The concept of "Separate But Equal" was a legal doctrine in the United States that allowed for racial segregation as long as facilities and opportunities were deemed to be equal for both white and Black individuals. This doctrine was established by the Supreme Court in the landmark case Plessy v. Ferguson in 1896.

Under the "Separate But Equal" doctrine, Black Americans were subjected to discriminatory laws and policies that enforced segregation in schools, public transportation, housing, and other areas of society. Despite the idea that facilities were supposed to be equal, in reality, Black individuals often received inferior resources and services compared to their white counterparts.

The "Separate But Equal" doctrine was upheld for decades and was used to justify and maintain racial segregation in the United States. It wasn't until the Supreme Court's decision in Brown v. Board of Education in 1954 that the concept was struck down, ruling that separate educational facilities were inherently unequal and a violation of the 14th Amendment's Equal Protection Clause. This decision marked a significant turning point in the Civil Rights Movement and ultimately led to the dismantling of segregation laws in the U.S.
