Haymarket Riot (Missing)

On May 4, 1886, hundreds of workers gathered here to protest police action of the previous day against strikers engaged in a nationwide campaign for an eight-hour workday. Radicals addressed the crowd. When policeman attempted to disperse the rally, someone threw a bomb. The bomb and ensuing pistol shots killed seven policeman and four other persons. Although no evidence linked the radicals to the bomb, eight of them were convicted and four hanged. Three were later pardoned. The Strike collapsed after the tragedy.
