Causes of brown v. Board of Education

The decision in Brown v. Board of Education was the Supreme Court of the United States of America's decision that brought an end to racial segregation in the US school in 1964. Before the judicial pronouncement in the Brown v Board of Education case, the Jim Crow Laws which held sway in the Southern States of the United States of America upheld racial segregation and discrimination against the Black Americans. The Jim Crow Laws were upheld by the decision in Plessy v. Ferguson.  The Jim Crow laws supported by the US Supreme Court decision in Plessy's case posited that the Black American was not to share public facilities like restaurants, restrooms, schools, public buses and trains with the White American. The decision which established the principle of "separate but equal", promoted segregation against the Black Americans, and the Black code was further enforced against the Black Americans.  Blacks were not allowed to attend schools attended by Whites. The plaintiff in the Brown v. Board of Education case instituted the action against the US Board of Education on the ground that the racial school segregation advanced by the decision in Plessy's case was a violation of the Fourteenth Amendment to the United States Constitution at that time. This is because the provision of separate facilities is inherently unequal. However, the decision brought liberation to the black race.
