Answer:
Schools were segregated in the mid to late 1800s/early to mid 1900s becauase, well almost everything was segregated. laws were passed that whites had to be separated [segregated] from blacks. The supreme court cas in 1896, plessy v. fergusib was a significant case that upheld the constitutionality of racial segregation by ruling that separate facilties for different races were legal, as long as those facilties were equal to one another. this case prvided a legal justification for racial segregation for nearly 60 years until it was overturned by the case Brown v. Board of education in 1954. ~hope that helps.~ krista xx
