Great Chicago Fire

The Great Chicago Fire burned in Chicago, Illinois, United States, during October 8–10, 1871. The fire killed approximately 300 people, destroyed 17,000 structures across roughly 3.3 square miles (9 km2), and left more than 100,000 residents homeless. The fire began in a neighborhood southwest of the city center. A long period of hot, dry, windy conditions, and the wooden construction prevalent in the city, led to the conflagration spreading quickly. The fire leapt the south branch of the Chicago River and destroyed much of central Chicago and then crossed the main stem of the river, consuming the Near North Side. Help flowed to the city after the fire. The city government improved building codes to stop the rapid spread of future fires and rebuilt rapidly to those higher standards. A donation from the United Kingdom spurred the establishment of the Chicago Public Library.
