In 1967, Thurgood Marshall was confirmed as a Supreme Court Justice, making U.S. history as the first African-American to be confirmed for the position. He would remain in the U.S. Supreme Court for 24 years until he retired for health reasons. He left a legacy of upholding the rights of Americans as promised by the U.S. Constitution. Prior to making history as a Supreme Court Judge, Marshall made history as one of the lawyers appointed by the NAACP who argued in favor of Linda Brown in the landmark Brown v. Board of Education (1954) case that led to the desegregation of schools. This case automatically overturned provisions of the Plessy v. Ferguson case (1896).
