1896 – The U.S. Supreme court upheld the “separate but equal” policy in the Plessy vs. Ferguson decision. The ruling was overturned 58 years later with Brown vs. Board of Education.

Plessy v. Ferguson was important because it provided a legal justification for racial segregation. In the now-infamous ruling, the Supreme Court held that separate facilities for different races were acceptable so long as they were equal. This “separate but equal” principle would remain the law of the land for over half a century.
