On Tuesday May 4, 1886, workers striking for an eight-hour day gathered at Haymarket Square in Chicago. A bomb went off, seven cops were killed and seven anarchists were sentenced to death. A combination of a partisan judge and a lack of credible evidence led to pardons for several of the anarchists by Illinois Governor John Altgeld on June 23, 1893.
The Haymarket Martyr’s Monument was dedicated in 1893. It stands in Forest Home Cemetery in Forest Park, IL. Pay a visit on Labor Day.
