One of the most unjust decisions by the U.S. Supreme Court in American history occurred in 1896, Plessy V. Ferguson, upholding segregation or affirming “separate but equal” public facilities by a 7-1 white supremacist vote of the High Court, and causing the spread of Jim Crow laws discriminating against African Americans. It was a shameful decision. It remained the law of the land until 1954, when the Supreme Court ruled that separate schools for African Americans were inherently unequal. Then, finally, in 1964, Congress passed the Civil Rights Act outlawing segregation in public facilities. That law did not fully take effect in the American South until the 1970s, after quite a lot of resistance.
The one lone dissenter in Plessy v. Ferguson was Justice John Marshall Harlan from Kentucky.
Six of the seven justices voting in favor of the fraud of “separate but equal” had actually supported the North in the Civil War, so their vote was simply indicative of the pervasive racism in American society before the Civil Rights Act of 1964 passed.
