"The Haymarket Affair" (historical event)

The Haymarket Affair was a violent confrontation that occurred on May 4, 1886, in Chicago during a labor protest advocating for workers' rights, especially an eight-hour workday. A rally at Haymarket Square turned chaotic when an unidentified person threw a bomb into police line, resulting in police open fire and several deaths. The incident led to a crackdown on labor activists, many of whom were anarchists or trade unionists. Although the specific bomber was never identified, the event galvanized the labor movement globally and highlighted tensions between workers seeking fair treatment and authorities resisting industrial unrest.
