Great Chicago Fire begins. On this day in 1871, flames spark in the Chicago barn of Patrick and Catherine OâLeary, igniting a two-day blaze that kills between 200 and 300 people, destroys 17,450 buildings, leaves 100,000 homeless and causes an estimated $200 million (in 1871 dollars; $3 billion in 2007 dollars) in damages.
