On pages 334-336 of The Devil in the White City by Erik Larson, what historical reference can be found?
In an answer to a previous question of yours, I mentioned the major strike that would take place in 1894 in the town of Pullman. That strike is the major historical reference on these pages.
On these pages, we are told about the 1894 Pullman strike. We are told about how it started in Pullman and then spread. We are told about how much damage was done and about how the army was called out to help quell the strike. This is rather typical of labor relations during this time. There were many violent strikes in the last few decades of the 19th century as unions tried to organize and companies tried to destroy them. The government was typically very much in favor of the businesses and governmental power was often used to put down strikes. The major historical reference in these pages is to the Pullman strike which is a good example of the general atmosphere between unions, employers, and the government during this time.
