The Haymarket Affair was a violent confrontation that occurred on May 4, 1886, in Chicago, Illinois, during a labor protest advocating for an eight-hour workday. The event began as a peaceful rally in support of striking workers but escalated when a bomb was thrown at police, leading to chaos and the deaths of several police officers and civilians. This incident became a pivotal moment in labor history, highlighting the tensions between labor movements and law enforcement during the Gilded Age.
