Chicago, Illinois is a major city on the southwestern shore of Lake Michigan in the Midwestern United States. Founded in 1833 at the mouth of the Chicago River, it rapidly developed into a transportation and commercial hub linking the Great Lakes to the Mississippi River watershed and the interior of North America.

History
The area that became Chicago was inhabited by Native American peoples including the Potawatomi, Miami, and Illinois Confederation before European contact through explorers linked to the Northwest Territory era. Following treaties such as the Treaty of Detroit (1807) and later land cessions, settlers from places like New York and Massachusetts established a trading post and fort, leading to incorporation as a city in 1837 during the era of Canal Age infrastructure projects like the Illinois and Michigan Canal. The arrival of railroads including the Galena and Chicago Union Railroad and the Illinois Central Railroad tied Chicago to the national network, fueling growth that culminated in the rebuilding after the Great Chicago Fire of 1871 and the subsequent emergence of the Chicago School and architects such as Daniel Burnham, Louis Sullivan, William Le Baron Jenney, and firms like Skidmore, Owings & Merrill. The city hosted the World's Columbian Exposition of 1893 and later the Century of Progress World's Fair in 1933–34, events showcasing advances promoted by figures connected to Pullman and industrialists like Marshall Field.

Chicago's 20th-century politics featured the campaigns of Richard J. Daley and Jane Byrne, machine politics, and reform movements visible in contests involving Barack Obama and later mayors. Neighborhood transformations were shaped by migration waves including the Great Migration, the arrival of communities from Poland, Ireland, Italy, Mexico, and the role of institutions like Hull House founded by Jane Addams.
