It also stated that they wouldn't deprive any person from freedom, life or property without the due process of law, they wouldn't violate any citizen's privilege or inmunity and should guarantee to every citizen equal protection of the laws. The 15th amendment (1870) granted African American the right to vote, prohibiting the use of race or color as a reason to deny someone their legal right to vote.
