The State of Illinois (pronounced IPA: /ˌɪlɨˈnɔɪ/) is a state of the United States of America, the 21st to be admitted to the Union. Illinois is the most populous and demographically diverse[5] Midwestern
state and the fifth most populous in the nation. With Chicagoland
in the northeast, small industrial cities and great agricultural productivity in central and western Illinois, and natural resources like coal, timber, and petroleum in the south, Illinois has a broad economic base. Illinois is an important transportation hub; the Port of Chicago
connects the Great Lakes
to the Mississippi River via the Illinois River
. Illinois is often viewed as a microcosm
of the United States; an Associated Press
analysis of 21 demographic factors determined Illinois was the "most average state,"[6] while the city of Peoria
has long been a proverbial social and cultural
bellweather
.
Between 1300 and 1400 AD, the Mississippian
city of Cahokia
had a population of around 40,000, making it the largest city within the future United States until it was surpassed by Philadelphia in the 1800s. About 2,000 Native American hunters and a small number of French
villagers inhabited the Illinois area at the time of the American Revolution.[7] American settlers began arriving from Kentucky in the 1810s; they achieved statehood in 1818. The future metropolis of Chicago was founded in the 1830s on the banks of the Chicago River
, one of the only natural harbors on southern Lake Michigan
.[8] Railroads
and John Deere
's invention of the self-scouring steel plow
made central Illinois' rich prairie
into some of the world's most productive and valuable farmlands, attracting immigrant
farmers from Germany
and Sweden
. Northern Illinois provided major support for Illinoisans Abraham Lincoln and Ulysses S. Grant
during the American Civil War. By 1900, the growth of industry in northern cities and coal mining in central and southern areas attracted immigrants from Eastern
and Southern Europe
, and also made the state a major arsenal in both world war
s. In addition, large numbers of blacks migrated to Chicago from the South
, where they formed a large community
and created the city's famous jazz
and blues
cultures.

[edit] Geography
The state is named for the French
adaptation of an Algonquian language (perhaps Miami
) word apparently meaning "s/he speaks normally" (Miami ilenweewa,[9][10] Proto-Algonquian
*elen-, "ordinary" and -we·, "to speak").[11] Alternately, the name is often associated with the indigenous Illiniwek
people, a consortium
of Algonquian
tribes that thrived in the area. The name Illiniwek is frequently (incorrectly) said to mean "tribe of superior men";[12] in reality, it only means "men".[13][14][15]
The eastern border of Illinois is Lake Michigan
. Its eastern border with Indiana is all of the land west of the Wabash River
, and a north-south line above Post Vincennes
, or 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
.[16] Illinois also borders Michigan, but only via a water boundary in Lake Michigan.[17]
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
generally sits along Interstates 39
and 90
and is the state's third largest city
Southward and westward, the second major division is Central Illinois
, an area of mostly flat 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 soybean
s, 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
.[17]
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 mix of crops (including some cotton
farming in the past), more rugged topography (the southern tip is unglaciated with the remainder glaciated during the Illinoian Age
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.[17]
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 Zone
, a region of unglaciated and therefore higher and more rugged topography, occupies a small part of the state. Charles Mound
, located in this region, has the state's highest elevation above sea level
at 1,235 feet (376 m). The highest structure in Illinois is the Sears Tower
with a roof elevation of approximately Template:Convert/LoffAoffDbSoff above sea level. [Chicago elevation (580 ft) + tower height (1450) = 2030.]
The floodplain on the Mississippi River from Alton
to the Kaskaskia River
is the American Bottom
, and is the site of the ancient city of Cahokia
. It was a region of early German settlement, as well as the site of the first state capital, at Kaskaskia
which is separated from the rest of the state by the Mississippi River.[18][17]
[edit] Climate
Because of its nearly 400 mile (640 km) length and mid-continental situation, Illinois has a widely varying climate. Most of Illinois has a humid continental climate
(Koppen climate classification
Dfa) with hot, humid summers and cool to cold winters. The southernmost part of the state, from about Carbondale
southward, borders on a humid subtropical climate
(Koppen Cfa) with more moderate winters. Average yearly precipitation for Illinois varies from just over 48 inches (1,220 mm) at the southern tip to around 35 inches (890 mm) in the northern portion of the state. Normal annual snowfall exceeds 38 inches (96 cm) in Chicagoland, while the southern portion of the state normally receives less than 14 inches (35 cm).[19] The highest temperature recorded in Illinois was 117 °F (47 °C), recorded on July 14
1954
, at East St. Louis, while the lowest temperature was -36 °F (-38 °C), recorded on January 5
1999
, at Congerville
.[20][18][17]
Illinois averages around 50 days of thunderstorm
activity a year which put it somewhat above average for number of thunderstorm days for the United States. Illinois is vulnerable to tornadoes with an average of 35 occurring annually, which puts much of the state at around 5 tornadoes per Template:Convert/LoffAoffDbSoff annually.[21] The deadliest tornado on record in the nation occurred largely in Illinois. The Tri-State Tornado
of 1925 killed 695 people in three states; 613 of the victims lived in Illinois.[22]

