What was the supreme court decision written by chief justice earl warren, in the brown v. board of education case?

The Supreme Court case Brown vs. Board of Education ruled that the doctrine (idea) of separate but equal in American society is unconstitutional. This case overturned the case of Plessy vs. Ferguson, which originally established the idea of "separate but equal."

This court case was monumental, as it declared segregated schools illegal. This ultimately leads to the integration of whites and African-Americans in public schools.

Chief Justice Warren gave the majority opinion of the court and discussed how segregated schools had a "detrimental effect" on African-American children. Even though schools were supposed to be separate but equal before this Supreme Court case, this was never really the case. White schools often had more resources and better buildings to learn in.
