Illinois
The Illinois-Wabash Company was an early claimant to much of Illinois. The Illinois Territory was created on February 3, 1809, with its capital at Kaskaskia. In 1818, Illinois became the 21st U.S. state. The new state debated slavery, finally rejecting it, as settlers poured into southern Illinois from Kentucky.
Due to the efforts of Nathaniel Pope, the delegate from Illinois, Congress shifted the northern border 41 miles (66 km) north to 42° 30' north, which added 8,500 square miles (22,000 km 2 ) to the state, including Chicago, Galena and the lead mining region. The capital remained at Kaskaskia, but in 1819 was moved to Vandalia. In 1832, the Black Hawk War was fought in Illinois and current day Wisconsin between the United States and the Sauk, Fox and Kickapoo Indian tribes. The Indians withdrew to Iowa; when they attempted to return, they were defeated by U.S. militia and forced back to Iowa.
The winter of 1830–1831 is called the "Winter of the Deep Snow"; a sudden, deep snowfall blanketed the state, making travel impossible for the rest of the winter, and many travelers perished. Several severe winters followed, including the "Winter of the Sudden Freeze". On December 20, 1836, a fast-moving cold front passed through, freezing puddles in minutes and killing many travelers who could not reach shelter. The adverse weather resulted in crop failures in the northern part of the state. The southern part of the state shipped food north and this may have contributed to its name: "Little Egypt", after the Biblical story of Joseph in Egypt supplying grain to his brothers.
By 1839, the Mormon utopian city of Nauvoo, located on the Mississippi River, was created, settled, and flourished. In 1844, the Mormon leader Joseph Smith was murdered in the Carthage jail. After close to six years of rapid development, the Mormon city of Nauvoo, which rivaled Chicago as Illinois' largest city, saw a rapid decline after the Mormons left Illinois in 1846 for the West in a mass exodus.
The state has a varied history in relation to slavery and the treatment of African Americans in general. Some slave labor was used before it became a territory, but slavery was banned by the time Illinois became a state in 1818. As the southern part of the state, known as "Little Egypt", was largely settled by migrants from the South, the section was sympathetic to the South and slave labor. For a while, the section continued to allow settlers to bring slaves with them for labor, but citizens were opposed to allowing blacks as permanent residents. The Illinois Constitution of 1848 was written with a provision for exclusionary laws to be passed. In 1853, John A. Logan, later a Union general in the American Civil War, introduced such bills. Laws were passed to prohibit all African Americans, including freedmen, from settling in the state.
Chicago gained prominence as a Great Lakes port and then as an Illinois and Michigan Canal port after 1848, and as a rail hub soon afterward. By 1857, Chicago was Illinois' largest city. With the tremendous growth of mines and factories in the state in the 19th century, Illinois played an important role in the formation of labor unions in the United States. The Pullman Strike and Haymarket Riot in particular greatly influenced the development of the American labor movement. From Sunday, October 8, 1871 until Tuesday, October 10, 1871, the Great Chicago Fire burned in downtown Chicago, destroying 4 square miles (10 km 2 ).
In 1847, after lobbying by Dorothea L. Dix, Illinois became one of the first states to establish a system of state-supported treatment of mental illness and disabilities, replacing local almshouses.
Civil War
Main article: Illinois in the Civil WarDuring the American Civil War, over 250,000 Illinois men served in the Union Army, a figure surpassed by only New York, Pennsylvania, and Ohio. Beginning with President Abraham Lincoln's first call for troops and continuing throughout the war, Illinois mustered 150 infantry regiments, which were numbered from the 7th to the 156th regiments. Seventeen cavalry regiments were also gathered, as well as two light artillery regiments.
Twentieth century
In the 20th century, Illinois emerged as one of the most important states in the union, with a population of nearly 5 million bolstered by continued immigration from southern and eastern Europe, and by African-Americans from Mississippi, Louisiana, and Arkansas. By the end of the century, the population would reach 12.4 million. The Century of Progress World's Fair was held at Chicago in 1933. Oil strikes in Marion County and Crawford County lead to a boom in 1937, and, by 1939, Illinois ranked fourth in U.S. oil production.
