Answer:
Black codes denied the blacks the rights to testify against whites, to serve on juries or in state militias, vote.
Explanation:
The Black Codes, sometimes called Black Laws, were laws governing the conduct of African Americans (free blacks). The best known of them were passed in 1865 and 1866 by Southern states, after the American Civil War, in order to restrict African Americans' freedom, and to compel them to work for low wages.
Immediately after the Civil War ended, Southern states enacted "black codes" that allowed African Americans certain rights, such as legalized marriage, ownership of property, and limited access to the courts, but denied them the rights to testify against whites, to serve on juries or in state militias, vote.
Even as former slaves fought to assert their independence and gain economic autonomy during the earliest years of Reconstruction, white landowners acted to control the labor force through a system similar to the one that had existed during slavery.

The Knights of labor was the largest and one of the most important American labor organizations of the 1880s. It was founded on the 28th day of December in year 1869 by Uriah Stephens. They promoted the producers ethic of republicanism and demanded the eight-hour day, rejected socialism and anarchism and encouraged the social and cultural uplift of the workingman. In 1880, the organization reached 28,000 members and even gained more members to 100,000 in 1884. But in 1893, the knights of labor declines its membership because of public pressure, power vested in reformist factions, and employers' unwillingness to arbitrate.
