In 1887 four Chicago anarchists were executed. A fifth cheated the hangman by killing himself in prison. Three more were to spend 6 years in prison until pardoned by Governor Altgeld who said the trial that convicted them was characterised by "hysteria, packed juries and a biased judge". The state had, in the words of the prosecution put "Anarchy .. on trial" and hoped their deaths would also be the death of the anarchist idea.

The anarchists were trade union organisers and May Day became an international workers day to remember their sacrifice. They were framed on false charges of throwing a bomb at police breaking up a demonstration in Chicago. This was part of a strike demanding an 8 hour day involving 400,000 workers in Chicago that started May 1st 1886 .

This collection showcases more than 3,800 images of original manuscripts, broadsides, photographs, prints and artifacts relating to the Haymarket Affair. The violent confrontation between Chicago police and labor protesters in 1886 proved to be a pivotal setback in the struggle for American workers' rights. These materials pertain to: the May 4, 1886 meeting and bombing; to the trial, conviction and subsequent appeals of those accused of inciting the bombing; and to the execution of four of the convicted and the later pardon of the remaining defendants. Of special interest and significance are the two dozen images of three-dimensional artifacts, including contemporary Chicago Police Department paraphernalia, labor banners, and an unexploded bomb casing given to juror J. H. Brayton by Chicago Police Captain Michael Schaack. The cornerstone is the presentation, as images and searchable text, of the transcript of the 3,200 pages of proceedings from the murder trial of State of Illinois v. August Spies, et al.

The Edmonton May Week Labour Arts Festival brings together the labour movement, workers and artists to celebrate the achievements of people’s struggles for social and economic justice through visual arts, music, film, poetry and theatre.

MAYWORKS is a festival held throughout the month of May to honour and promote the many positive contributions of unions and working people in general. Inspired by events surrounding the anniversary of the 1919 Winnipeg General Strike, MAYWORKS focuses on the art produced both by artists, with their depiction of the working class life and by workers with their own interpretation of their lives and struggles.

The Dramas of Haymarket is an online project produced by the Chicago Historical Society and Northwestern University.
