Haymarket affair

Article summary

The Haymarket affair was a bombing that took place at a labor demonstration on May 4, 1886, at Haymarket Square in Chicago. The rally began peacefully in support of workers striking for an eight-hour work day; it was held the day after a May 3 rally at a McCormick Harvesting Machine Company plant on the West Side of Chicago, during which police killed two strikers by opening fire at the crowd as it surged to the gate to confront strikebreakers. Many others were injured. At the Haymarket Square rally on May 4, an unknown person threw a dynamite bomb at the police as they acted to disperse the meeting, and the bomb blast and ensuing retaliatory gunfire by the police caused the deaths of seven police officers and at least four civilians; dozens of others were wounded. Eight anarchists were charged with the bombing. They were convicted of conspiracy in the internationally publicized legal proceedings. The evidence put forward in the court trial was that one of the defendants may have built the bomb but none of those on trial had thrown it, and only two of the eight were at the Haymarket at the time. Seven were sentenced to death and one to a term of 15 years in prison. Illinois governor Richard J. Oglesby commuted two of the sentences to terms of life in prison; another died by suicide in jail before his scheduled execution. The other four were hanged on November 11, 1887.…
