The Brown vs Board of Education legal case was a very important part of history which essentially ended segregation among blacks and whites in schools and started to integrate them together.
Brown vs Board of Education started in the 1950's when a young African American girl had to walk over a mile to school everyday, but there was a school for whites very close by.
This was when the NAACP, which advocated for the rights and freedoms of colored people came in. They believed segregation among schools and "separate but equal" was in fact <em>not</em> equal.
Eventually, the Brown vs Board of Education case went to the Supreme Court, when finally in 1954 the case was won by the NAACP and integration between public schools began.
Many citizens and schools were against integration and many more rulings with the Supreme Court had to occur, but finally a few decades later all of the public schools in the United States were integrated among races and the "separate but equal" principle was no longer.
All of the above hope this helps
