Neither group had true equality with whites.  Both free African Americans and enslaved ones were discriminated.

Between 1870 and 1970, the southern United States lived a period where different rights were established depending on the race. Slavery was abolished and influenced by racist ideologies, a system of racial segregation was created in which Anglo-Saxon whites established their supremacy over blacks, so that inequality continued to be maintained.

After the Civil War (1861-1865) the southern states, resentful of their defeat, drafted a series of laws to discredit men of color. This phenomenon was euphemistically called "reconstruction." The process was so intense and extensive that by 1877, with the election of Rutherford Hayes as the 19th president of the United States, discrimination and racism was common in northern cities such as New York, Boston, Detroit and Chicago.

Because states could not eliminate the rights of blacks when guaranteed by the constitution, the term "segregation" was used with the concept of "Separate but Equal" (Separated but equal). The idea was that while the opportunities offered to both races were equal, segregation was legal.
