Final answer:
Order was finally restored by the intervention of law enforcement and military forces in various instances of strikes and labor unrest throughout history.
Step-by-step explanation:
Order was finally restored by the intervention of law enforcement and military forces. In several instances, state militias or federal troops were called in to protect property and disperse crowds. For example, in the railroad strike of 1877, President Hayes sent federal troops into major cities to restore order. In the Memorial Day Massacre of 1937, Chicago police fired upon a crowd of striking workers, resulting in deaths and injuries. These incidents of violence and the presence of law enforcement eventually led to the end of the strikes and the reestablishment of order.
