Explanation:

Great Railroad Strike of 1877, was a result of reduction in wage of workers on Railroad work, which was caused by prolonged economic depression after the panic of 1873.

Announced by the Baltimore and Ohio (B&O), the railroad companies had taken advantage of the economic situation, with the determination to break the trade unions that had been formed by the workers before and after the American Civil War.

At the height of the struggle, the strikes was later subdued, for various reasons amongst which are:

1. The federal army did not break, by following order and staying together in the face of the militia. While the militas lacked effective leadership and coordination.

2. Despite the fears of the industrialists and the government, the workers lack organization amd methodical approach but rather spontaneous outbursts.

Hence, the moment their vituperations had run its course, so too did the revolts.

3. At some point, some of the workers, who lacked organized bargaining power, returned to work
