Rioting and Bloodshed in the Streets of Chicago, 1886

Vintage engraving features a scene where a police patrol-wagon is attacked by a mob of 12,000 rioters in Chicago, Illinois in May 1886. This riot, known as the Haymarket Square Riot, began as a peaceful rally in support of workers striking for an eight-hour work day, until a bomb exploded, causing the riot. The bomb was allegedly built and exploded by anarchists. The Haymarket Affair is generally considered significant as the origin of International Workers' Day held on May 1st (May Day.)
