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.

Carya illinoinensis, commonly called the pecan, is a species of hickory native to Mexico and the south central and southeastern United States. The pecan tree is a large deciduous tree, growing to 20–40 m (66–131 ft) in height. A pecan, like the fruit of all other members of the hickory genus, is not truly a nut, but is technically a drupe, a fruit with a single stone or pit surrounded by a husk. The seeds of the pecan are edible with a rich, buttery flavor.
Before European settlement, pecans were widely consumed and traded by Native Americans. They can provide two to five times more calories per unit weight than wild game and require no preparation. As a wild forage, the fruit of the previous growing season is commonly still edible when found on the ground. Thomas Jefferson planted Carya illinoinensis, known as "Illinois nuts", in his nut orchard at Monticello in Virginia. George Washington reported in his journal that Jefferson had given him "Illinois nuts", which he then grew at Mount Vernon. (Read more...)

Designed by architects Cochrane and Garnsey, the dome's interior features a plaster frieze painted to resemble bronze and illustrating scenes from Illinois history. Stained glass windows, including a stained glass replica of the State Seal, appear in the oculus. Ground was first broken for the new capitol on March 11, 1869, and it was completed twenty years later. Photo credit: Daniel Schwen (from Portal:Illinois/Selected picture)
