The Great Chicago Fire of 1871 was a massive conflagration that burnt for three days, killed up to 300 people and left 100,000 residents homeless. The fire started at about 9:00 p.m. on October 8, in or around a small barn belonging to the O'Leary family that bordered the alley behind 137 DeKoven Street. The shed next to the barn was the first building to be consumed by the fire, but city officials never determined the exact cause of the blaze. There has, however, been much speculation over the years. The most popular tale blames Mrs. O'Leary's cow, who allegedly knocked over a lantern; others state that a group of men were gambling inside the barn and knocked over a lantern. Still other speculation suggests that the blaze was related to other fires in the Midwest that day.
The circular medal measures 69.9mm in diameter and was struck in bronze by the Medalcraft Mint of Green Bay, Wisconsin. The mintage was limited to 100 pieces.
