Banditti of The Prairie

The Banditti of the Prairie also, known as "The Prairie Bandits," "Pirates of the Prairie," "Prairie Pirates," or simply "The Banditti," in the U.S. state of Illinois, were a group of loose-knit outlaw gangs during the early-mid-19th century. Though bands of roving criminals were common in many parts of Illinois, the counties of Lee, DeKalb, Ogle, and Winnebago were especially affected by them. In the year 1841, the escalating pattern of house burglary, horse and cattle theft, stagecoach and highway robbery, counterfeiting, and murder associated with the Banditti had come to a head in Ogle County. As the crimes continued, local citizens formed bands of vigilantes known as Regulators. The clash between the Banditti and the Regulators in Ogle County resulted in a lynching and decreased Banditti activity within the county.

Banditti and Regulator activity continued well after the lynching that occurred in 1841. Crimes continued, committed by both sides, across northern/central Illinois. The Banditti were involved in other notable events as well, including the 1845 torture-murder of merchant, Colonel George Davenport, the namesake of Davenport, Iowa. Edward Bonney, an amateur detective who hunted down and brought to justice the killers, wrote of his exploits and alibi, which were recounted in his book, Banditti of the Prairies, or the Murderer's Doom!!: A Tale of the Mississippi Valley, published in Chicago in 1850. The outlaw gangs also continued to be active in Lee and Winnebago counties following the events in Oregon.
