Swann v. Charlotte-Mecklenburg Board of Education
Swann v. Charlotte-Mecklenburg Board of Education, 402 U.S. 1 (1971) was a landmark United States Supreme Court case dealing with the busing of students to promote integration in public schools.

 This was done to ensure the schools would be "properly" integrated and that all students would receive equal educational opportunities regardless of their race.
