    Maryland shifted from local control of schools to a highly centralized system whereby the State Board with the State Superintendent selected textbooks, set the curriculum, certified teachers, approved school building designs, and distributed State funds.

Maryland began a formal system of segregated schooling that continued for ninety years.
