American students have attended school for nearly 70 years under the U.S. Supreme Court’s historic 1954 Brown v. Board of Education decision, which outlawed racial segregation in public schools.
But a new book uncovers a little-known by-product of the case: Educators and policymakers in at least 17 states that operated separate “dual systems” of schools defied the spirit of Brown by closing schools that served Black students and demoting or firing an estimated 100,000 highly credentialed Black principals and teachers.
