The doctrine that supported racial segregation of blacks and whites by saying that "separate but equal" is known as the “segregation” doctrine.
What is the doctrine of separate but equal?
The segregation doctrine gave constitutional sanction to state laws (unofficially known as Jim Crow laws) for racial segregation. To assuage the conscience, the doctrine created "separate and equal" public facilities and services for African Americans and whites.
This segregation doctrine was officially approved in the Plessy v. Ferguson landmark case of 1896 by the U.S. Supreme Court.
Thus, the doctrine that supported racial segregation of blacks and whites by saying that "separate but equal" is known as the “segregation” doctrine.
