The coal strike during what year was one of the largest in the nation’s history?

It was the Anthracite Strike which took place in 1902 during the summer and into the fall.

Explanation:

In 1902, the United Mine Workers convoked a strike in the anthracite coal fields in Pennsylvania. People supported the workers, who asked for better working conditions, better payments as well as the recognition of their union.

As a result of this, schools and businesses had to close because there was no coal for heating.

Roosevelt was not concerned with this kind of affairs but he achieved to meet members of both sides and take them to a meeting in the White House. Thanks to Roosevelt's engagement an arrangement was made and the strike ended on March 1903 and the miners achieved a wage increase.
