The Great Chicago Fire of 1871 destroyed about 17,500 buildings and forced over 100,000 people to flee. Over time, the disaster became central to the city's cultural identity. Author Jim Murphy details this transformation, showing how a city that was once “a city ready to burn” rebuilt itself into a symbol of resilience that Chicagoans continue to commemorate (18).

One of the most prominent tributes is the municipal flag of Chicago, adopted in 1917. The original flag included two stars, one for the Great Fire and one for the 1893 World’s Columbian Exposition; the current four-star version still preserves the fire as one of the city’s defining historical markers. Displayed on buildings, bridges, and merchandise citywide, the flag treats the fire as part of the city’s public identity and history. In professional sports, Major League Soccer’s Chicago Fire Football Club was founded on October 8, 1997, the anniversary of the fire’s beginning, using the disaster’s name as part of the club’s connection to the city’s history. Both symbols echo the spirit that Murphy captures through Alfred Sewell’s prediction that Chicago would rise “like the Phoenix, from her ashes” to become greater than before (120).

The fire's physical legacy is also preserved at its point of origin. The Robert J. Quinn Fire Academy, where Chicago trains its firefighters, stands on DeKoven Street near the site of the O’Leary barn, where the blaze began. Nationally, Fire Prevention Week is observed each October around the anniversary of the disaster, linking the tragedy to broader public safety awareness. These commemorations illustrate how an event rooted in what Murphy portrays as unsafe building practices, drought conditions, and failures in emergency response has been absorbed into Chicago’s identity as proof of the city’s capacity for reinvention.

Public perceptions of the fire also reflected tensions surrounding immigration and class in 19th-century Chicago. Murphy shows that public explanations of the disaster quickly attached blame to Catherine O’Leary, an Irish Catholic immigrant whose barn was linked to the fire’s origin. Reporters and civic leaders fixed attention on “the poor and slovenly people of De Koven Street” (31), reflecting broader anti-immigrant attitudes that already shaped perceptions of working-class Irish communities. The familiar myth of O’Leary’s cow kicking over a lantern gained wide circulation because it provided the city with a simple and memorable explanation for a disaster that involved drought conditions, dense wooden construction, strong winds, and failures within the alarm system and firefighting response.

Similar attitudes shaped criticism of the city’s firefighters, many of whom were Irish and working class. Murphy notes that accusations of a “drunken Fire Department” overlooked the exhaustion of crews who had already spent hours fighting a major blaze the previous night and were facing conditions far beyond ordinary firefighting capacity (129). These responses reveal how public memory of the fire became intertwined with ethnic prejudice and class stigma. This history helps explain why debates over blame and responsibility remain an important part of how the Great Fire is remembered.
