Racial segregation finished de jure in the United States in 1954, when a series of Supreme Court decisions were enforced in that sense. However, de facto segregation continued until the 1970s and persists in various degrees to present day.
The Brown v. Board of Education of Topeka was a Supreme Court Case that marked the end of racial segregation in the United States. The Court decided that state laws that governed segregation between black and white students in schools were unconstitutional. The ruling of the court was the first major victory of the anti-segregation and civil rights movement and contributed significantly to the abolition of segregation.