Following World War II, Argonne National Laboratory, near Chicago, activated the first experimental nuclear power generating system in the United States in 1957. By 1960, the first privately financed nuclear plant in United States, Dresden 1, was dedicated near Morris. Chicago became an ocean port with the opening of the Saint Lawrence Seaway in 1959. The seaway and the Illinois Waterway connected Chicago to both the Mississippi River and the Atlantic Ocean. In 1960, Ray Kroc opened the first McDonald's franchise in Des Plaines (which still exists today as a museum, with a working McDonald's across the street).
In 1970, the state's sixth constitutional convention authored a new constitution to replace the 1870 version, which was ratified in December. The first Farm Aid concert was held in Champaign to benefit American farmers, in 1985. The worst upper Mississippi River flood of the century, the Great Flood of 1993, inundated many towns and thousands of acres of farmland. It also flooded many homes and streets slowing transportational services.
Geography
Main article: Geography of IllinoisThe Northeastern border of Illinois is Lake Michigan. Its eastern border with Indiana is the Wabash River and a north-south line above Post Vincennes, 87° 31′ 30″ west longitude. Its northern border with Wisconsin is fixed at 42° 30' north latitude. Its western border with Missouri and Iowa is the Mississippi River. Its southern border with Kentucky is the Ohio River. Illinois also borders Michigan, but only via a water boundary in Lake Michigan.
Though Illinois lies entirely in the Interior Plains, it has three major geographical divisions. The first is Northern Illinois, dominated by the Chicago metropolitan area, including the city of Chicago, its suburbs, and the adjoining exurban area into which the metropolis is expanding. As defined by the federal government, the Chicago metro area includes a few counties in Indiana and Wisconsin and stretches across much of northeastern Illinois. It is a cosmopolitan city, densely populated, industrialized, and settled by a wide variety of ethnic groups. The city of Rockford, the second largest metropolitan area and the state's third largest city sits along Interstates 39 and 90 some 75 miles (121 km) northwest of Chicago.
Southward and westward, the second major division is Central Illinois, an area of mostly prairie. Known as the Heart of Illinois, it is characterized by small towns and mid-sized cities. The western section (west of the Illinois River) was originally part of the Military Tract of 1812 and forms the distinctive western bulge of the state. Agriculture, particularly corn and soybeans, as well as educational institutions and manufacturing centers, figure prominently. Cities include Peoria, the third largest metropolitan area in Illinois at 370,000; Springfield, the state capital; Quincy; Decatur; Bloomington-Normal; and Champaign-Urbana. The Illinois Quad Cities, as of 2008, had a population of 377,625 and is almost at the same latitude as Chicago. They are sometimes grouped in Central Illinois due to economic, political, and cultural ties to this region. This population actually makes it the third largest metropolitan area in Illinois. However, since its area spans two states, namely Illinois and Iowa, it is not usually considered the third largest metropolitan area.
The third division is Southern Illinois, comprising the area south of U.S. Route 50, and including Little Egypt, near the juncture of the Mississippi River and Ohio River. This region can be distinguished from the other two by its warmer climate, different variety of crops (including some cotton farming in the past), more rugged topography (the southern tip is unglaciated with the remainder glaciated during the Illinoian Stage and earlier ages), as well as small-scale oil deposits and coal mining. The area is a little more populated than the central part of the state with the population centered in two areas. First, the Illinois suburbs of St. Louis comprise the second most populous metropolitan area in Illinois with nearly 600,000 inhabitants, and are known collectively as the Metro-East. The second area is Williamson County, Jackson County, Franklin County, Saline County and Perry County. It is home to around 210,000 residents and is known collectively as Metro Lakeland.
The region outside of the Chicago Metropolitan area is often described as "downstate Illinois". However, residents of central and southern Illinois view their regions as geographically and culturally distinct, and do not necessarily use this term.
In extreme northwestern Illinois, the Driftless Area, a region of unglaciated and therefore hig
