| As a litigator for the National Association for the Advancement of Colored People (NAACP) Legal Defense and Education Fund, Thurgood Marshall argued many important civil rights cases, including Brown v. Board of Education in 1954. His arguments greatly influenced the Supreme Court’s decision to outlaw racial segregation of schools in the United States. After President Lyndon Johnson appointed him to the Supreme Court in 1967, Marshall participated in many decisions that extended civil rights. |
