I believe you are referring to what happened to African Americans during the reconstruction of the south, when they were freed from slavery.
In that period, laws were established that prohibited African-Americans from being victims of discrimination and forced labor, although this still happened in society, especially episodes of discrimination. In addition, Africans have gained the right to vote, to be political representatives and to hold public office, as a reflection of their citizenship that was guaranteed through emancipation. Blacks could also participate in commerce, attend schools and own homes.
