Answer: The Supreme court ruled that segregation was unconstitutional in public schools
Explanation: Brown vs. Board of education was a Supreme Court ruling in 1954 that overturned the Plessy vs. Ferguson decision of 1896, led by Chief Justice Earl Warren. The Court ruled that "separate but equal" schools for blacks were inherently unequal and thus unconstitutional. This ruling fueled the Civil Rights Movement in the 1950s and 1960s as it also proved that segregation violated the 14th amendment to the constitution, which prohibits the states from denying equal rights to any person.
The goal of the parents was to stop segregation in public schools in order to move their children to closer schools in their neighborhoods. This led to the campaign that if segregation in public schools is unconstitutional, then segregation in all public places is unconstitutional.
