what principle was ocerturned in Brown v Board of education?

In the case of Brown v. Board of Education, the principle that was overturned was the "separate but equal" doctrine established in the Supreme Court's decision in Plessy v. Ferguson in 1896.

To understand how the "separate but equal" doctrine was overturned in Brown v. Board of Education, let's break it down:

1. Plessy v. Ferguson: In 1896, the Supreme Court ruled in Plessy v. Ferguson that racially segregated public facilities were constitutional as long as they were equal in quality. This decision established the "separate but equal" doctrine, which allowed for racial segregation to persist across various aspects of public life, including education.

2. The Board of Education: The case of Brown v. Board of Education involved a group of African American students who challenged the racially segregated public school system in Topeka, Kansas. They argued that segregation inherently created an unequal education system, thus violating the Fourteenth Amendment's Equal Protection Clause.

3. Overturning "separate but equal": In a unanimous decision in 1954, the Supreme Court ruled that the "separate but equal" doctrine was inherently unequal and violated the Fourteenth Amendment. The Court held that racial segregation in public schools had a detrimental effect on minority children, leading to feelings of inferiority and denying them equal educational opportunities. This landmark decision effectively overturned the principle established in Plessy v. Ferguson and laid the groundwork for further desegregation efforts.

So, to summarize, the principle that was overturned in Brown v. Board of Education was the "separate but equal" doctrine, which allowed for racial segregation based on the belief that separate facilities could be equal in quality. The Supreme Court's ruling in Brown v. Board of Education declared that this doctrine was inherently unequal and violated the Equal Protection Clause of the Fourteenth Amendment.
