 During the early 18th century in most states African-American students and Mexican American students were barred from attending schools with White Students.This was due to the post effects of the court case "Plessy v. Ferguson" (1896) where it was decided that educational facilities were allowed to segregate white students from students of color as long as the educational facilities were considered equal.Educational facilities did not follow the federal mandate, in a studies through taken from 1890 to 1950 of Southern States per pupil expenditures (1950s dollars) on instruction varied from Whites to Blacks.
