Early labor federation, Knights of Labor

The Seal of the Knights of Labor
Abbreviation K of L
Founded	December 28,  1869
Founders Uriah Smith Stephens, James L. Wright, and others
Dissolved 1949
Purpose	U.S. labor federation

The Knights of Labor helped to bring together many different types of people from all different walks of life; for example Catholic and Protestant Irish-born workers. The KOL appealed to them because they worked very closely with the Irish Land League. The Knights had a mixed record on inclusiveness and exclusiveness. They accepted women and blacks (after 1878) and their employers as members, and advocating the admission of blacks into local assemblies. However, the organization tolerated the segregation of assemblies in the South. Bankers, doctors, lawyers, stockholders, and liquor manufacturers were excluded because they were considered unproductive members of society.
