Black men, historically couldn't read, so literacy tests were an attempt to make it so that black people couldn't vote. Poll taxes were the same way, the white men could afford to pay the poll tax, but the black men couldn't due to their mostly low paying jobs. Lastly, if a white man couldn't read, or couldn't afford to pay the tax, they shouldn't have been allowed to vote, so in order to make it so that they could vote a "grandfather clause" was instated. This made it so that if your father had voted, you could vote. This meant that any white man could vote.
