History

Pre-Columbian

Cahokia, the urban center of the pre-Columbian Mississippian culture, was located near present-day Collinsville, Illinois. That civilization vanished circa 1400–1500 for unknown reasons. The next major power in the region was the Illiniwek Confederation or Illini, a political alliance among several tribes. The Illiniwek gave Illinois its name. The Illini suffered in the seventeenth century as Iroquois expansion forced them to compete with several tribes for land. The Illini were replaced in Illinois by the Potawatomi, Miami, Sauk, and other tribes.

European exploration

French explorers Jacques Marquette, S.J., and Louis Joliet 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 as a result of the French and Indian War. George Rogers Clark claimed the Illinois Country for the Commonwealth of Virginia during his military campaigns there in 1778. The area was ceded to the new United States in 1783 and became part of the Northwest Territory.

The 1800s

The Illinois-Wabash Company was an early claimant to much of Illinois. The Illinois Territory was created on February 3, 1809. In 1818, Illinois became the 21st U.S. state. Early U.S. settlement began in the south part of the state and quickly spread northward, driving out the native residents. With the 1832 Black Hawk War, the last native tribes were driven out of northern Illinois.
