Which called on states to desegregate "with all deliberate speed"?

Plessy v. Ferguson

the Southern Manifesto

Brown II

Brown v. Board of Education

The correct answer is Brown II.

Similar to Brown v. Board of Education, Brown II focused on ending segregation because B v BE made segregation illegal in schools.

The correct answer is: "Brown II".

Brown v. Board of Education was a case dicussed by the US Supreme Court, which led to the enactment of a landmark decision in 1954.

Brown v. Board of Education overturned the "separate but equal" principle, that had been accepted by a previous Supreme Court decision and declared segregation unconstitutional, claming that in practice, it actually deprived black students. The court published a deadline and all public schools nationwide had to abolish such practice and to adopt racial integration.

Brown v. Board of Education II was a decision issued in 1955 (one year later) by the US Supreme Court, that ordered schools which had not followed the provisions of the former Brown v. Board of Education decision, to do it "with all deliberate speed".
