During the mid-19th century the Chicago area was inhabited primarily by Potawatomis, who took the place of the Miami and Sauk and Fox people. The first non-native settler in Chicago, Jean Baptiste Pointe du Sable, was Haitian and arrived in the 1770s, married a Potawatomi woman, and founded the area's first trading post. In 1803, the United States Army built Fort Dearborn, which was destroyed in 1812 in the Fort Dearborn Massacre. The Ottawa, Ojibwa, and Potawatomi later ceded the land to the United States in the Treaty of St. Louis of 1816. On August 12, 1833, the Town of Chicago was organized with a population of 350, and within seven years it grew to a population of over 4,000. The City of Chicago was incorporated on March 4, 1837.

Chicago in its first century was one of the fastest growing cities in the world, heavily promoted by Yankee entrepreneurs and land speculators. It reached 1 million people by 1890.

Starting in 1848, the city became an important transportation link between the eastern and western United States with the opening of the Galena & Chicago Union Railroad, Chicago's first railway, and the Illinois and Michigan Canal, which allowed steamboats and sailing ships on the Great Lakes to connect through Chicago to the Mississippi River. With a flourishing economy that brought many new residents from rural communities and Irish American, Polish American, Swedish American, German American and numerous other immigrants, Chicago grew from a city of 299,000 to nearly 1.7 million between 1870 and 1900. The city's manufacturing and retail sectors dominated the Midwest and greatly influenced the American economy, with the Union Stock Yards dominating the meat packing trade.

After the Great Chicago Fire of 1871, Chicago experienced rapid rebuilding and growth.^[4] During Chicago's rebuilding period, the first skyscraper was constructed in 1885 using steel-skeleton construction. In 1893, Chicago hosted the World's Columbian Exposition on former marshland at the present location of Jackson Park. The Exposition drew 27.5 million visitors, and is considered among the most influential world's fairs in history.^[5] The University of Chicago was founded one year earlier in 1892 on the same location. The term "midway" for a fair or carnival referred originally to the Midway Plaisance, a strip of park land that still runs through the University of Chicago campus & connects Washington & Jackson Parks.

The city was the site of labor conflicts and unrest during this period, which included the Haymarket Riot on May 4, 1886. Concern for social problems among Chicago's lower classes led to the founding of Hull House in 1889, of which Jane Addams was a co-founder. The city also invested in many large, finely-landscaped municipal parks, which also included public sanitation facilities.

Lake Michigan, the primary source of fresh water for the city, was already highly polluted from population growth and the rapidly growing industries in and around Chicago. The city responded by embarking on several large public works projects, including a large excavation project which built tunnels below Lake Michigan to newly built water cribs which were two miles (3 km) off the lakeshore. However, the cribs failed to bring enough clean water, as spring rains would wash the polluted water from the Chicago River into them. Beginning in 1855, Chicago constructed the first comprehensive sewer system in the U.S. In 1900, the problem of sewage was solved by reversing the direction of the river's flow with the construction of the Chicago Sanitary and Ship Canal leading to the Illinois River.

The 1920s brought international notoriety to Chicago as gangsters such as Al Capone battled each other and the law during the Prohibition era. Nevertheless, the 1920s also saw a large increase in Chicago industry as well as the first arrivals of the Great Migration that would lead thousands of mostly Southern blacks to Chicago and other Northern cities. On December 2, 1942, the world's first controlled nuclear reaction was conducted at the University of Chicago as part of the top secret Manhattan Project.
