At the same time other cases were going on in Delaware, Virginia, Kansas, and Washington DC challenging the legality of racially segregated schools. These cases were all put into one case called Brown v. Board of Education. .
Oliver Brown filed suit against the Topeka Kansas Board of Education on behalf of his daughter Linda Brown. Linda seven years old had to travel one hour and 20 minutes each morning to her school for black children. If the bus was on time in the morning it would drop her off a half hour early before the school opened. Her bus stop was six blocks from her home, where she had to cross a hazardous railroad yard. However, Linda's white peers attended a local school only seven blocks from her home. They did not have to walk 21 blocks nor cross a hazardous railroad yard. Oliver Brown argued the same conditions for his daughter. The NAACP got the Brown family to take Linda to Sumner Elementary, attended by white students, and asked to register her as a student. When Linda was turned away, she became the lead plaintiff in the case. Other black families joined in the litigation. And in 1951 the NAACP requested an injunction banning segregation in Topeka's schools. .
The Argument of 1952.
The NAACP, and Thurgood Marshall (later a Supreme Court Justice), acting as lead counsel, engaged in a careful legal war against Topeka's Board of Education. First the NAACP brought suit to secure segregation through the Plessy v Ferguson case "separate but equal." Now the NAACP was challenging the integrations of schools.
In 1952 The NAACP brought five cases before the Court. Such as Mclaurin v. Oklahoma state Reagents (1950). The Supreme Court in this case allowed a black man to attend classes in a all white school, but fenced him off from other students. And Sweatt v. Painter, a law school in Texas was solely created to avoid admitting black, and for the first time the court ordered to admit a black student into the previously all white school.
