This union was more commonly known as the Knights of Labor and began around 1870 in the Philadelphia, Pennsylvania area. The main problem with the Knights of Labor was its secrecy. The members kept very private their affiliation and goals of the Knights of Labor. Because both miners and operators could become members, there was no commonality to unite the members. Also, the union did not see strikes as a means to attain rights. To many people of the time, a strike was the only way that they believed they would be heard.
