Cities and Towns in the United States > Illinois

Illinois


Illinois is bordered by Wisconsin in the north; Lake Michigan, Indiana, and Kentucky in the east; Kentucky and Missouri in the south; and Missouri and Iowa in the west. With a population of 12,671,821 (January 2020), Illinois is the sixth largest population, and the 25th largest land area of all U.S. states. The capital of Illinois is Springfield, but the biggest city is Chicago. Its governor is J. B. Pritzker, an American businessman, co-founder of the Pritzker Group, and a member of the Pritzker family that owns the Hyatt hotel chain.

The first Europeans to reach the area were French explorers Jacques Marquette and Louis Jolliet, who arrived in 1673. In 1717 Illinois became part of the Louisiana territory, a French colony, but in 1763 the French ceded the region to Britain. After the American Revolution, Illinois became a U.S. territory, and in 1818 it was declared the 21st state.

Because of its geographic position and its long north-south axis, Illinois has wide regional variations in temperature. Across the state, seasonal temperature variation also tends to be great, with typically cold, snowy winters and hot summers. Much of Illinois was once covered in prairie grass, earning the state its nickname. The diversified nature of its economy, strength in manufacturing, agriculture, finance, mining, transportation, government, technology, and services (including tourism) makes Illinois a microcosm of the national economy.

The state’s official snack food is popcorn, which can be served Chicago-style: with a mixture of cheese-covered and caramel-covered popcorn.

Illinois’ slogan is "the Land of Lincoln" because Abraham Lincoln lived there for 31 years. Today, visitors can see Lincoln’s home and his tomb in Springfield.
