Why do you think some southern states made blacks take a reading test before they could vote?

Some southern states implemented reading tests for Black voters as part of a broader strategy to disenfranchise them and maintain white supremacy. These tests were often designed to be confusing and difficult, ensuring that many Black individuals would fail, even if they were literate. This practice was a key component of Jim Crow laws, which aimed to circumvent the protections granted by the 15th Amendment and reinforce racial segregation and inequality in the electoral process.
