Which historic court case banned racial segregation in California public schools?

The case that banned racial segregation in California public schools is Mendez v. Westminster. This landmark case, decided in 1947, was significant because it directly challenged the segregation of Mexican American children in public schools in Orange County, California. The court ruled that the segregation of students based on their ethnicity was unconstitutional, stating that it violated the Fourteenth Amendment's guarantee of equal protection under the law. This decision set a precedent and was a key legal step toward desegregation, influencing future cases including the more widely known Brown v. Board of Education, which addressed segregation nationwide. Mendez v. Westminster played a crucial role in civil rights advancements, making it clear that educational institutions should not racially discriminate.
