In short: Chicago’s municipal flag is more than a simple banner; it is a carefully curated history of the city. Featuring two pale blue stripes and four red six-pointed stars, the design encodes specific milestones and virtues. While only four stars currently fly, the debate over adding a fifth remains a local tradition.

The current design of the Chicago flag, which maintains a width-to-length ratio of 1 to 2, was the result of a 1915 municipal commission appointed by Mayor William Hale Thompson. The commission, which included figures like Charles Deering and Lawton S. Parker, tasked poet Wallace Rice with organizing a public competition. Rice’s design, which utilized six-pointed stars to distinguish the flag from the five-pointed stars found on sovereign state flags, was officially adopted to represent the city’s unique identity.

The flag’s three white horizontal areas symbolize the North, West, and South sides of the city, while the two blue bars represent Lake Michigan and the branches of the Chicago River. The four red stars each carry distinct meanings. The first commemorates the Great Chicago Fire of 1871, with its points representing transportation, labor, commerce, finance, population, and health. The second star honors the 1893 World’s Columbian Exposition, symbolizing virtues such as religion, education, and civic pride. The third star, added in 1933, marks the Century of Progress Exposition, while the fourth, added in 1939, commemorates the history of Fort Dearborn and the various political entities that have governed the region.

The potential for a fifth star has long been a subject of public discourse. Proposals have ranged from honoring the city’s contribution to the nuclear age and the founding of the Special Olympics to commemorating mayoral legacies or major sports achievements. Although the Municipal Code of Chicago technically prohibits the addition of unauthorized devices to the flag, these restrictions are largely unenforceable due to First Amendment protections. Today, the flag remains a central element of the city’s visual identity, managed under the broader Chicago Design System to ensure equitable and consistent communication for all residents.
