Which best describes the circumstances that led to Brown v. Board of Education? A state university permitted an African American student to attend but not interact with white students. Orval Faubus sent the Arkansas National Guard to block African American students from attending white schools. An 8-year-old girl had to walk through a dangerous area to attend an African American school each day. Nineteen senators and seventy-seven representatives signed a document called the Southern Manifesto.

The case originated in 1951 when the public school district in Topeka, Kansas, refused to enroll the daughter of local black resident Oliver Brown at the school closest to their home, instead requiring her to ride a bus to a segregated black elementary school farther away.

A new case gave the NAACP another chance to challenge segregation. It was one of the most influential cases the Supreme Court has ever heard. The Brown case centered on 8-year-old Linda Brown. She had attended a school for African Americans which was a mile away from her home.

To get there, she had to walk through a dangerous railroad yard. Here's Linda and her little sister walking to school. Her father, Reverend Oliver Brown wanted her to attend a nearby all-white school, but she was denied the right to attend. So the NAACP took the case to court. Brown vs. The Board of Education was first tried in lower courts. Eventually, the case came before the US Supreme Court and was given the name Brown vs. Board of Education. Thurgood Marshall led the argument against segregation in this case. He argued that segregation violated the Fourteenth Amendment's guarantee of equal protection of the law
