming by crop rotation, dairying, reforestation, merchandising and manufacturing, and Coal mining especially, began to occupy the city. In 1889, with a population of 1,500, Harrisburg became a city, with an aldermanic form of government. It adopted the commission form in 1915. Despite these early industrial advantages over other cities in the region, the Sanborn Map Company still referred to the water facilities and road conditions within the city limits, "Not good, and not paved" up to 1900.

Coal and rail era

First slope mine operations began in 1854 southeast of Harrisburg. During the early years, the coal was transported by wagon to local homes and businesses for heating. Coal Mining became an important industry for the post-Antebellum, now Gilded Age city. The Cairo and Vincennes Railroad was completed in 1872 and provided transportation for coal and the miners who tired away underground. After a series of corporate transactions brought the Cairo and Vincennes Railroad into the hands of the Cleveland, Cincinnati, Chicago & St. Louis Railway around 1890, with Illinois state representative Charles P Skaggs as mayor, Harrisburg evolved into one of the leading coal-mining centers of the Midwest. Harrisburg was a strategic spot on the railroad route with a large hump yard, making it the focal point for the most productive coal field operations. Some of the most profitable coal companies that operated around Harrisburg were Big Creek Coal, Harrisburg Coal and O'Gara Coal. Each one with their own sizable rail yards. O'gara was a Progressive Era coal company owned by Thomas J. O'gara of Chicago. He purchased and annexed 23 privately owned mines in the Harrisburg coal field which equaled of land. The Company based its headquarters in Harrisburg in 1905. O'gara only owned 12 operating mines, all in Saline County, but they had an annual output of 7,000,000 tons. 6,000 men were employed in a field capacity and the pay roll disbursement was $150,000 per month. The company paid $10,000 monthly royalty. H. Thomas was the company's general manager of mines, Ed Ghent its chief engineer and D. B. McGehee the assistant general manager.

By 1905, several small slope mines and 15 shaft mines operated in the county. Most were along the railroad line. Large numbers of immigrants from England, Wales, and eastern Europe, looking for work, detrained at the Harrisburg Train Depot; crowding around quickly expanding mining villages directly outside the city, such as Muddy, Wasson, Harco and Ledford. The city's population quickly expanded from 5,000 to 10,000 in a few years. By 1906, the Big four/CCC&STL Railroad became the New York Central, and Saline County was producing more than 500,000 tons of coal annually with more than 5000 miners at work. In 1915 the Ringling Brothers Circus made an appearance in Harrisburg.DeNeal, Gary, interview (2003). "The Legend of Charlie Birger". WSIU-TV. In 1913, the Southern Illinois Railway and Power Company operated an interurban trolley line, that ran from downtown Eldorado, into Muddy, Wasson, Beulah Heights, through downtown Harrisburg, Dorrisville, Ledford and into downtown Carrier Mills, all of which had larger residential areas than present. In 1917 there were plans to extend the line westward to Marion and Carbondale to connect to the Coal Belt Co. line, and then run it towards St. Louis. The trolley wire through the county was high. It was an off branch of the Cairo and Vincennes Railroad. The corporation erected the first electrical generating plant in Muddy, Illinois.

The Central Illinois Public Service Company purchased the Muddy Power Station in 1916. It had a generating capacity of 7,500 kilowatts. After removing an original 2,500-kilowatt unit, the company added two 5,000-kilowatt turbine-generators and one 10,000 kilowatt unit, bringing the stations total capacity to 25,000 kilowatts in 1922. Electricity generated at the station was distributed over 66-kv, double circuit steel tower transmission lines extending to West Frankfort to the west, the Ohio River to the east, and Olney to the north. The plant had two impounding reservoirs which covered and held 320 million gallons of water.
