Great Chicago Fire. The Great Chicago Fire was a conflagration that burned from Sunday, October 8, to early Tuesday, October 10, 1871. The fire killed up to 300 people, destroyed roughly 3.3 square miles (9 km2) of Chicago, Illinois, and left more than 100,000 residents homeless.
No one is sure how the Chicago blaze began, but one eyewitness saw the first flames leaping out of Mr. And Mrs. O'Leary's barn. Rumor, and now legend, has it that their cow kicked over an oil lamp, setting straw on fire. Mrs. O'Leary's cow may well be the most infamous cow in American history! Firefighters brought the fire under control the next day, on October 9, 1871, but only with the help of a rainstorm. It had been unusually warm and dry that year, and the city's wood buildings burned like matches until finally the rain came down.
