The flag of Illinois

Illinois (/ˌɪlɪˈnɔɪ/ IL-in-OY) is a state in the Midwestern region of the United States. It borders 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 largest urban areas include Chicago and the Metro East of Greater St. Louis, as well as Peoria, Rockford, Champaign–Urbana, and Springfield, the state's capital.

Illinois has a highly diverse economy, with the global city of Chicago in the northeast, major industrial and agricultural hubs in the north and center, and natural resources such as coal, timber, and petroleum in the south. Owing to its central location and favorable geography, the state is a major transportation hub: the Port of Chicago has access to the Atlantic Ocean through the Great Lakes and Saint Lawrence Seaway and to the Gulf of Mexico from the Mississippi River via the Illinois Waterway. Chicago has been the nation's railroad hub since the 1860s, and its O'Hare International Airport has been among the world's busiest airports for decades. Illinois has long been considered a microcosm of the United States and a bellwether in American culture, exemplified by the phrase Will it play in Peoria?.

Present-day Illinois was inhabited by various indigenous cultures for thousands of years, including the advanced civilization centered in the Cahokia region. The French were the first Europeans to arrive, settling near the Mississippi and Illinois River in the 17th century in the region they called Illinois Country, as part of the sprawling colony of New France. Following U.S. independence in 1783, American settlers began arriving from Kentucky via the Ohio River, and the population grew from south to north. Illinois was 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 small settlement of Chicago became one of the fastest growing cities in the world, benefiting from its location as one of the few natural harbors in southwestern Lake Michigan. 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 and Sweden. In the mid-19th century, the Illinois and Michigan Canal and a sprawling railroad network greatly facilitated trade, commerce, and settlement, making the state a transportation hub for the nation.

Selected article

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...)
