Step 1 : Introduction to the question "Which animal is often blamed for starting the Great Chicago Fire of 1871?"
In all of history, no cow is more infamous than Mrs. O'Leary's. On this day in 1871, the Great Chicago Fire began when a fire broke out in the barn behind the home of Patrick and Catherine O'Leary. Legend has it, their cow kicked over a kerosene lamp during milking, setting fire to the O'Leary barn. At least 300 people were dead, 17,450 buildings were destroyed, and 100,000 people were homeless. The fire was one of the most spectacular events of the nineteenth century, and it is recognized as a major milestone in the city's history.
