Final answer:
The Plessy v. Ferguson decision resulted in Jim Crow laws that enforced legal segregation in the South, creating separate and typically inferior facilities for black Americans.
Step-by-step explanation:
After the Plessy v. Ferguson decision, black Americans in the South were forced to endure legal segregation, which included systems of segregation known as Jim Crow laws. These laws mandated the separation of races in public and private life, enforcing separate facilities for black and white individuals in schools, public buildings, transportation, and more. The facilities provided for African Americans were generally inferior, a stark reality of the doctrine of "separate but equal" established by the Supreme Court in the 1896 Plessy ruling. This ruling was in place for more than half a century until it was overturned by the Supreme Court's decision in Brown v. Board of Education in 1954, which ruled that separate educational facilities are inherently unequal.
