Institutionalized racial segregation was ended as an official practice by the efforts of such civil rights activists as Rosa Parks and Martin Luther King Jr., working during the period from the end of World War II through the passage of the Voting Rights Act and the Civil Rights Act of 1964 supported by President Lyndon Johnson. Many of their efforts were acts of civil disobedience aimed at violating the racial segregation rules and laws, such as refusing to give up a seat in the black part of the bus to a white person (Rosa Parks), or holding sit-ins at all-white diners.
Not all racial segregation laws have been repealed in the United States, although Supreme Court rulings have rendered them unenforceable. For instance, the Alabama Constitution still mandates that Separate schools shall be provided for white and colored children, and no child of either race shall be permitted to attend a school of the other race.

Although the high court remanded the case back to the lower courts, it is likely

that their decision will have the impact of forcing California to alter its practice of segregating by race in its reception centers.
According to the Civil Rights Project at Harvard University, the actual desegregation of U.S. public schools peaked in 1988; since that time, the schools have, in fact, become more segregated. As of 2005, the present proportion of black students at majority white schools 'a level lower than in any year since 1968.'
