Quote from : Inhuman Bondage: The Rise and Fall of Slavery in the New World Book

A final word should be said concerning the status of free blacks. Before the American Revolution this status had been ambiguous, and the number of free blacks was insignificant. <...> A rash of new laws, similar to the later Black Codes of Reconstruction, reduced free blacks almost to the status of slaves without masters. The new laws regulated their freedom of movement, forbade them to associate with slaves, subjected them to surveillance and discipline by whites, denied them the legal right to testify in court against whites, required them to work at approved jobs, and threatened them with penal labor if not actual reenslavement.
