TheGreat Chicago Fire burned October 8 to 10, 1871, inChicago, Illinois. Chicago, with its frequent high winds and countless wooden structures, wasprone to fires even before the “Great Fire” tore through the city. However, none was so destructive as this one. It ultimatelykilled 300 people and destroyed more than 17,000 buildings.
Cause of the Fire
The fire is commonly believed to have started in a cow barn owned by Patrick andCatherine O’Leary around 9 p.m. on October 8, 1871. Although folklore states that the fire began when Catherine’s cow kicked over an oil lamp, no one really knows how the fire actually began.
Great Chicago Fire Starts
The weather had been unusually hot and dry in Chicago, and in a city predominately built with wood, that meant the fire spread quickly. Despite the efforts of the fire department, the fire raged throughout the night, even jumping the river.Firefighters tried to fight the massive flames with their fire hoses until the city’s waterworks burned, cutting off that supply of water.
The huge fire burned for about another 24 hours essentially unchecked—consuming a largeportion of the city, residential and business districts alike—until it began to burn itself out on the night of the 9th. A light rainstorm that same night helped douse the remaining flames.
Aftermath
By the 10th, when the fire was finally out, an area about 4 miles long and almost a mile wide had been burned to the ground, leaving 100,000 peoplehomeless. Help came fromcities, businesses, and individuals across the country, whodonated money and food to the beleaguered city.
Despite thedevastation caused by Chicago’s fire,reconstruction (this time using less wood) began almost immediately. Within a little more than 20 years, Chicagorose from its ashes to become a booming city able to host the 1893 World’s Fair.
