After Brown v. Board of Education (1954), the lawful segregation of African American children in schools became a violation of the 14th Amendment. In Swann v. Charlotte-Mecklenburg Board of Education (1971), the Supreme Court ruled unanimously that forced busing of students may be ordered to achieve racial desegregation. However, court-enforced school desegregation efforts have decreased over time.
