History of Chicago Timeline
(1833 - Present)Chicago's history spans from its origins as a Potawatomi settlement and fur trading post on Lake Michigan to its transformation into a major American metropolis. Incorporated as a city in 1837, Chicago grew rapidly due to its strategic location connecting the Great Lakes to the Mississippi River watershed. The city was famously destroyed by the Great Chicago Fire of 1871 but rebuilt quickly, becoming a hub for architecture, industry, immigration, and culture. Key moments include the 1893 World's Columbian Exposition, the Prohibition-era gangster era, the Civil Rights Movement, and its modern role as a global center of commerce and culture. More Less
