Answer:
Making it illegal to discriminate against a person because of race.
Step-by-step explanation:
The 14th Amendment was enacted after the 13th Amendment which had prohibited slavery. So, before the 14th Amendment was passed, African Americans were not regarded as slaves, but they weren't also seen as citizens nor individual with rights.
The 14th Amendment, which gave citizenship to people born or naturalized in the U.S., and granted them the right to due process and equal protection under the laws, aimed to make illegal to discriminate or to deprive a person of the rights of life, property, and liberty because of race or any other characteristic.
