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.
They fought with direct action protests and keen political organizing such as voter registration drives and the Mississippi Freedom Democratic Party.
