Book excerpt: Southwestern Illinois experienced a plethora of violence during the nineteenth and twentieth centuries. Settlers and Native Americans clashed at the Wood River Settlement, while Abraham Lincoln dueled on a Mississippi River island. Racial strife led to the lynching of a Black schoolteacher in Belleville in 1903 and a deadly riot in East St. Louis fourteen years later. Benbow City was a latter-day Wild West town of saloons, gambling dens and brothels, and Pere Marquette State Park screened a cache of Nike missiles. From the birthplace of Martin Luther King Jr.'s killer to the mystery surrounding Jean Lafitte's grave, John Dunphy examines the bloody ledger of southwestern Illinois.
