How did the supreme court ruling in brown v. Board of education affect race relations in the United states during the 1950s?

The ruling of Brown v Board of Education changed race relations in the USA during the 50's by having children be able to be in the same school together, but it also made many people angry and had parents protesting outside schools. So it had negative and positive affects for people, but overall ended the belief of "separate but equal" in the United States.
