Illinois (/ˌɪlɪˈnɔɪ/ ^ⓘ IL-ih-NOY) is a state in the Midwestern region of the United States. It borders on Lake Michigan to its northeast, the Mississippi River to its west, and the Wabash and Ohio rivers to its south. Of the fifty U.S. states, Illinois has the fifth-largest gross domestic product (GDP), the sixth-largest population, and the 25th-most land area. Its capital city is Springfield in the center of the state, and the state's largest city is Chicago in the northeast.

Present-day Illinois was inhabited by Indigenous cultures for thousands of years. The French were the first Europeans to arrive, settling near the Mississippi and Illinois rivers in the 17th century Illinois Country, as part of their sprawling colony of New France. A century later, the revolutionary war Illinois campaign prefigured American involvement in the region. Following U.S. independence in 1783, which made the Mississippi River the national boundary, American settlers began arriving from Kentucky via the Ohio River. Illinois was soon part of the United States' oldest territory, the Northwest Territory, and in 1818 it achieved statehood. The Erie Canal brought increased commercial activity in the Great Lakes, and the invention of the self-scouring steel plow by Illinoisan John Deere turned the state's rich prairie into some of the world's most productive and valuable farmland, attracting immigrant farmers from Germany, Sweden and elsewhere.

In the mid-19th century, the Illinois and Michigan Canal and a sprawling railroad network facilitated trade, commerce, and settlement, making the state a transportation hub for the nation, especially in Chicago, which became the world's fastest growing city by the late 19th century. By 1900, the growth of industrial jobs in the northern cities and coal mining in the central and southern areas attracted immigrants from Eastern and Southern Europe. Illinois became one of America's most industrialized states and remains a major manufacturing center. The Great Migration from the South established a large Black community, particularly in Chicago, which became a leading cultural, economic, and population center; the Chicago metropolitan area holds about 65% of the state's 12.8 million residents.

Harrisburg is the county seat of Saline County, Illinois, United States. It is located about 57 miles (92 km) southwest of Evansville, Indiana, 111 miles (179 km) southeast of St. Louis, Missouri. The 2010 population was 9,017, and the surrounding Harrisburg Township had a population of 10,790, including the city residents.

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 was made infamous 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. (Read more...)

Selected biography

Paul Cornell (August 5, 1822 – March 3, 1904) was an American lawyer and Chicago real estate speculator who founded the Hyde Park Township that included most of what are now known as the south and far southeast sides of Chicago, Illinois. He turned the south side Lake Michigan lakefront area, especially the Hyde Park community area and neighboring Kenwood and Woodlawn neighborhoods, into a resort community that had its heyday from the 1850s through the early 20th century. He was also an urban planner who paved the way for and preserved many of the parks that are now in the Chicago Park District. Additionally, he was a successful entrepreneur with interests in manufacturing, cemeteries, and hotels. His modern legacy includes several large parks now in the Chicago Park District: Jackson Park, Washington Park, Midway Plaisance and Harold Washington Park. (Read more...)
