Four of the 'Chicago martyrs' were executed in Illinois.
August Spies, Albert Parsons, Adolph Fischer and George Engel were executed for allegedly throwing a bomb at police during a demonstration demanding the 8 hour day.
Spies last words were:
"The time will come when our silence will be more powerful than the voices you strangle today."
Six years later all original eight defendants were declared innocent, a 'reprieve' that came too late for Spies, Parsons, Fischer and Engel, and also Louis Lingg, who had cheated the hangman by poisoning himself.
