Which legislation end the jim crow laws that prevented african americans from voting?

don't use big vocab!
you!

Well... A big vocab was one of the ways they stopped blacks from voting. They used literacy tests that and tested them unfairly. Or, they used poll taxes, which were generally charged in periods where African Americans had a significantly lesser income than whites.

Out of many trials, Plessy v. Ferguson (1896) marked the beginning of a 58-year period where Jim Crow was largely unchallenged and condoned by the federal government. Homer Plessy, a black man who tried to board a white-only train in Louisiana (the car designated for blacks was full), claimed the Louisiana segregation laws violated both his 13th and 14th Amendment rights. Once Plessy boarded the white-only train, he was forcibly removed and jailed. The Supreme Court, by a vote of 8-1, ruled that equal rights did not mean co-mingling of the races, effectively legalizing and facilitating "separate but equal" access for blacks. Again, the lone dissenter was Justice Harlan. Plessy not only perpetuated the white supremacist beliefs of the time, but also made it possible for states to make and enforce Jim Crow laws with impunity.

Is that all any more to the question
