Separate but Equal is a legal doctrine that originated from the Supreme Court decision in Plessy v. Ferguson (1896), which upheld racial segregation laws as long as the separate facilities for the races were considered equal. This principle allowed states to maintain racially segregated public facilities, including schools, as long as they provided equal services and quality. However, in practice, this often led to discrimination and unequal treatment, impacting the balance between minority and majority rights.
