Final answer:
The Plessy v. Ferguson decision led to the enforcement of Jim Crow laws, legalizing racial segregation in public facilities in the South under the guise of 'separate but equal' until overturned by the Brown v. Board of Education case in 1954.
Step-by-step explanation:
The Plessy v. Ferguson 1896 decision allowed continued discrimination against African Americans, enforcing a legal system of segregation through what became known as Jim Crow laws. These laws mandated the separation of races in public spaces and facilities in the South, significantly impacting the daily lives of African Americans by instituting widespread racial segregation.
Enacted after the Civil War, Jim Crow laws enforced de jure segregation in all aspects of public life, including schools, transportation, restrooms, and restaurants. The Supreme Court's ruling in Plessy v. Ferguson supported the 'separate but equal' doctrine, allowing states to maintain unequal and segregated facilities so long as they were purportedly providing equal services to both Black and White individuals.
This interpretation of the law stood until the Brown v. Board of Education decision in 1954, which began the process of desegregation in public schools and signaled the end of de jure segregation.
