What was the purpose of the knights of labor? ?

They were a union who wanted to educate the situation of labor.

Explanation:

At the end of the 19th century, the Knights of Labor was a labor federation that advocated improving the situation of workers, that fought for an eight-hour workday and encouraged the ethics of the Republican producers.

They acted like a union at times, representing workers, but those activities were not fully organized.