[edit] Recreation
- See also: List of protected areas of Illinois
Illinois has numerous museums. The state of the art Abraham Lincoln Presidential Library and Museum in Springfield is the largest presidential library in the country. And numerous museums in the city of Chicago are considered some of the best in the world. These include the John G. Shedd Aquarium
, the Field Museum of Natural History
, the Art Institute of Chicago
, and the Museum of Science and Industry (Chicago)
. The Museum of Science and Industry (Chicago)
is the only building remaining from the 1893 Columbian Exposition
held in Chicago to celebrate the 400th anniversary of Columbus' discovery of the new world.
The Illinois state park
system began in 1908 with what is now Fort Massac
State Park becoming the first park in a system encompassing over 60 parks and about the same number of recreational and wildlife areas.
Areas under the protection and control of the National Park Service
include the Illinois and Michigan Canal National Heritage Corridor
near Lockport
, the Lewis and Clark National Historic Trail
, the Lincoln Home National Historic Site
in Springfield, the Mormon Pioneer National Historic Trail
, and the Trail of Tears National Historic Trail
.
[edit] History
[edit] Pre-Columbian
Cahokia
, the urban center of the pre-Columbian
Mississippian culture
, was located near present-day Collinsville, Illinois
. That civilization vanished in the 15th century for unknown reasons. The next major power in the region was the Illiniwek
Confederation, or Illini, a political alliance among several tribes. There were about 25,000 Illinois Indians in 1700, but systematic attacks and genocide by the Iroquois
reduced their numbers by 90%.[29] Members of the Potawatomi
, Miami
, Sauk
, and other tribes came in from the east and north.[17] In the American Revolution, the Illinois and Potawatomi supported the American cause.
[edit] European exploration
French
explorers Jacques Marquette
and Louis Jolliet
explored the Illinois River
in 1673. As a result of their exploration, Illinois was part of the French empire until 1763, when it passed to the British
. The small French settlements continued; a few British soldiers were posted in Illinois but there were no British or American settlers. In 1778 George Rogers Clark
claimed the Illinois Country
for Virginia
. The area was ceded by Virginia to the new United States in 1783 and became part of the Northwest Territory
.[30]
[edit] 19th century
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 after exaggerating its population totals. The new state debated slavery then rejected it, as settlers poured into southern Illinois from Kentucky.
Thanks to Nathaniel Pope
, the delegate from Illinois, Congress shifted the northern border 41 miles north to 42° 30' north, which added Template:Convert/LoffAoffDbSoff to the state, including Chicago, Galena
and the lead mining region. The capital remained at Kaskaskia, but in 1819 it was moved to Vandalia
. In the 1832 Black Hawk War
Indians who had removed to Iowa attempted to return, but were defeated by the 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. 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.[31]
By 1839 the Mormon
utopian city of Nauvoo
, located on the Mississippi River, was created and settled, and flourished. In 1844 the Mormon leader Joseph Smith
was killed in the Carthage, Illinois
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. In 1846 the Mormons had left Illinois for the West in a mass exodus.
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.[30]
With the tremendous growth of mines and factories in Illinois 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
.

[edit] American Civil War
During the American Civil War, over 250,000 Illinois men served in the Union Army
, more than any other northern state except New York
, Pennsylvania
, and Ohio
. Beginning with President 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.[32]
[edit] 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. 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 4th in U.S. oil production.
Following World War II, Argonne National Laboratory
, near Chicago, activated the first experimental nuclear power generating system in 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
.
In 1970, the state's sixth constitutional convention authored a new constitution to replace the 1870 version. It 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
