Brown v. Board of Education II (often called Brown II) was a Supreme Court case decided in 1955. The year before, the Supreme Court had decided "Brown v. Board of Education", which made racial segregation in schools illegal. However, many all-white schools in the United States had not followed this ruling and still had not integrated (allowed black children into) their schools. In "Brown II", the Court ordered them to integrate their schools "with all deliberate speed."
