Did you know that Illinois was the first state to ratify (accept) the 13th amendment to abolish (end) slavery?  Did you know that Illinois is where Abraham Lincoln spent most of his life?

Named for the Illinois Indians, Illinois is a top supplier of soybeans and corn and is also known for its production of pork and dairy products, livestock, and grains.  Chicago, one of the largest cities in the US, is a national railroad hub and has one of the busiest international airports in the country. The state is also known for its skyscrapers:  Willis Tower, which stands at 1,451 feet, and the neo-Gothic Tribune Tower.

The state’s motto, “State Sovereignty, National Union,” appears on the state flag and state seal.  This was controversial after the Civil War when national unity was especially important, so state lawmakers required that the flag and seal be twisted to put “National Unity” at the top.  Illinois has a very diverse population of over 12.5 million.

Historical Facts About Illinois

Illinois’ history dates back to 8,000 BC when Native Americans lived along the waterways of Illinois. Some of the  tribes known to have lived in Illinois include the Algonquian-speaking people of the Kickapoo, Sauk, Fox, Potawatomi, Ottawa, Ojibwa (Chippewa), Kaskaskia, Peoria, Cahokia, and Tamaroa.

The first Europeans arrived from France in 1673, but France gave up its claims to Illinois to Britain as a result of the French and Indian War.  By 1773, as a result of the resentment of British policy in the area, the number of settlers declined to about 1,000, plus a few hundred slaves. After American forces captured Kaskaskia, the site of the region’s British government, Illinois became a county of Virginia. However, Virginia later on ceded the area to the newly formed United States to form the Northwest Territory.

When the Northwest Territory was divided in 1800, Illinois became part of the Indiana Territory, then the Illinois Territory was formed in 1809 when the Indiana Territory was divided, and later became a state.

As a state, Illinois became a leader in social policy, economic progress, and cultural growth.  It created laws protecting children in the 1880’s and 1890’s and was the site of the 1893 World’s Columbian Exposition, showcasing America’s technological and scientific progress.  Chicago became the second largest city in the US by the 1880’s. The first atomic chain reaction occurred at the University of Chicago in 1942, beginning the country’s atomic age. All along, however, Illinois struggled with violence and scandals as a result of bootleg (illegal) liquor, organized crime under the notorious Al Capone, activities of the Ku Klux Klan, and coal strikes.

While the state still has higher violent crime rates, its cultural growth has continued.  Chicago has become a center for art, writing, and research. There is a rich movie-making history, and the area is known for its theater, dance, orchestra, opera, jazz, and blues.  Chicago has also become an architectural leader with its buildings becoming models for the world.

Illinois Geography Facts

Illinois is mostly flat with farmland, forests, wetlands, and rolling hills.  The northern, southern, and western parts of the state consist of plains that used to be covered with tall grasses before the land was used for farmland and cities.  The southernmost part of the state is unique in that it was not affected by glaciers and contains a large section of land known as the Shawnee National Forest.

Early settlers stripped the state of its lumber, leaving only 10 percent forest cover.  There are rolling hills in the northwestern corner of the state, including the highest point at Charles Mound, and also gently sloping hills in southern Illinois.  The soils of northern and central Illinois are excellent for farming, and there are about 900 streams flowing into the Mississippi River system.

The entire state sits on natural underground reservoirs.  Due to pollution and the decline in forest areas, the abundant wildlife that used to thrive in Illinois (i.e., bears, wolves, bison, mountain lions, elk, and porcupines) have disappeared.  Deer became extinct in 1910 but were reintroduced in 1933 and have regained their population. Coyotes, foxes, migrating waterfowl, and some species of fish can still be found in natural areas and more in urban areas.
