Robert Paul Prager (February 28, 1888 – April 5, 1918) was a German immigrant who was lynched in the United States during World War I as a result of anti-German sentiment. He had worked as a baker in southern Illinois and then as a laborer in a coal mine, settling in Collinsville, a center of mining. At a time of rising anti-German sentiment, he was rejected for membership in the Maryville, Illinois local of the United Mine Workers of America. Afterward he angered area mine workers by posting copies of his letter around town that complained of his rejection and criticized the local president. A mob of 200 to 300 men forced Prager from his home in Collinsville, making him walk barefoot and wrapped in an American flag along Main Street, where they beat and harassed him. The police took him into custody, but the mob gained control again, taking him from the Collinsville City Hall and accusing Mayor John H. Siegel of being pro-German. Failing to find tar in order to tar and feather Prager, as the workers had done to other victims, leaders of the mob used a rope and hanged him to death at a prominent bluff outside town. Eleven men were tried for Prager's murder but all were acquitted. Rumors were that Prager held socialist beliefs, which were considered suspect at the time. Men in the mob claimed he was planning to blow up the coal mine, but there was no evidence against him and he had not been charged with any crime. Biography Robert Paul Prager was born in Dresden, Germany on February 28, 1888. He emigrated to the United States in 1905, at the age of 17. First working as an itinerant baker, he was sentenced to a year in an Indiana reformatory for theft. When the United States declared war on Germany on April 6, 1917, Prager was living in St. Louis, Missouri. Prager showed strong patriotism for his adopted country. He took out his first citizenship papers the day after Wilson's war speech on April 2, in order to start the naturalization process. He registered for the draft and tried to enlist in the US Navy. (Aliens were promised citizenship if they successfully served in the armed forces.) Prager continuously displayed an American flag from his window. When his St. Louis landlord objected, Prager reported him to the police. Prager was rejected
