Which labor union admitted skilled and unskilled workers , women , african american , farmers and factory workers?

To the best of my knowledge the answer is: an union founded in 1869, The Knights of Labor, is considered to be the first industrial union which admitted skilled and unskilled workers, women, and African‐Americans. This inclusive policy contributed to its growth, and the union boasted more than 700,000 members by the mid‐1880s. The program of the Knights of Labor was involved both reform ideas and specific worker demands.  It was led by Terence V. Powderly, and they welcomed unskilled, semi-skilled, and skilled workers into their ranks as well as immigrants, African Americans and women.
