A new set of laws were put into place to prevent black voters from voting. Democrats did this because majority of black people voted republican, and racist democratic party leaders put those laws into place to completely root out the republican party. Hope this Helped
Fredrick Douglass was a black male who spoke up for the rights of black people and the rights of women. He was extremely important to the cause of black peoples rights. I think he is an important historical contributor knowing that he did so much for black rights and even womens rights.
