Why was the 15th amendment necessary following the addition of the 14th Amendment?

Answer 1

The 14th and 15th Amendment were needed to cement the African American's place as citizens in society. The 13th Amendment outlawed slavery, but people in the South were still treating blacks horribly and not treating them like citizens.

Answer 2

Because:

the 13th Amendment abolished the slavery, the 14th was effectively a Bill of Rights, guaranteeing the new black citizens their political and legal equality, the 15th stated in unambiguous terms that citizens' Rights had not to be limited by "race, color or previous condition of servitude".

Answer 3

Before the Fourteenth Amendment, state and local governments were not subject to the Bill of Rights. There was nothing stopping the local governments from violating the constitution.

The fourteenth amendment extended the Bill of Rights (and the constitution) to restrict the local governments from violating a citizen's civil rights.

Answer 4

The Fourteenth Amendment was needed because it was made to protect the rights of the newly freed slaves.
