Answer: The Supreme Court case Plessy v. Ferguson, not Choose, led to the doctrine of "separate but equal." In 1896, the Supreme Court ruled in Plessy v. Ferguson that segregation was constitutional as long as separate facilities for different races were "equal." This ruling established the legal doctrine of "separate but equal," which allowed for segregation in many aspects of American life, including education, transportation, and public accommodations.
It is important to note that Plessy v. Ferguson was later overturned by the Supreme Court in Brown v. Board of Education in 1954, which ruled that "separate but equal" was inherently unequal and violated the Equal Protection Clause of the 14th Amendment to the United States Constitution.
