What court case was a major first win for the naacp?

In 1954, Thurgood Marshall and a team of NAACP attorneys won Brown v. Board of Education of Topeka, Kansas. In this landmark decision, the Supreme Court held that segregation in public education violated the Equal Protection Clause of the Fourteenth Amendment.

Explination:The NAACP or National Association for the Advancement of Colored People was established in 1909 and is America’s oldest and largest civil rights organization. It was formed in New York City by white and black activists, partially in response to the ongoing violence against African Americans around the country. In the NAACP’s early decades, its anti-lynching campaign was central to its agenda. During the civil rights era in the 1950s and 1960s, the group won major legal victories, and today the NAACP has more than 2,200 branches and some half a million members worldwide.
