Respuesta :

I believe the answer is: the debate over the ratification of the fifteenth amendment

Prior to the ratification, womens and minorities in united states were not allowed to vote in the election. Due to the reconstruction,the 
state governments are not allowed to deny a person's right to vote due to that person's race,gender, or social status.

Your answer would be:

The debate over the ratification of the fifteenth amendment
