Question

Quizplus · Accepted Answer

The Knights of Labor were hurt irrevocably by the Haymarket Square protest. The protest, which occurred in Chicago in 1886, led to violent clashes between police and labor activists, and several people were killed. Although the Knights of Labor were not directly involved in the protest, they were associated with the labor movement and suffered a significant loss of public support as a result. The incident also prompted a backlash against the labor movement, which led to the decline of the Knights of Labor and the rise of more radical groups like the Industrial Workers of the World.
